Houghton Lake
Period of Record: 1919-Present

Footnote: the heat records, for Houghton Lake, are impressive, especially before 1950. That is because temperatures were originally recorded southwest of the Lake. However, with observations now being taken at the airport, which is northeast (downwind) of the Lake, it is likely that many of these records will never be challenged due to the Lake's cooling influence.

So far, in 2012, Houghton Lake has reached, or exceeded, 90° on 10 days.
