Maine Beach water temperatures peak in the range 17 to 20☌ (63 to 68☏) on around the 8th of August and are at their lowest on about the 1st of March, in the range 2 to 3☌ (36 to 37☏). We have calculated the average water temperature variation around the year as well as the extremes that have been observed on each date.Īll of the graphs for the surf breaks presented on are on the same scale to enable comparison between locations around the world.
This has been derived from analysis of two decades of oceanographic satellite measurements of nearby open water. This layer doesn’t provide real time temperature, but it's a close approximation that can be used for recreational purposes.Below is a graph of Historical Sea Surface Temperature for Maine Beach. You can use the satellite daily averaged sea surface temperature to get an approximate temperature for beaches and other coastal areas that aren’t near a buoy or tide station. How can I see what the water temperature is closer to me? More on cold water survival There are no buoys or tide stations near my beach. This can possibly extend your survival time. (Heat Escape Lessening Posture) if alone, or huddle with others. Swimming or treading water will greatly increase heat loss and may limit your range to less than one-half mile. The body quickly surrenders its heat to cold water, and chilled blood can impair the heart and brain. Hypothermia, a subnormal body temperature, can occur in waters with cold or even moderate temperatures. Hot and cold water are relative, however, even in the summer, prolonged immersion in water temperatures below 70° Fahrenheit can produce hypothermia. This can be caused by a persistent offshore wind blowing the warmer surface waters away from the shore. It could be due to a phenomenon known as upwelling, which occurs when displaced surface waters are replaced (upwelled) by colder, deeper waters. Why is the water at the beach sometimes cold on warm summer days? Yes, nearshore water temperatures are more susceptible to the influence of river runoff, higher cooling and heating rates, continental air masses, near-shore ocean currents, and upwelling effects. Can water temperatures differ between nearshore and offshore sites at the same latitude? There's no real optimal temperature, but many people feel “comfortable” swimming in water that is 70° to 78° Fahrenheit. Please note that some stations have been operating for decades, while others are newer.įrequently Asked Questions What is the best water temperature for swimming in the ocean?
Because observations may vary with the station's status, a weighted-average method was used, based on the number of temperature observations available in a given month. * All of the historical data available for each station was used to calculate the water temperature averages listed in the "Table of Monthly Averages". * When viewing the OISST layer, note that this is a daily average sea surface temperature and not real-time water temperature. * Use the near real-time water temperature data with discretion ~ may contain errors. It is a blended SST file of buoy, ship, Argo, and satellite observations.
