A month-by-month look at weather, wildlife, sea conditions and crowds — so you sail when it matters most to you.
The short answer: April–May and September–October give the best balance of great weather, reliable wildlife and sensible prices. June–September is peak season with flawless conditions but the highest cost and crowds. February is best avoided.
These shoulder months deliver the best overall experience: excellent conditions, reliable whale shark sightings, frequent manta encounters, moderate pricing and noticeably fewer crowds than peak season. Seas are among the calmest of the year — ideal if you are prone to seasickness.
Perfect dry-season weather: roughly 25–28°C, virtually no rain, calm seas and 25–35+ metre visibility. Whale sharks and mantas are at their most frequent, and June–August is the most likely window to see multiple whale sharks.
The trade-off: pricing runs 30–50% above off-season, boats fill to capacity, and advance booking of a month or more is essential.
Late season keeps great weather and reliable wildlife while prices ease well below peak. October is excellent for mantas at Manta Point but also marks the end of the manta season, so book early in the month for the best odds.
The wet season brings transitioning to rough monsoon conditions, swells of one to three metres and reduced visibility around 10–20 metres. January–February is the most challenging period, with February the toughest month and the lowest prices (30–40% cheaper). March is a transition month where wildlife begins returning and schedules increase.
Popular periods fill weeks in advance, and peak season often books out a month or more ahead. Shoulder seasons offer more flexibility but still reward early booking. If wildlife is your priority, target March–October and avoid February.
The right month depends on what you value most.
April–May or September–October — great weather, fair prices.
June–August — flawless seas, accept premium pricing.
February–March or November — lowest cost, weather trade-offs.
March–October for whale sharks and mantas; skip February.
