Lake Michigan Water Temperatures Reach Earliest 80 Degrees

1003 PM CDT FRI JUL 6 2012 /1103 PM EDT FRI JUL 6 2012/
...OPEN WATER TEMPERATURES OF SOUTHERN LAKE MICHIGAN REACH 80
DEGREES...

THE WATER TEMPERATURE AT THE SOUTH BUOY ON LAKE MICHIGAN REACHED
80 DEGREES ON FRIDAY JULY 6TH...WHICH IS REMARKABLE WARMTH FOR THE
LAKE TO BEGIN WITH...BUT UNPRECEDENTED FOR THIS EARLY IN THE SUMMER
SEASON
. MONTHLY AIR TEMPERATURES HAVE BEEN ABOVE NORMAL FOR NINE
CONSECUTIVE MONTHS IN CHICAGO...AND THAT WARMTH HAS TRANSLATED
INTO WARM WATER TEMPERATURES ACROSS THE LAKE. THE PROLONGED HEAT
WAVE OF EARLY JULY OVER THE REGION FURTHER ESCALATED THE WARMING OF
THE LAKE AS WATER TEMPERATURES ROSE 10 DEGREES BETWEEN JULY 1ST AND
6TH!

THERE HAVE ONLY BEEN SIX PRIOR EPISODES SINCE 1981 WHERE THE
SOUTH BUOY WATER TEMPERATURE HAS REACHED 80 DEGREES. THESE WERE:
PERIOD NUMBER OF HOURS AT OR ABOVE 80 MAX WATER TEMPERATURE
-----------------------------------------------------------------
AUG 88 11 80
AUG 95 5 81
SEP 96 1 80
AUG 01 3 80
LATE JUL-AUG 10 13 80
JUL 11 1 80

ON FRIDAY...THE BUOY RECORDED TWO HOURLY READINGS OF 80 DEGREES.
THESE WERE THE EARLIEST 80 DEGREE WATER TEMPERATURES ON RECORD AT
THIS SITE. THIS SURPASSES THE PREVIOUS RECORD OF JULY 21ST SET BOTH
IN THE PAST TWO YEARS OF 2010 AND 2011.

WHAT IS EQUALLY AS REMARKABLE IS HOW FAR ABOVE AVERAGE THE WATER
TEMPERATURE IS
. LOOKING BACK AT THE AVERAGE JULY 6TH WATER
TEMPERATURE AT THAT BUOY SINCE 1981...THAT AVERAGE IS 63 DEGREES.
THE AVERAGE ON JULY 6TH 2012 WAS 78 DEGREES...15 DEGREES ABOVE
NORMAL!

Interesting. I didn't know that Lake Michigan ever got up to 80F.

I wonder if the lake being that warm can have some interesting weather effects.

I assume the 80°F lake temperatures are limited to shoreline regions?

^^ There is a surface temperature map in Cambium's third link. You have 80°F waters in the middle of the lake.

Must be pretty cool to live by a lake that partly freezes in the winter and goes up to 80°F in summer. Plus you have the advantages of sea without having to put up with a maritime climate.

I'd prefer a place like Nice on the Mediterranean. You have the advantages of sea without having to put up with a continental climate. Further north than Chicago, too.

Whoops. 84°F?! Looks like a typo. I should check the water temperature off NYC / Long Island.

US NODC Coastal Water Temperature Guide

74°F off of NYC, 72°F eastern LI. Still more time for it to heat up. Coast of eastern Maine is at 51°F!

Nice's climate won't offer such eerie landscapes:

Though no need to have a continental climate, oceanic lake Geneva has these from time to time.

Does anybody know of any major bodies of water that have reached over 100f? I know around the Arabian Gulf it gets into the 90s

Wow! Thanks for posting that info, I'll have to see if I can find the temp off TR or Manitowoc! 80 is a shocker, as kids we were always happy if it was 68 or 70, usually not until late July!

I remember my older sisters getting in trouble with my mom because they dared me to go in Lake Superior in June. I was a skinny little kid and it took blankets and a fireplace to warm me up.
