When to go

Best time to visit Apo Reef Natural Park

Apo Reef sits off the west side of Mindoro, so sea state is strongly influenced by Philippine monsoon patterns.

Best overall window

December to May

More reliable crossings and calmer seas for an offshore reef.

Outside that window

Habagat rain and wind can increase surface chop. July to October is also the peak tropical cyclone window in the Philippines.

Choose your trip style

Start with the overall answer, then switch only when scuba, freedive, snorkel, or topside timing changes the trip in a meaningful way.
