Best Time to Dive
Optimal dive conditions and best visibility at Mpai Bay generally align with the dry season, from November through April. During these months, the regional climate provides calmer waters and less suspended particulate matter. Air temperatures during this period typically range from 27.2-29.1°C (81-84°F), contributing to comfortable surface intervals. Rainfall is minimal, often less than 5 mm (0.2 inches) per month from December to April, which significantly reduces runoff that could impact underwater clarity. The months of January, February, March, and December consistently receive an 'Excellent' dive score, reflecting prime conditions with lower wave heights and lighter winds. While May and October are rated 'Good', with slightly increased rain (up to 11.4 mm or 0.45 inches in October), they can still offer worthwhile diving. The period from June to September sees higher rainfall, reaching up to 20.1 mm (0.8 inches) in July, and increased wave activity, which may affect visibility and overall comfort. Planning dives within the drier window is recommended for the clearest views.
