Actual nearshore water temperatures may fluctuate by several degrees from the reported values, especially following heavy rainfall or extended periods of strong winds. Certain wind patterns can cause colder, deeper waters to rise and replace the sun-warmed surface water, leading to noticeable variations.
Our forecast is based on a proprietary mathematical model that considers real-time water temperature changes, historical trends, key weather patterns, wind strength and direction, and air temperature specific to each region. Additionally, we incorporate data from other resorts to enhance accuracy.
Water temperature data for this location is gathered from various sources, including buoys and satellite sea and ocean surface maps provided by the NOAA agency. We also incorporate data from local authorities in each specific location worldwide to ensure more accurate temperature readings.
Annual Water Temperature Overview by Month
Monthly Water Temp Ranges
Annual Water Temperature Trend
Salt Marsh in Jamaica is a coastal wetland area characterized by shallow tidal channels, mangrove fringes and brackish pools rather than extensive sandy shores. Water temperatures in and around the marsh follow the warm tropical pattern typical of the region, with winter months (December–February) usually around 26–27°C, spring (March–May) warming to approximately 27–28°C, summer (June–August) peaking near 28–30°C, and autumn (September–November) generally between 27–29°C. Because the marsh is shallow and influenced by freshwater inflows and tides, surface temperatures can vary more from hour to hour than in open sea, and sun-warmed pools may feel several degrees higher on calm days.

Swimming Conditions
Swimming directly in the marsh is often limited by the habitat: soft mud, submerged vegetation and narrow channels make it less suitable for typical beach bathing, though wading and sheltered paddling can be pleasant when water is near the higher end of the seasonal range. Visitors seeking conventional beach holidays and clear-water swimming commonly use nearby coastal beaches and reefs where conditions are safer and visibility better, with sea temperatures matching the seasonal figures above. For a comfortable swim, late spring through early autumn offers the warmest water, while year-round warmth makes short swims possible even in winter, provided one chooses appropriate sandy or reef-protected access rather than the marsh interior.
