Abstract
Climate is one of the characteristics that distinguish one type of tourism from another. Climate data should be evaluated as an important
resource for the tourism industry, and because climate data is multifaceted, quantitative tools are required to identify climate suitability in
tourism. The current study looks into whether or not tourists base their decision to visit a destination, particularly a metropolitan city, on
the weather. Mieczkwski's (1985) Tourism Climate Index (TCI) and Tang's (2013) Holiday Climate Index (HCI) were used to
assess the effects of climate on tourism in Kolkata, a metropolitan city. With its rich cultural heritage, breathtaking leisure parks, and
enthralling architecture, Kolkata, the city of joy, attracts visitors from all over the world. The primary focus of this research is the
compatibility of the final tourist report (2014-2015) (latest report of West Bengal Tourism), which provides domestic and foreign
tourist data, and monthly TCI and HCI scores (April 2014-March 2015), which range from ideal to extremely unfavourable.
According to the findings of the current study, tourists who chose a metropolitan city as a tourist destination did so for reasons other than
climate suitability.

Introduction
Kolkata, the capital of West Bengal, is a metropolitan city known
for its intellect, culture, and magnificent performance in literature,
arts, science, social reforms, and socio-political movements
throughout history. The iconic landmark Howrah Bridge, lively
Princep Ghat, majestic Victoria Memorial, historic South Park
Street Cemetery, Shobhabajar Rajbari, St Paul's Cathedral, Indian
Museum, Marble Palace, Jorasako Thakurbari, Kalighat Temple,
Kumartuli, Birla Planetarium, Alipur Zoo, and other attractions
attract tourists from around the world (Annual Final Report of
Tourism Survey for the State of West Bengal (April 2014-March
2015))[1]. Kolkata is India's cultural capital, a city brimming with
talent and passion (Sofique, Ghosh, 2011) [2] has a tropical wet and
dry climate (Köppen climate classification: Aw) (Weatherbase
entry for Kolkata, 2006)[3], resulting in year-round warm to hot
weather with typical torrential monsoonal rain from June to
September (NOAA)[4]. Despite its enormous potential as a tourist
destination, Kolkata has seen a relatively low level of foreign
visitors (Chakraborty, Debnath, 2008)[5], althoughit has the
potential to become a heritage tourism hotspot (Clarke, 2014)[6].
Geographic locations, topography, landscape, flora and fauna, and
climate and weather variables all influence the attractiveness of a
tourist destination (Matzarakis, de Freitas, 2001)[7]. Because of the
multifaceted nature of climate variables, the relationship between
climate and tourism is complex (deFreitas, Scott, McBoyle,
2004)[8]. Depending on tourist preferences and sensitivities,
ASI-Score:3.00
climatic conditions may be perceived as a resource or a constraint
for tourism (Smith, 1993)[9]. Many tourist activities can be seen to
be related to specific weather conditions (Schrter de et al.,
2005)[10]. Tourists usually learn about the climate of their
preferred destination before choosing it or booking tickets; they
also like to check the weather before their trip (Hamilton, Lau,
2005)[11]. Though business, education, and cultural tourism are
less reliant on ideal climate, they can be reliant on seasonal optimal
climate (Amelung, Nicholls, Viner, 2007)[12].
There are several indices for quantifying a tourist destination's
climate suitability to tourists (Fichett, Hoogendoorn, Robinson,
2016)[13]. One of the suitable metrics for identifying climate
suitability for sightseeing is Mieczkowski's Tourism Climate Index
(TCI) (1985)[14], which combines seven climate variables. TCI
does not explain tourist activities; rather, it indicates how suitable a
location's climate is for sightseeing and shopping. It is one of the
most popular indices because it incorporates the thermal facet
(comfort), the physical facet (precipitation and wind), and the
aesthetic facet (sunshine) (Perch-Nielsen, Amelung, Knutti,
2010)[15].
Tang's (2013) Holiday Climate Index (HCI), which incorporates
the thermal facet (thermal comfort), physical facet (precipitation
and wind), and aesthetic facet (cloudiness rate), is a more accurate
tool for determining the climate suitability of urban tourism (Tang,
2013[16]; Scott, Rutty, Amelung, Tang, 2016[17]; Mahtabi, Taran;
2018[18]).

