Indonesia
Best Time to Visit Tomari
Tomari, a small coastal settlement in West Papua, has a tropical rainforest climate with no true dry season. The best time to visit balances the least rainfall with manageable humidity and reasonable flight availability.
✦ Go in October or November for the best weather, fewer crowds, and lower prices.
✅ Best months
October to December: these months have the lowest average rainfall (around 150-200mm/month) and the most consistent sea conditions for diving and island trips. Crowds are modest outside school holidays.
🔥 Peak season
July and August: the main dry-season window for Indonesia. Hotels in Manokwari and nearby homestays often sell out, and prices rise 30-50%. The Tomari Festival (late July) draws local visitors.
💷 Shoulder (best value)
May and June: rainfall is still moderate (200-250mm/month), flights are cheaper, and you avoid the July-August peak. Good visibility for snorkelling without the premium pricing.
🌙 Quietest & cheapest
January to March: the wettest months with 300-400mm of rain. Many guesthouses drop rates by 40%, but flights can be cancelled or delayed. The sea is rougher; dive trips are less reliable.

🧳 What to pack
Pack a lightweight, waterproof jacket or poncho even in the 'dry' months; rain can appear without warning for 20-minute downpours.
