Heat Wave
Heat wave is considered if maximum temperature of a station reaches at least 40°C or more for Plains, 37°C or more for coastal stations and at least 30°C or more for Hilly regions. Following criteria are used to declare heat wave:
- a) Based on Departure from Normal
o Heat Wave: Departure from normal is 4.5°C to 6.4°C
o Severe Heat Wave: Departure from normal is >6.4°C
- b) Based on Actual Maximum Temperature (for plains only)
o Heat Wave: When the actual maximum temperature ≥ 45°C
o Severe Heat Wave: When actual maximum temperature ≥47°C
To declare heatwave, the above criteria should be met at least in 2 stations in a Meteorological sub-division for at least two consecutive days and it will be declared on the second day.