Research Objectives
The major objectives of this research:
1) To understand climate importance on tourism in Kolkata.
2) To analyse the compatibility of the Tourism Climate Index
(TCI) on Tourism in Kolkata.
3) To study the compatibility of the Holiday Climate Index
(HCI) on Tourism in Kolkata.
Material and Methods
1) Weather data was collected from World Weather Online[19]
which is a private source for weather data collection which
works on the latest holiday weather reports, ski conditions,
marine conditions and day to day forecasts for worldwide
towns and cities.
2) Annual Final Report of Tourism Survey for the State of West
Bengal (April 2014 - March2015) was used to calculate
domestic and foreign tourists in Kolkata as it is the latest
government document on tourism in West Bengal.
Two indices were used to validate climate suitability on tourists in
Kolkata. Tourism Climate Index and Urban Holiday Climate Index
(HCI) were used to calculate monthly TCI scores and HCI scores
respectively which ranged from April 2014 to March 2015 based on
the TCI rating categories (Mieczkowski 1985) and HCI rating
scheme.
Literature Review
Tourism, one of the most important sectors of the global
economy, is heavily influenced by climate (Scott, McBoyle,
Schwartzentruber 2004; Amiranashvili, Matzarakis, Kartvelishvili;
2008[25]). As climate plays an important role in tourism, there is a
large body of literature on tourism-related climate indices.
Mieczkowski developed one of these indices, the Tourism Climate
Index (TCI) in 1985 (Perch-Nielsen, Amelung, Knutti, 2010).
TCI, according to Mieczkowski (1985), is a "quantitative
evaluation" of the global climate for the benefits of global
tourism. He created a significant rating system to evaluate
meteorological variables that affect people's tourism experiences.
Mieczkowski computed TCI for 453 meteorological stations
around the world. Amelung, Nicholls, and Viner (2007) used TCI
to identify climatically and seasonally suitable tourist destinations
for their study, which is based on the likely impact of climate
change on the global tourism industry.
Amiranashvili, Matzarakis, and Kartvelishvili (2008) also
conducted a small study on Tbilisi, Georgia's capital, using TCI to
determine the climate potentiality on tourism. Furthermore,
Kubokawa, Inoue, and Satoh (2013)[26] used TCI to evaluate
climate factors over Japanese tourism, as well as estimated TCI
based on Japan's future climate data projections.
Cengiz, Akbulak, Alişkan, and Kelkit (2015) used TCI to assess
meteorological activity in relation to tourism activity in Anakkale,
Northwest Turkey. In another study, Roshan, Yousefi, and Fichett
(2015) computed TCI for 40 Iranian cities over a 50-year period
(1961-2010) to investigate the trend of climate variability in
tourism in Iran.
According to Fichett, Hoogendorn, and Robinson (2016), TCI is a
well-known and widely used quantitative tool for measuring
climate suitability for specific tourism destinations. However, they
found some limitations due to limited recording of sunshine data
in their study area of South Africa, so they used a mathematical
adaptation of TCI to facilitate more desired use of TCI.
Later, Mantao (2013) developed the Holiday Climate Index (HCI)
to fill a research gap by modifying the TCI as it has some
inadequacies in the rating system and component weightage. He
compared HCI ratings to TCI ratings in the past (1961-1990) as
well as future climate projections (2010-2039, 2040-2069, and
2070-2099) to investigate the climate suitability of tourism in
Europe's top 15 tourist destinations. Scott, Rutty, Amelung, and
Tang (2016) examined the climate suitability of European cities by
comparing TCI and HCI scores. They found HCI to be a more
precise quantitative tool than TCI.
Mahtabi and Taran (2018) used HCI to determine the best months
for tourism in two Iranian cities: Isfahan and Rasht. Climate is a
decision-making factor for tourism-related businesses, according
to another study ztürk, Göral (2018)[27]. They used HCI to analyse
climate potentiality on tourism destination marketing in Izmir
Provence, a Turkish port city.
ASI-Score:3.00
1. Tourism Climate Index(TCI):
TCI is a combination of seven parameters, among them three are
independent and two are in a bioclimatic combination (thermal
comfort components) (Table -2).
TCI= 8CLD+2CLA+4R+4S+2W — Eqn.1
Where,
CLD = the daytime comfort index (combination of mean
maximum temperature in C and the mean minimum relative
humidity (%),
CLA = the daily comfort index (combination of mean air
temperature in C and the mean relative humidity (%),
R = precipitation,
S = daily sunshine duration,
W = mean wind speed.
Here W, R and are rated on a scale from 0 (unfavourable) to 5
(optimal) while CLD and CLA are scaled from -3 to 5 (Table - 3)
(Mieczkowski, 1985; Perch-Nielsen et al.,2010; Kovacs & Unger,
2014[20]; Roshan, Yousefi, Fitchett, 2015[21]; Fichett,
Hoogendoorn, Robinson, 2016).
The thermal comfort components (CLD & CLA) were calculated
by Missenard (1933) equation (Eqn.-2). TCI provides the effective
temperature (ET) which determines the thermal exchange
between organism and environmental variables. Assuming normal
body temperature at 37°C and normal atmospheric pressure, the
equation of ET:
---Eqn. - 2
Where,
T = temperature (°C), Rh= relative humidity (%), and V = wind
speed ( m/s).
Eqn.-2 estimates the CLD (mean maximum temperature (C) &
mean minimum relative humidity (%) is needed) and CLA (mean
air temperature (C) & mean relative humidity (%) is needed). For
R, mean precipitation in mm, for S, mean monthly sunshine
duration and for W, mean monthly wind speed in m/s is needed.
For calculating CLD, mean maximum temperature (C) & mean
minimum relative humidity (%) and for CLA, mean air temperature
(C) & mean relative humidity (%) were provided in Eqn.-2

