In contrast, summer months, from June to September, bring warmer air temperatures, typically ranging from 24-27°C (75-81°F), alongside very low rainfall, usually less than 1 mm monthly. Such seasonal patterns highlight summer's appeal for warmer surface intervals, while spring and autumn provide a comfortable balance. Wave heights are generally manageable year-round, typically below 1 meter, with slightly higher averages in winter. Despite these seasonal shifts, dive scores consistently rate as "Good" or "Excellent" across all months, indicating reliable diving conditions regardless of the time of year.
