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
Average Monthly Water Temperature
Annual Water Temperature Trend
Miami Beach, situated on a barrier island off the coast of southeastern Florida, benefits from a subtropical climate that keeps its Atlantic waters relatively warm year-round. Typical sea-surface temperatures vary with the seasons: in winter (December–February) waters usually range from about 20 to 24°C, spring (March–May) warms to roughly 22 to 26°C, summer (June–September) sees the warmest conditions often between 27 and 31°C, and autumn (October–November) generally holds around 25 to 29°C. These values can shift slightly from year to year, and occasional cold fronts can produce shorter periods of cooler water, while late-summer warmth and localized currents may push temperatures toward the upper end of those ranges.
