All About Lake SuperiorJeff Lynch
Lake Superior Weather
Predicting the weather any where is never an easy task. However, here on the North shore this is even more of a challenge. It is a challenge because of a phenomenon known as the “lake effect” which can drastically alter the predicted weather. In the summer the shore line of Lake Superior tends be about 10° cooler than if you are to drive about five miles inland up the ridge where it is about 10° warmer. The opposite effect happens in the winter time, the shore is 10° warmer and up the ridge is about 10° cooler. This is because water is slower to absorb and release heat than land. Storms can quickly become stronger than expected with the added moisture and speed of the wind traveling across the lake. This can create gale size waves and massive snow storms depending on the direction of the wind. Fog is another factor that is created because of the lake effect. Fog hides Duluth under a heavy blanket for 52 days in an average year by comparison, Minneapolis averages 11 day.
Lake Superior is responsible for at least 350 reported shipwrecks. The oldest of which was the SS Algoma and it sank on November 7th1885. The most famous of the ship wrecks the Edmund Fitzgerald just celebrated its 40th anniversary.
Here at Sawtooth Outfitters we sell a book called “The Night the Fitz Went Down” a great book to read if you are interested in learning more. Looking for a fun book to spice up the camp fire talk, “Haunted Lakes I and II” tells ghost stories from the Great Lakes.
