More Rain, Less Wind Can Be Expected for Grand Junction in July
Not that this is necessarily a 'normal' summer in western Colorado, but based upon historical patterns we can expect more rain and less wind as we pass through the month of July.
According to WeatherSpark.com, if we receive at least .04 inches of rain it can be considered a wet day. The chances of having a wet day in July increase through the month from 11% to 21% by the time we get to the end of the month. However, considering the fact that the average precipitation for Grand Junction in July is .59 inches for the entire month, it's highly unlikely we will have more than one "wet" day in July. And considering the statewide drought, we may not even get to the half inch mark for the entire month.
In terms of average daily temperature, July is typically the hottest month of the year in Grand Junction with an average high of 93 degrees. By the time we get to August, we can expect the amount of rain we get to nearly double as the average daily high-temperature sinks to around 90 degrees.
I tend to complain about the wind a lot in Grand Junction, and I should have less to complain about as we go through July. At the beginning of the month, the average wind speed in Grand Junction is 7.4 miles per hour, decreasing to 6.1 miles per hour leading up to the calmest day of the year historically, August 10, when the wind speed is around 6.1 miles per hour. By contrast, the windiest day of the year in Grand Junction would be near tax time, April 11, when the average wind speed is about 8.3 miles per hour.
So there are lots of reasons to be optimistic about Grand Junction weather in July with moderating temperatures, increased precipitation, and diminishing winds. Only time will tell if history repeats itself.
