Grand Haven Beach Weather Forecast

Thursday July 2

Partly sunny and warmer as we shift into holiday mode.  If your plans include Grand Haven for the 4th, you are in for some very good weather.  The surfing won't be happening, but almost all the other activities will be ideal.  Of course the beach weather couldn't be much better.  High temperature 70.  Low temperature 55.  Winds northwest 5-10 mph.  Sunrise 6:10am.  Sunset 9:26pm. 

Friday July 3

More sun and a touch warmer with light winds.  The morning could have a few clouds, especially areas to the east. Clearing skies out over the lake will forecast the better weather for the holiday weekend. Great weather to scope out a spot to set up camp for the 4th of July fireworks.  Not real hot this weekend, but some people like it that way.  High temperature 74.  Low temperature 59.  Winds north 5-10 mph.  Sunrise 6:11am.  Sunset 9:26pm. 

Independence Day- Saturday July 4

Sunny and mild.  Typical summertime conditions, but not real hot, at least not in terms of temperature.  Grand Haven will be in a festive mood with all of our summer guests and holiday activities.  Our Chamber of Commerce did a great job on ordering some comfortable weather.  High temperature 75.  Low temperature 61.  Winds south 6-12 mph.  Sunrise 6:11am.  Sunset 9:26pm.

Interesting Facts Of The Day

  The water temperature on June 28 at the south buoy in  the middle of Lake Michigan is 62 degrees, which is 7 degrees warmer from a week ago.  Although, the temperture  has dropped from 69 on Saturday with a steady wind that stirred things up.

Almost every year I can remember since the 1960's, we have had some pretty good waves for surfing the week of July 4th.  It may be that the water finally warms up close to the air temperature which is important for wave generation.

Because cold air is denser than warm air, it will tend to sink or stay near the surface.  While warm air is light and it will rise up in the atmosphere.  Therefore if one would measure the temperature at the surface, 25 feet and 50 feet there can be some significant temperature differences.  The local topography of an area can have a big effect on the temperature gradient, especially if the terrain includes a lake or mountain.
