The first time I visited the Philippines I almost completely messed up my vacation because it was in the month of June.
I spent almost 10 days at home unable to do anything or go anywhere because it was during the rainy season.
In June the weather is extremely humid in the Philippines and you will almost certainly experience a typhoon.
I experienced Bagyo Frank that killed a lot of people in Iloilo but it didn’t cause too much damage in San Ildefonso Bulacan, the former Hacienda Buenavista, a rather elevated place that, contrary to the neighboring province of Pampanga, is not too affected by baha.
However I spent several days at home some of which without electricity or internet.
I was able to go on a few trips to the Hundred Islands, Tagaytay, Manila and other places but most of the time it rained cats and dogs and I couldn’t do anything.
My second trip was ideal because it took place in December and in December the weather in the Philippines is just perfect: no bagyo, there is sunshine and it is not too hot, on the contrary early in the morning and in the evening it is medyo presko.
In Baguio City it was actually very cold and I was wearing short trousers and a T-shirt!
So if you choose to visit the Philippines avoid the rainy season and, if possible, do it in December or January when the sun shines and it is not too hot and humid.
