Lake Superior's deepest point [4] on the bathymetric map. [1] Lake Superior has a surface area of 31,700 square miles (82,103 km 2), [7] which is approximately the size of South Carolina or Austria. It has a maximum length of 350 statute miles (560 km; 300 nmi) and maximum breadth of 160 statute miles (257 km; 139 nmi). [8]
Temperatures below −40 °F/°C occur somewhere in the region during most winters. The Midwestern Regional Climate Center climate summaries [26] record that Virginia has a mean annual temperature of 38 °F, with an average January low temperature of −6.2 °F (about −21 °C) and July high of 77.4 °F (25 °C). Precipitation there averages ...
The state is nearly 500 miles (805 km) from any large body of water (with the exception of Lake Superior), and temperatures and precipitation vary widely. It is far enough north to experience −60 °F (−51 °C) temperatures and blizzards during the winter months, but far enough south to have 114 °F or 45.6 °C temperatures and tornado ...

Because of the moderating influence of Lake Superior, summer temperatures are cooler, winter temperatures warmer, and the seasonal temperature difference is smaller than locations farther inland. With average highs of just below 70 °F (21 °C) in July and August, Grand Marais has the coolest summer temperatures of any weather station in Minnesota.
During the winter, areas along Lake Superior are considerably milder than inland. Winters in Lake Superior Provincial Park are very cold with significant snowfall. February is the coldest month in Lake Superior provincial Park with an average temperature of −12.5 °C (9 °F).
The island is known for its beaches on Lake Superior. Swimming is a less frequent activity because of the low water temperatures, although the beaches are a popular destination during the summer. The surface water temperature in the sheltered bay can rise to 70 °F (21 °C) while the water just off shore might remain at 50 °F (10 °C).
Specifically, the air temperature at an altitude where the air pressure is 850 millibars (85 kPa) (roughly 1.5 kilometers or 5,000 feet vertically) should be 13 °C (23 °F) lower than the temperature of the air at the surface. Lake-effect occurring when the air at 850 millibars (85 kPa) is much colder than the water surface can produce ...
