Water Temperature: Daily Trends, Historical Records, and Forecast

✅ As of today, the minimum water temperature is above 82°F (28°C). This is very warm water, which may feel almost hot to most people. Swimming in such conditions is perfect for those seeking relaxation and comfort in the water. These waters are often preferred for relaxation in hot weather, as the water temperature does not cool the body significantly. However, it is important to remember that in such warm waters, caution is necessary, as prolonged exposure without rest can lead to overheating.

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.

Annual Water Temperature Trend

Cape Charles sits on the Virginia Eastern Shore along the sheltered waters of the Chesapeake Bay, offering a mix of shallow coves, sandy shores and a small-town harbor atmosphere. Because the town faces the bay rather than the open Atlantic, surface water temperatures tend to be moderated but can respond quickly to air temperature, sunlight and wind. Over the course of a typical year, winter surface temperatures commonly range from about 1 to 6 °C, rising through spring to roughly 6 to 16 °C by late May. Early summer brings warmer conditions of roughly 18 to 23 °C in June, with peak summer surface temperatures in July and August usually between 22 and 28 °C, occasionally reaching the upper end in shallow, protected areas. By September and October the waters cool to about 15 to 20 °C, with further drops into late fall. Local tides, runoff and seasonal weather patterns create year-to-year variation in these approximate ranges.
