Great Lakes Still Very Cool

Lake Michigan Water Temperature   This graph (from NOAA Coastwatch) shows the water temperature of Lake Michigan for the past 5 1/2 years.   This is the coldest that we have seen Lake Michigan in August in recent years.   The average surface water temperature of Lake Michigan is roughly 11° F cooler than it was in the first week of August in 2012.  You can check out the temperature graph for Lake Superior (which looks to be about 15° cooler than 2012), Lake Huron, Lake Erie and Lake Ontario.  Here’s the current Lake Michigan beach water temperatures.

    Yeah the lakes are going to be cool all year because of the polar vortex that we had (once every thirty years). The warm weather recently will do very little to warm the lake.

      And 2012 was a special year btw so we can’t compare it to that ;)

    Also gonna make for a cooler fall and winter since artic air will not be moderated as much if the water is already cool.

      Depends on how “cold” the air coming over the lake is. But there could be less cloud cover at night and that could lead to an earlier frost in the fall.

  3. Well if these lakes remain “cold” through the rest of the year and are cooling quicker in the winter, wouldn’t that mean less lake effect since they may freeze over faster?

    1. SlimJim NW GR (1) says:

      It could but remember Lake Superior is always colder then Lake Michigan and there is a lot of lake effect that comes off of Lake Superior. There is a lot more then just lake water temp that affects lake effect.

        There is also colder air over Lake Superior in the winter, so it kind if cancels out. But true, it is only one factor. (A very important factor though)

        1. Good point Nathan and very true slim there are more factors that come into play. Guess its a wait and see

    Lk Michigan remains among the coldest relative to average.

    Lake Huron, in comparison, has been average to only a few degrees below average all year:

    Thanks for the lake updates. Read an article in Christian Science Monitor on Lake Erie algae bloom. They referred to the mysterious circumstance of the bloom, but still offered speculation that warming and “climate change” were again at work. Apparently, they have short memories of the 2014 cool weather pattern and also cannot access Great Lakes temperature data.

      Lake Erie spent most of June with above average water temperature.

      Then it hovered around average and now it’s slightly below.
