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
Castaway Cay, Disney’s private island in the Bahamas, offers classic tropical scenery with broad white-sand beaches and clear ocean shallows. Sea temperatures around the island vary through the year: in winter (December–February) surface waters typically sit around 22–24 °C, spring (March–May) generally warms to about 23–26 °C, summer (June–August) sees the warmest conditions near 26–29 °C, and autumn (September–November) commonly ranges from 25–28 °C. Short-term variations occur with weather, wind and currents, so on cooler days water can feel brisk near the lower end of those ranges while late-summer peaks approach the upper values. Overall, the water seldom drops far below the low 20s °C or rises much above the high 20s °C in typical seasons.