(Grillakis, Koutoulis, Tsanis, 2015)[22].
The total range of TCI value is rated -30(impossible) to 100(ideal)
(Table 4) (Scott, McBoyle, Schwartzentruber, 2004[23]; Amelung,
Nicholls, 2007; Cengiz, Akbulak, Çalişkan, Kelkit, 2015[24]).
correlation coefficient (0.70) shows some extent of climatedependent tourism in the case of foreign tourists.
2. Urban Holiday Climate Index (HCI)
HCI is a combination of five parameters among them two are in a
bioclimatic combination three are independent parameter (Table 6)
HCI= 4T + 2A+(3R+W)
---- Eqn.- 3
Where,
T = Thermal Comfort, A = Cloud cover, R = Precipitation, and
W = Wind. (Tang, 2013).
The effective temperature was used to measure 'Thermal Comfort
(T)', which means the same Missenard (1933) equation (Equation
2)calculates Thermal Comfort(T) which is previously used to
calculate CLD & CLA in TCI. The rating scheme of HCI ranges
from 10 to -10 (Table - 7).
Finally, the Pearson’s Product Moment correlation coefficient was
computed to find out the compatibility of tourist data and TCI
scores and HCI scores.

Tourism in Kolkata (Source:www.worldweatheronline.com/kolkata-weatherhistory/west-bengal/in.aspx)
Results & Discussions:
TCI and Tourism in Kolkata:
a) TCI was calculated using climatic variables which were rated
based on the rating scheme of Mieczkowski (Table - 3). Table
- 9, 10 &11 show month-wise climate variables and their rating
scheme for the year 2014 and 2015 in Kolkata.
b) Scott &McBoyle (2001)[28] model explained there are six
annual distributions (poor, optimal, winter peak, summer
peak, dry season peak and bimodal-shoulder peak) based on
natural resources of climate. Kolkata has a winter peak
distribution (Fig.1) which represents that winter seasons are
preferably suitable to visit Kolkata, is explained by monthly
TCI scores of 2014 and 2015 (Table - 12).
c) Where the monthwise TCI scores (2014 and 2015) show
November to January is 'excellent' to 'ideal' for tourism as
excessive heat and rainfall caused the monsoon season June to
September unfavourable for tourism activities in Kolkata.
d) The present study evaluates the compatibility of TCI scores
and tourist data, as there was only the last “Final Report of
Tourism Survey for the State of West Bengal (April 2014March 2015)”, Ministry of Tourism, Government of India,
TCI was implemented to find out the climate suitability of the
months April 2014 to March 2015.
e) TCI scores of April 2014 - March 2015 shows November to
February (TCI scores (82 to 94) was the most suitable time to
visit and July (TCI scores 26) was very uncomfortable for
tourism in Kolkata (Fig.2). The tourist data represents the
scenario that there is a huge difference in the number of
leisure domestic tourists and the number of leisure foreign
tourists (Table - 13).
f) Domestic Tourists in Kolkata, 2014-2015 (Table -10, Fig. 3)
differ from the TCI scenario as tourists visit Kolkata in July
(TCI category = very unfavourable) were more than in
November (TCI categ ory = excellent).
g) The correlation coefficient was +0.49 between TCI scores
and leisure domestic tourists in 2014-2015. Though the

HCI and Tourism in Kolkata
a) Holiday Climate Index (HCI) shows the month-wise
distribution of HCI scores for the year 2014-2015 (Fig.4).
HCI have been calculated using the rating on climate variables
of Kolkata (Table - 14). The rating scheme is based on Tang's
rating scheme (Table - 7).
b) The HCI shows July is extremely unfavourable and December
is ideal for tourism in Kolkata. Monsoon season (June-
65

September) is not a climate suitable season where the winter
season (November- February) is the most favourable season
for tourism in Kolkata (Table -15, Fig. 5).
c) The correlation coefficient of HCI scores and leisure
domestic tourist data is low (0.34) which denotes domestic
tourist are not at all bothered by the climate though the
correlation coefficient is high (0.82) in the case of leisure
foreign tourists and HCI scores.

Findings:
1) The present study shows the winter season is the most
preferable season to visit Kolkata.
2) Monsoon season is unfavourable for sightseeing in Kolkata.
3) TCI and HCI scores are more compatible with foreign tourist
flow than domestic tourist flow.
4) There was relatively less foreign tourist flow than domestic
tourist flow in case of numbers in the latest government
tourist data.
5) The highest foreign tourist flow was seen in 2014-2015 in
December.
Conclusion
With its rich cultural heritage, breathtaking leisure parks, and
enthralling architecture, Kolkata, the city of joy, attracts visitors
from all over the world. The main focus of this research is the
compatibility of the final tourist report (2014-2015) (latest West
Bengal Tourism report), which provides domestic and foreign
tourist data, and monthly TCI and HCI scores (April 2014-March
2015), which range from ideal to extremely unfavourable.
According to the findings of the current study, tourists who chose
a metropolitan city as a tourist destination did so for reasons other
than climate suitability.
