From Dec to May weather is perfect 98% of the time but now from June to Nov its rainy season with occasional typhoons but once a typhoon passes its nice for a while. Peak typhoon season is in October but Subic Bay hardly ever gets a direct hit, just the rain deluges. So I would guess June to Nov its 30% perfect and rainy the rest of the time.
Kermit I look forward to flying videos. Dont forget you flying property at Dunalley. Also Craigeborne Dam would be good for seaplane flying. And end of Opossum Bay is flyable. Also beaches at low tide make good runways and hills are good for chucking off gliders so no excuses for not flying.
