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
Saint James City sits on the Gulf side of Pine Island in southwest Florida and experiences the warm subtropical waters typical of this region. Sea surface temperatures vary through the year, with winter months commonly around 18–22°C, spring warming into the low 20s, roughly 21–26°C, and summer months often reaching the upper 20s to around 31°C. Autumn generally remains mild, with temperatures commonly between 24–29°C before the water cools again. These seasonal patterns reflect the shallow, sheltered nature of the waters around the island, which heat and cool more quickly than deeper offshore water, so local temperatures can feel slightly warmer in the shallows and cooler during onshore cold fronts.
