For Holy Monday forecast, partly cloudy to cloudy skies with isolated rainshowers or thunderstorms will prevail over Metro Manila, Luzon, Visayas and Mindanao.

Expect to experience warm and humid weather in the next three days in most parts of the country because of the ridge of high pressure area extending towards Northern Luzon, according to the Philippine Atmospheric, Geophysical and Astronomical Services Administration on Monday.

The high pressure area is associated with light winds, less rain clouds, and drier air.

Light to moderate winds blowing from the northeast to east will prevail over the country and the coastal waters throughout the archipelago will be slight to moderate.

Based on the PAGASA’s climatological record, the hottest temperature in Metro Manila was recorded on May 14, 1987 at 38.5 degrees Celsius.

Other parts of Luzon including Metro Manila may experience hotter days due to the ridge of high pressure area.

Temperature on Monday in Metro Manila will range between 22-35 degrees Celsius while the heat index will be 25.3-35.6 degrees Celsius.

The heat index is the human discomfort index that gives the “apparent” temperature or what human perceive or feel as the temperature affecting their body. High air temperatures and high relative humidity will give high apparent temperatures or indices. Full exposure to sunshine can increase the heat index by 9°C.
