Is October Right for You?
Advantages
- Perfect shoulder season pricing - accommodation costs drop 20-30% compared to peak dry season months, with luxury resorts offering their best packages
 - Outstanding snorkeling and diving conditions as water visibility reaches 25-30m (82-98 ft) with calmer seas after winter storm season
 - Fruit season peaks with mangoes, passionfruit, and local soursop at their sweetest - local markets overflow with produce at half tourist-season prices
 - Ideal temperature balance at 27°C (81°F) highs - warm enough for all water activities without the oppressive heat of summer months
 
Considerations
- Variable weather patterns mean 10 rainy days with afternoon showers lasting 30-45 minutes, requiring flexible scheduling
 - Some outer island day trips may be cancelled 2-3 days per month due to wind conditions, particularly to northern atolls
 - Higher humidity at 70% makes midday activities less comfortable - locals avoid outdoor exertion between 11am-2pm
