Water Temperature: Daily Trends, Historical Records, and Forecast
⚠️ As of today, the minimum water temperature ranges from 54°F (12°C) to 60°F (15°C). The water is significantly warmer, and swimming becomes possible for most people. However, caution may still be required for prolonged stays in the water, as extended exposure can cause discomfort. This is a suitable temperature range for short swims and for those accustomed to cooler water. For more comfortable swimming, it is recommended to use proper gear. It is important to note that these swimming tips and recommendations apply only in good weather. When the air temperature is below 68°F (20°C), and sometimes even below 77°F (25°C), swimming can be unpleasant even with relatively high water temperatures.

*** Forecast - Our water temperature forecast
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
The River Thames at Grays, being part of the tidal estuary near the sea, experiences water temperatures that mirror coastal conditions. The winter minimum typically ranges from about 6 to 9∘C (43 to 48∘F), while the warmest part of the summer sees temperatures rise to approximately 16 to 19∘C (61 to 66∘F), usually peaking in August or September. This variation, influenced by the North Sea, ensures the water remains significantly cold for much of the year, even when the air is warm.
Swimming in the River Thames in the Grays area is strongly advised against and generally prohibited due to safety concerns. The Port of London Authority enforces restrictions because the river here is a busy, commercial, deep-water channel with very strong currents and fast-moving tides that pose a high risk of drowning. Furthermore, the water quality is poor, carrying risks of illness from pollution, particularly following heavy rainfall. Instead of swimming, visitors can explore local landmarks like Tilbury Fort, a historic artillery fort, or the Chafford Gorges Nature Park, a scenic reserve created from former chalk quarries.
