The hot weather season in India lasts from March to May. Temperatures are highest during this time, reaching 38°C in March in the Deccan plateau, around 42°C in parts of Gujarat and Madhya Pradesh in April, and commonly reaching 45°C in northwestern India in May. Coastal areas experience lower temperatures due to ocean influences. Towards the end of May, a low pressure area develops over northern India, bringing strong hot winds called "loo" and dust storms. Precipitation is low except for some thunderstorms and nor'westers that provide temporary relief and small amounts of rainfall. Local winds include "mango showers" and "kaal baishak

3. Duration
 India experiences the hot weather
season from the month of March to
May.
 This is the season of extreme heat
which comes from the sun.
 This is also known as the summer
season.
 This is the hottest of the four seasons
falling after spring and before autumn
season.
 This is the season of the king of fruits,
Mango.

4. • The apparent northward movement of the sun
leads to the global heat belt to shift northward.
• This influence of shifting of heat belt leads to
the rise in temperature (high temperature).
• Thus, India experiences summer season from
March - May.

5. In March, the highest temperature
is about 38° C recorded in the
Deccan plateau.
 In April, Gujarat and Madhya Pradesh
have temperatures around 42° C.

6.  In May, 45° C temperature is
common in the north-western
parts of India.
 In peninsular India, temperatures
remain lower due to the moderating
influence of the oceans

7. Pressure And Wind Conditions
• The summer months experience rising temperature
and falling air pressure in the northern part of the
country .
• Towards the end of May , an elongated low-pressure
area develops in the region extending from the Thar
Desert in the Northwest to Patna and Chotanagpur
plateau in the East and Southeast .
• A striking feature of the Hot Weather season is 'loo' .
These are strong , gusty , hot dry winds blowing
during the day over the North and Northwestern
India .
• Dust storms are very common during the Month of
May in Northern India .

8. Precipitation
 This season receives only one per cent of the annual
rainfall.
 In the northeastern parts of the country, dust storms
bring little rainfall.
 These storms bring temporary relief as they lower the
temperature and may bring light rain and cool breeze.
 This is also the season for localised thunderstorms,
associated with violent winds, torrential downpours,
often accompanied by hail.
 The norwesters bring some rainfall in Assam, West
Bengal and Odisha. The intensity of rainfall is high.
This rainfall brought by the norwesters is known as
the spring storm showers.
 This small amount of rainfall is very useful for the
cultivation of tea, jute and rice and is known as tea
showers in Assam.
 Coastal areas of Kerala and Karnataka receive rainfall
from thunderstorms.
 Such showers are called mango showers in Tamil Nadu
and Andhra Pradesh because they are very beneficial
to mango crop.

9. CHARACTERISTIC
FEATURES
Characteristic features of hot weather season are :
The season is marked by dry weather and excessive heat.
The sun shines directly over Tropic of Cancer.
Thunderstorms accompanied by dusty winds are
common.
Range of temperature is very low in coastal region.
The whole of tropical India, experiences very high
temperature.
The range of temperature is quite high in the interior
parts of the country.

10. CHARACTERISTICS
FEATURES
• The following are the local winds of the
Hot/Summer season:
• KAAL BAISAKHI: These are the localised
downpours, followed by violent winds,
torrential precipitation brought by the
hailstorm. Such winds transpire in West
Bengal.
• LOO: These are powerful, robust, hot dusty
winds blowing throughout the day over
north and north-west India. Such winds
occur during the summer season and dust
storms are frequent.
• MANGO SHOWERS: mango showers are
the showers that occur in the period before
the monsoon. Such showers take place in
Karnataka and Kerala at the conclusion of
the summer season.

11. Temperature Conditions 1) March- maximum temperature is 38 degree C (Deccan Plateau).
2) April- around 42˚C in Gujarat and Madhya Pradesh.
3)May- common temperature is 45˚C in the northwestern parts of the country.
4)Due to moderating influence of the oceans, temperature remain low in peninsular India.
Pressure Conditions 1) Low pressure conditions develops in the region from the Thar Desert in the northwest to Patna
and Chotanagpur plateau in the east and the southeast (towards the end of may).
2)circulation of air begins to set around this trough.
Direction of Wind 1) Since a low pressure area develops in India , a complete reversal of the direction of winds can
be seen.
2)The direction of summer monsoon is South West because winds deflect towards their right in
the northern hemisphere.
Distribution & amount of
rainfall
1)This season is not totally rainless (only one per cent of the annual rainfall).
2)In the northeastern parts of the country, dust storms bring little rainfall.
3)The precipitation in Kashmir is mainly in the form of snow caused by western disturbances.
4) Coastal areas of Kerala and Karnataka receive rainfall from thunderstorms.
Important Features 1)Loo- Hot , dry, dusty winds blowing during day over north and northwest India.
2) Kaal Baisakhi- local thunderstorms in West Bengal which is associated with violent wind,
downpours and hail.
3)Mango Showers- (I) pre monsoon showers (ii) common in Karnataka and Kerala (iii) helps in
early ripening of mangoes.
