July In a Nutshell: Cool & Damp - 08/01/13
Can you believe we're already into the month of August? What happened to July? Last month will go down in West Michigan as a cooler and wetter than average. Following in the footsteps of June, maximum temperatures were a couple of degrees below the climatological (30 year) norm. Last month's high averaged 81.4, down 2.6 from the long-term average. The minimum temperature for July averaged 62.4, which is less than half a degree off the long-term average.
15 of the 31 days had cooler than average max temperatures. If not for the nine day stretch of warmer than average temperatures in the middle of the month -- including a stretch of five straight 90 days -- the month would have been even more abnormally chilly.
The contrast to July 2012, which contributed to one of the hottest summers on record in West Michigan, is striking. Consider: last month, we had high temperatures in the 70s nine days, and one day, the high was in the 60s (July 28, 66)! In July 2013, we had ZERO days with highs in the 70s; the coolest max temp was 81. Additionally, the highest max temp last month was 94 (July 19th). The average high temperature for July 2012 --AVERAGE -- was 91.6.
Here are some other details from last month's weather: we picked up 3.88'' of rainfall, which is slightly above average; we saw about 61% of available sunshine, down from the normal amount which is just about 70%, and significanly down from last year's whopping 78%.
