Lake Erie Water Temp vs 1998

The water temperature is still at dangerously cold levels. The lake water temperature lags behind the land temperatures a good 60-80 days in spring. Daytime temperatures in the suburbs can reach mid 60s or 70s yet the lake will stay very cold.  Water temperatures usually don't rise into the 60s until early June. Please, be very careful around the lake over the next two months.

We just came off of a big El Nino winter.  Milder temperatures with below normal snowfall. (we can very close to getting dumped on several times with large snowfalls. Those storms headed into New England). Will the lake water temperatures mirror the spring/summer of 1998, the end of the last big El Nino winter?

This graph show the water temperature in mid April as of this writing on the left.  The right box shows all of the Great Lakes during 1998 (after the last major El Nino).

The water temperature is already slightly above the 25 year average and in line with the April 1998 levels. Assuming we don't have significant runoff from heavy rainfall this spring through mid June along with average to slightly above normal temperatures, water temperatures should stay slightly above normal this summer if your heading to Edgewater or Cedar Point!

Here are the Lake Erie water temperatures in spring of 1998 with 30 year average in parentheses:

May 1:    52  (47)
May 15:  54  (52)
June 1:    64  (57)
June 15:  67  (62)
July 1:     71  (68)
July 15:   77  (72)(
July 21-23:  79 (Highest)  (73 on the 22nd)
August 1:    77  (74)
August 15:   77  (74)
September 1:   77  (73)
