Water Temperature: Daily Trends, Historical Records, and Forecast

✅ As of today, the minimum water temperature is above 82°F (28°C). This is very warm water, which may feel almost hot to most people. Swimming in such conditions is perfect for those seeking relaxation and comfort in the water. These waters are often preferred for relaxation in hot weather, as the water temperature does not cool the body significantly. However, it is important to remember that in such warm waters, caution is necessary, as prolonged exposure without rest can lead to overheating.

It is important to note that these swimming tips and recommendations apply only in good weather. When the air temperature is below 68°F (20°C), and sometimes even below 77°F (25°C), swimming can be unpleasant even with relatively high water temperatures.

Annual Water Temperature Trend

Roatán, a Honduran island in the western Caribbean, offers warm tropical seas throughout the year thanks to its position on the Mesoamerican Barrier Reef. Water temperatures typically range from about 26 °C in the coolest months of December through February, rising to roughly 28–30 °C during the warmest period from June to September. Transitional months such as March to May and October to November generally see temperatures around 27–29 °C. These moderate fluctuations mean that seawater remains comfortable for swimming year-round without the need for heavy thermal protection; on rare cooler days some visitors might prefer a thin shorty wetsuit, but most swimwear is sufficient even in winter. Water clarity is usually good, especially outside of rains, supporting pleasant surface conditions and attractive underwater visibility.
