Best Time to Dive
Planning a dive at Karon Rock is best done from late October through June, a period offering most favorable conditions. Monsoon season, from July to September, typically brings higher rainfall and increased wave action, affecting dive suitability. Peak diving months, specifically November through April, consistently see air temperatures around 27-29°C / 81-84°F. Rainfall remains notably low during this period, often under 5 mm, which improves underwater visibility and promotes calmer seas. January, for example, often records minimal rain at just 0.85 mm, alongside air temperatures nearing 28°C / 82°F. Wave heights are also considerably reduced, averaging 0.5-0.6 meters / 1.6-2.0 feet, in contrast to 1.2-1.3 meter / 3.9-4.3 foot conditions common in September. Diving remains possible outside this prime window, though it depends on beach conditions and local weather evaluations.
