- Afternoon storms during wet season are typically brief (20–30 minutes to 2 hours), often followed by clear skies
- Despite off-season rainfall and hurricane-season designation, visitors often report abundant sunshine even in the traditionally 'worst' weather months
- High season (December–April) offers the most comfortable weather but also higher accommodation prices; low season (June–October) is budget-friendly with warm water and manageable weather despite rain risks
- The intense tropical sun is present year-round; sunscreen and UV protection are essential even during cooler months
