Website Weather Watching Options
Lake Superior, it is known, often creates its own weather.
Lake-effect snow is one outgrowth of the lake’s influence as is the 52
foggy days that Duluth, Minnesota, averages per year.
An easy online resource for marine forecasts can be found at
glin.net/conditions/superior.html and a Websurfer here can choose
from National Weather Service sites that offer Lake Superior
“Experimental Marine Forecasts,” “Marine Weather” or “Open Water Text
Forecast.”
These sites give near and open-water forecasts or warnings
issued through the Duluth or Marquette, Michigan, bureaus. Surface
water temperatures are here. Lake Superior averages 40°F year-round
surface water. In summer, some surface temps have been recorded to
70°F or so.
If you seek current weather conditions at about 50 towns
around the Lake Superior region, log onto our Website -
www.lakesuperior.com - to our “Regional News and Temps.” The towns are
listed alphabetically on the temps page.
Lake Notes
 Monitoring
of Lake Superior swimming beaches began again in May. Since monitoring
began consistently about four years ago, some beaches have regularly
recorded high bacteria levels. Studies are under way to map the major
bacteria sources as human, fowl or other animal. Throwing researchers a
curve, it was recently uncovered that e. coli - the bacteria counted to
determine the levels, may survive in the beach soils instead of only in
the guts of warm-blooded animals, as originally thought. This may skew
the test results. Studies continue this year.
