2.2. Project Site Location

Greater Noida has a hot and humid climate for most of the season. The city climate becomes

very hot during the month of June which is followed by monsoon and it continues till

September. Monsoon is quite unpredictable where you can’t predict which way they will turn.

Winter in Noida is very chilly which peaks in at the start of November. Winter season continues

till the month of February. The foggy and chilly weather during winters makes Greater Noida’s

climate a tough one to confront with.

According to the Bureau of Indian Standards, the town falls under seismic zone-III, in a scale

of I to V (in order of increasing proneness to earthquakes) while the wind and cyclone zoning

is “very high damage risk”, according to UNDP report.

Address : NETRA NTPC Limited

E-3, Ecotech II, Udyog Vihar, Greater Noida, Uttar Pradesh 201306

Location : 28°30’10”N 77°27’57”E

Summer : In summer i.e. from March to June the weather remains hot and

temperature ranges from maximum of 45°C (i.e. 113°F) to minimum of

23°C (73°F).

Monsoon : Monsoon season prevails during mid-June to mid-September with an

average rainfall of 93.2 cm (36.7 inches), but sometimes frequent heavy

rain causes flood.

Winter : The cold waves from the Himalayan region makes the winters in Greater

Noida very chilly. Temperatures fall substantially down to as low as 3 to

4º C at the peak of winter. Greater Noida is not aloof to the problems of

fog and smog. In January, dense fog envelopes the city, reducing visibility
