Climate Zone Map of India

Climate Zones

The first step in following the ECBC is determining the appropriate climate zone of the building site which will
dictate the specific requirements for design and construction of the building
systems and components. India possesses a large variety of climates, which can
be broadly categorized into five regions with distinct climates. The five
climate zones, illustrated in the following map are normally designated as hot
and dry, warm and humid, composite, temperate, and cold. The classification of
climate for different types of buildings is an aid to the functional design of
buildings. Our country is zoned into several regions such that the differences
of climate from region to region are capable of being reflected in building
design, warranting some special provision for each region.

The significant difference in the climatic data across these zones defines unique thermal comfort requirements
for buildings located in different zones. Following broadly highlights the
differences in weather data in the five climate zones and Table 1 provides a
list of major cities in India with respect to their climate zones. These
differences in the weather profile translate into unique requirements for building thermal comfort and architectural responses for the different climate zones. (See in Map below).

Climate Zone	Description	Mean Temperature (°C)					Mean Relative humidity	Annual Precipitation	Sky Conditions	Places
		Summer midday (High)	Summer night (Low)	Winter midday (High)	Winter night (Low)	Diurnal Variation
Hot and Dry	High temperature \| Low humidity and rainfall \| Intense solar radiation and a generally clear sky \| Hot winds during the day and cool winds at night \| Sandy or rocky ground with little vegetation \|Low underground water table and few sources of surface water.	40 to 45	20 to 30	5 to 25	0 to 10	15 to 20	Very Low 25-40%	Low <500 mm/ yr.	Cloudless skies with high solar radiation, causing glare	Rajasthan, Gujarat, West- ern Madhya Pradesh,Central Maharashtra etc.
Warm and Humid	Temperature is moderately high during day and night	30 to 35	25 to 30	25 to 30	20 to 25	5 to 8	High 70 to	High > 1200 mm/yr.	Overcast (cloud cover ranging between 40 and	Kerela, Tamil- nadu, Costal parts of Orissa and Andhra Pradesh etc.
	\| Very high humidity and rainfall \| Diffused solar ra- diation if cloud cover is high and intense if sky is clear						90%		80%), causing unpleasant glare
	\| Calm to very high winds from prevailing wind direc- tions \| Abundant vegetation \| Provision for drainage of water is required
Temperate	Moderate temperature \| Moderate humidity and rainfall \| Solar radiation same throughout the year and sky is generally clear \| High winds during summer depending on topography \| Hilly or high plateau region with abundant vegetation	30 to 34	17 to 24	27 to 33	16 to 18	8 to 13	High 60 to	High > 1000 mm/yr	Mainly clear, occasionally overcast with dense low clouds in summer	Bangalore, Goa and parts of the Deccan
							85%
Cold (Sunny/ Cloudy)	Moderate summer temperatures and very low in winter \| Low humidity in cold/sunny and high humidity in cold/cloudy \| Low precipitation in cold/ sunny and high in cold/cloudy \| High solar radiation in cold/sunny and low in cold/cloudy \| Cold winds in winter \| Very little vegetation in cold/sunny and abundant vegetation in cold/cloudy	17 to 24/20 to	4 to 11/17 to	(-7) to 8	(-14) to	25 to 25 /5	Low: 10-	Low: < 200 mm/	Clear with cloud cover < 50% / Overcast for most of the year	Jammu &Kash- mir, Ladakh, Hi- machal Pradesh, Uttaranchal, Sik- kim, Arunachal Pradesh
		30	21	/4 to 8	0 /(-3)	to 15	50% /High:	yr /Moderate 1000mm/yr
					to 4		70-80%
Composite	This applies when 6 months or more do not fall within any of the above categories \| High temperature in summer and cold in winter \| Low humidity in summer and high in monsoons \| High direct solar radiation in all seasons except monsoons high diffused radiation \| Occasional hazy sky Hot winds in summer, cold winds in winter and strong wind in monsoons \| Variable landscape and seasonal vegetation	32 to 43	27 to 32	10 to 25	4 to 10	35 to 22	Variable Dry Periods=	Variable 500-	Variable Overcast and dull in the monsoon	Uttar Pradesh, Haryana, Punjab, Bihar, Jharkhand, Chattisgarh, Madhya Pradesh etc.
							20-50% Wet	1300 mm/yr, during monsoon reaching 250 mm in the wettest month
							Periods= 50-95%
