July on North Shore ran hot and cold

This year, our July temperatures were on a roller-coaster ride — some days extremely hot and some evenings downright chilly.

There were two significant heat waves (that gives us three for the summer so far). The first one lasted five days, from July 3 to July 7, hovering in the mid-90s. The second one was nearly five days long and gave us the hottest reading for the month — a blistering 100 degrees on the 19th! Not only were our temperatures high, but so was the oppressive humidity. On the other hand, we had a three-day period with morning temperatures in the chilly 50s.

Our rainfall gave us 3.27 inches, about normal for July. Most of the rain occurred on the 23rd and the 26th, giving us more than 21/2 inches in downpours. We had seven days with thunderstorms. However, none of them were particularly strong.

Summer is quickly passing by, and August has arrived. This month is usually our second-warmest of the year. At the beginning of the month, our daytime high temperatures usually climb into the 80s, while dropping to mid-60s by sunrise. There should be a noticeable decline in temperature toward month’s end with highs in the mid-70s and dropping to the low 60s by sunrise. Yes, but the warm temperatures will continue for those on their well-needed vacations.

When we check our records for the past 34 years, we experienced our highest August temperature of 101 degrees in 2006. On the other hand, our lowest temperature was 42 degrees in 1982.

Usually our rainfall for August is about 31/2 inches. However, we have had as much as 11.16 inches in 2011. On the other hand, we had a very dry August in 1995, when we received only 0.80 inches of rain.
