When to go

Best time to visit Subic Bay

Subic Bay is diveable yearround, but conditions shift with the Philippines' two main seasons.

Best overall window

Nov-Apr

Drier season conditions and more predictable mornings; easier planning for boats and road trips.

Outside that window

Rainier season and southwest monsoon influence on western Luzon; more wind (often 15 km/h to 25 km/h) and higher cancellation risk.

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.

Month-by-month planner

The overall row stays visible so you can compare it against the currently selected scope.

Always true for this destination
  • Subic's protected bay can still deliver dive days in the rainy season, but keep your itinerary flexible for typhoons and plan Grande Island trips only when the forecast is calm.
Seasonal cautions
  • May, Oct: Transition months. May can be hot, and October can still be humid with improving seas.
  • Jun to Sep: Rainier season and southwest monsoon influence on western Luzon; more wind (often 15 km/h to 25 km/h) and higher cancellation risk.
