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.

Location & Local Information
Gravesend, a town in Kent on the south bank of the River Thames, lies where the tidal river widens into its estuarial lower reaches. In this part of the Thames temperatures follow the seasonal rhythm influenced by both freshwater flow and tidal mixing. In winter the water often stays around 6–8 °C (43–46 °F), slowly warming to roughly 10–13 °C (50–55 °F) by spring. During the height of summer—July and August—surface temperatures typically rise to around 17–19 °C (63–66 °F), although strong tidal currents and shifting depths keep that warmth less consistent than in calmer inland waters. As autumn arrives, the water cools again to about 12–14 °C (54–57 °F).
Swimming in the Thames by Gravesend is legally permissible but considered challenging and best suited for experienced open-water swimmers. The river here is subject to significant tidal movement, boat traffic, variable underwater terrain and occasional sudden currents, all of which require caution. Many people instead enjoy riverside strolls, kayaking or ferry rides from the Town Pier. Nearby attractions such as the historic Gravesend Town Pier, Windmill Hill lookout and riverside gardens offer pleasant alternatives to diving in while still enabling enjoyment of the riverside setting and the broad Thames estuary.
