(Lake Michigan, USA)

Today's Zion sea temperature is -1.1 °C.

Statistics for 15 Jul (1981–2005) – mean: 18.5 °C, range: 15.2 °C to 21.7 °C

Don't be deceived by the very warm air temperatures because the water temperature at Zion will be close to freezing today. Surfers will need a thick winter wetsuit, a neoprene hood, wetsuit gloves and neoprene boots. Feeling much more pleasant out of the water than in the sea today.

Below is a graph of Historical Sea Surface Temperature for Zion. 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.

Zion Water Temperature Graph

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.

Zion sea water temperatures peak in the range 19 to 24°C (66 to 75°F) on around the 14th of August and are at their lowest on about the 1st of March, in the range 3 to 4°C (37 to 39°F). Zion sea water temperatures are warmest in mid August. Surfers should use a 2mm long sleeve shorty or a 3/2mm spring wetsuit if the wind is up. The lowest sea water temperatures at Zion 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 at the beginning of March.

Actual sea surface water temperatures close to shore at Zion 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 Zion. Refer to our detailed weather forecasts for this information.

 

FEATURE UPDATE: we now show red swell icons for 'open sea' swells that are travelling in an unfavourable direction for the surf break. In places, these swells may still wrap around coastlines and produce smaller waves at some breaks. They are also significant for windsurfers and other water users that tend to venture further off-shore.
