Pohnpei weather in March

Forum posters describing diving conditions across Micronesia note the final months of the year bring the rainier stretch with murkier underwater visibility, implying the mid-year months including August offer comparatively better diving conditions. Posters are direct more broadly that Pohnpei is a place where it rains essentially every day regardless of season, a defining feature of its consistently wet, tropical climate rather than something unique to any one month. Given the limited destination-specific detail for August exactly, this note leans on that broader pattern: expect warm, humid conditions with regular daily rain, but with underwater visibility and overall conditions trending better than the wetter final quarter of the year. Posters generally rate August as reliably rainy but among the better months for diving-focused visits to Pohnpei.

Forum posters describe Pohnpei bluntly as a place where it rains almost every single day, a direct consequence of the roughly 80% of the island covered in mountainous rainforest - genuinely one of the wettest inhabited places on Earth regardless of month. Posters consistently note that diving and boat tours can get rearranged around passing squalls, but that showers here tend to be heavy and brief rather than settling in for the whole day. Given how thin destination-specific monthly detail is on the forum, this note leans on that well-established year-round wet-tropical pattern: February sits within Pohnpei's relatively drier first-quarter stretch, but 'drier' here still means frequent rain is the norm, not the exception.
