Hottest Day of the Year – Average

June 27th, 2014 at 12:23 pm by under Bill's Blog, Weather

Hottest Day of the Year - from NOAA   Click on the graphic to enlarge or click here.   This is a map showing when you can expect to get the hottest day (warmest maximum temperature) of the year.  Here in Michigan, on average we get that between July 6 – 15.  The warmest average daily temperature (combination of high and low temperature) occurs around July 20 (so minimum temperatures are a fraction of a degree warmer in late July than in early July).  Look at the West Coast.  It takes time to warm up the deep ocean water, so the California Coast is most likely to see their hottest day in September.  Note that the same thing happens where the prevailing south wind comes off the Gulf of Mexico (S. Texas to Arkansas and east to the Mississippi River), which takes a while to reach it’s warmest (note the prime of hurricane season is in September and not in July).  On the other hand, the Big Bend Area of Texas on average sees their hottest afternoon of the year in the first half of June, before the “monsoon” brings are that is a bit more humid, a few more clouds and an occasional shower or t-storm.

Note – 5:55 pm Fri. -  grass fire near the campground at Holland State Park.  6:20 pm – firefighters have pretty much knocked the fire down.

    The best 3 months of the year are on their way :-) It looks like we will have a rainy weekend. I had some outdoor plans but I guess I will cancel. Have a great weekend anyway :-)

    What a beautiful day in Michigan and I’m hopping I can make my first ( summer ) trip to the fresh water ocean this weekend , weather permitting. I’m also going to have a little talk with the storm – shredder and see if I can work out a deal ( break bread ) to take Sunday – Tuesday morning off. Lol
