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.

During midsummer—particularly in July and August—the water often reaches 17–19°C (63–66°F), with the estuary’s shallow sections heating slightly faster on sunny days.

Swimming in the River Exe around Exmouth is both possible and popular, especially along the sheltered estuary beaches and at the river mouth where it meets the sea. The water is generally clean, and tides help renew it regularly, though swimmers must be cautious of changing currents.
