We have tried to develop index for climate change vulnerability   and Ecosystem Goods and services.

You may see this. May be of some help, pl. If need be we may discuss.

Check the following links, possibly to be useful for you:

• The main link to UTCI (Universal Thermal Climate Index): http://www.utci.org/index.php
• On how to calculate UTCI: http://www.utci.org/utcineu/utcineu.php

I also found an article that could be of interest for you (see the attachment)

thanks a lot i will go through attachment

The fundamental premise of the CEI is that humans require a reasonably  consistent degree of comfort and the energy required to achieve the comfort can be used to quantify the climatic impact on a building by outside air. The CEI is  calculated based on psychrometric chart. It calculates the energy required to  condition any weather hourly ordinate to the nearest boundary of a human comfort zone and operates on a unitary air flow. The human comfort zone was derived from  existing comfort ranges including ASHRAE Standard 55 and previous research  outcomes.

The subsequent, the human comfort zone of the CEI is defined based on the following assumptions:

PMV: -0.5 to +1.0

Moisture content: 0.004 kg/kg

Relative humidity: 70 %

Ta (air temperature) = Tr (mean radiant temperature)

Clothing insulation: 1.0

Metabolic rate: 1.1

Air velocity: 0.1 m/s

It is noted that the upper limit of PMV is set as +1.0, which is higher than that in ASHRAE Standard 55. This takes into account the actual acclimatization and

comfort expectations of the inhabitants and also reflects slightly relaxed summer conditions which are generally accepted in sustainable building designs.

In addition, in contrast to ASHRAE standard, there is a lower limit of moisture content (0.004 kg/kg) introduced to the comfort zone to address some potentially discomfort factors, such as skin drying, irritation of mucus membranes, dryness of the eyes and static electricity generation.

Human comfort zone used in the CEI provides a reasonable representation of good human comfort on a global scale, determined using the PMV formula which is set out in  ISO 7730 along with the above assumptions

thank u sir 

Just do not forget that Eskimos may not find 'comfort' zone of climate in central Africa  really comfortable like for Africans and vice versa.  Humans, like bear species or any other animal species,  are adapted to climate by many generations.

yes but for that first they must be originate or born in that area or they most live in that particular area for long time but tourist are moving for short period they will not able to adjust even their aims are also different which will not fulfill if they will not adjust or adopt therefore it is important to calculate climate comfort index

You won't be able to calculate it, because climate changes much faster than humans can anticipate or predict. You can say the climate is pleasant with average temp / humidity. if there are extreme weather conditions tourist will hear it in the news.
