General Weather Patterns

• Temperature: Temperatures are consistently warm. Expect average highs in the 80s Fahrenheit (27-32 Celsius) and lows in the 70s Fahrenheit (21-27 Celsius).
• Trade Winds: These prevailing winds, blowing from the northeast, create a cooling effect and influence rainfall patterns.
