Hot & Dry Season: March to May
Climbing gets really challenging due to the heat and humidity. Tolerable if you’re used to the tropical climate, otherwise, be ready for a heatstroke. Climbing is recommended to be limited to early mornings and late afternoons. Constant hydration is a must.
Rainy Season: June to October
As the Philippines is sitting on the typhoon belt, when it rains, it pours. Often. Only way to avoid frustration is by tuning into weather reports. Apart from knowing if water flows onto certain walls when raining, also important to be familiar with access to the crag as dirt roads and trails can get really muddy/slippery.
Cool & Dry Season: November to February
The best time to climb in the Philippines—after the rainy season and before the hot summer begins. Trails are dry so access is safe and easy. Walls stay dry so there will be plenty of routes to choose from. Climbing under the noontime sun is becomes bearable.
Sad to say, global warming has taken its toll on Philippine weather. Nowadays we have long periods of dryness during the supposed-rainy season and typhoons dropping by in the supposed-dry seasons. Therefore, we advise to check the weather report before hitting the road to the crag.
