PAGASA classifies heat index readings from 33°C to 41°C as extreme caution, during which heat cramps and heat exhaustion are possible. Continued exposure and physical activity could lead to heat stroke.

The heat index measures how hot conditions feel to the human body by combining air temperature and relative humidity.
