San Mateo

San Mateo stands out as one of Calabarzon's larger cities and a weather reference point for the wider Philippines region.

Like much of Philippines, San Mateo has a tropical monsoon climate — hot temperatures throughout the year with a clear contrast between the rainy season (roughly May to October) and the drier, sunnier months from November onward. Humidity is consistently high, with daytime highs between 30°C and 35°C.

During the rainy season, San Mateo can see several centimetres of rain in a single afternoon. Storms often arrive late in the day and clear by evening, leaving humid but cooler conditions overnight.

Visitors looking for the best weather in San Mateo should aim for the November–February window, when the monsoon has passed and humidity drops noticeably.
