38 Line Water Temperature and Wetsuit Guide

(South Korea)

Today's 38 Line sea temperature is 22.0 °C.

Statistics for 01 Oct (1981–2005) – mean: 20.3 °C, range: 18.1 °C to 21.4 °C

Sunny with very warm air temperatures, feeling like 25 °C once we account for any wind. Sea temperatures (22 °C) warm too. Staying warm in the water won't be a problem in board-shorts, but wear at least a rash-vest to keep the UV off.

Below is a graph of Historical Sea Surface Temperature for 38 Line. 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 are on the same scale to enable comparison between locations around the world.

Actual sea surface water temperatures close to shore at 38 Line 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 38 Line.
