Banda Islands in April

April through October brings the driest weather and calmest seas. May and June offer the best conditions — minimal rain, light winds, and excellent underwater visibility. July and August see more visitors, though 'crowded' here means maybe 50 tourists total. September and October can be perfect, with warm water and clear skies. But weather patterns have become less predictable in recent years. November through March brings monsoon rains and rough seas. Ferry services get canceled regularly, and diving conditions deteriorate. Many guesthouses close during this period. If you're stuck due to weather, embrace it — there are worse places to be stranded than a tropical island with 400-year-old nutmeg trees.
