*** 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
#Norfolk
Horsey Mere, one of the shallow broads on the Norfolk Broads, typically runs cool through much of the year. Typical seasonal surface temperatures range from about 1–6 °C (34–43 °F) in winter, 6–12 °C (43–54 °F) in spring, 15–22 °C (59–72 °F) in summer and 8–15 °C (46–59 °F) in autumn. There are no formal bathing facilities or lifeguards at the mere, and while informal swimming sometimes occurs, it is not actively promoted. Reed-lined margins, boat traffic, variable water quality and an occasional risk of algal blooms mean swimming is undertaken at people’s own risk and may be discouraged or temporarily restricted to protect both visitors and wildlife.
If you visit Horsey Mere you will find other attractions close by, including the iconic Horsey Windpump and the nearby Horsey Gap beach with its winter grey seal colony, plus the wider Broads network for boating and birdwatching. Local visitor centres and the Broads Authority publish up-to-date advice on water conditions and any seasonal restrictions, so check signage before entering the water.
