The Philippines is located near the equator which explains its tropical climate. It is hot and humid though some rainfall can be expected throughout the year. Compared to the western countries, there are only two seasons considered here namely the dry and the wet season.
Between November and May is the dry season considering March until May as summer. Towards the end of May, rainfall could already be expected. Though officially, June is the start of the wet or the rainy season. Typhoon or “bagyo” as called locally is common in the Philippines which usually strikes between July to September peaking in August on average. Yearly, there’s an average of 19 typhoons that pass the country but only nine reach the land area. PAGASA is the government agency responsible for typhoon warnings.
Ideally, it is best to visit the country between November to February when it is dry and cool. Typhoons are less likely to form during these months as well. In the summer period between March and May, the temperature could reach as hot as 38 degree Celsius. During this time, resort parks, and rivers are the popular destination of the city dwellers since there’s no nearby beach from Santiago City Isabela.
In general, it is much cooler in Santiago City compared to Manila especially in the evening and early morning. This could be explained by the mountain ranges around it. The cold air from the surrounding mountain ranges slide down to the plain of the valley. That said, the temperature could also cools down to 10 degrees Celsius between November and February. Thus, remember your sweater when you go to here in the north.
