Hornsea Water Temperature and Wetsuit Guide

The water temperature (7 °C) at Hornsea is very cold today and the windchill (4 °C) will make the air temperature seem even colder. You'll need a thick hooded winter wetsuit as well as neoprene gloves and neoprene boots and the cloudiness won't make it feel any warmer.

Below is a graph of Historical Sea Surface Temperature for Hornsea. This has been derived from analysis of two decades of oceanographic satellite measurements of nearby open water. We have calculated the average water temperature variation around the year as well as the extremes that have been observed on each date.

All of the graphs for the surf breaks presented on Surf-Forecast.com are on the same scale to enable comparison between locations around the world.

Hornsea water temperatures peak in the range 14 to 17°C (57 to 63°F) on around the 10th of August and are at their coldest on about the 18th of February, in the range 4 to 7°C (39 to 45°F). The warmest seasonal water temperatures at Hornsea in early to mid August lend themselves to a 4/3mm wetsuit or a 3/2mm suit and 3mm neoprene boots. The coldest water temperatures at Hornsea mean that you will need a flexible 6/5/4mm wetsuit or a well fitting 5/4mm wetsuit with gloves and 5mm neoprene booties and a hood to surf here in the third week of February.

Actual sea surface water temperatures close to shore at Hornsea can vary by several degrees compared with these open water averages. This is especially true after heavy rain, close to river mouths or after long periods of strong offshore winds. Offshore winds cause colder deep water to replace surface water that has been warmed by the sun. Air temperature, wind-chill and sunshine should also be considered before deciding on the kind of wetsuit needed to stay warm when surfing at Hornsea.
