The Fourth of July marks the birth of our nation and it also is the unofficial start of the air conditioning season. State Climatologist Harry Hillaker says we’re entering what will likely be our warmest days.He says July is on average our warmest month of the year, averaging about two degrees warmer than August, the second hottest month. It’s not just the heat that causes problems in July. He says July usually has the highest humidity of the year. Hillaker says growing crops release moisture into the air and moisture coming up from the gulf make it humid. But Hillaker says we just over two weeks before the heat starts to subside.He says temperatures generally peak in Iowa around July 20th. Hillaker says the current indicators don’t point to any break from the typical July heat. He says his best guess would be we’d have a hotter than normal July, with near normal precipitation.
