This ranked as the 52nd coolest May since 1895. The statewide average temperature of 59.3° was 1.9° below the 1991–2020 normal. Otherwise, May temperatures were cooler than normal, and rainfall sparse. Such was the case during the middle two weeks of May and at month’s end, with smoke from wildfires in western Canada frequently passing well overhead, followed by smoke from fires in Nova Scotia and a few in NJ. When the headline for this monthly report alludes to hazy May skies that were frequently overhead, you know it was a quiet period weather-wise across the Garden State. This was 0.43” below normal, however, it ranks as the 53rd wettest of the past 129 years (or 77th driest) due to the skewed nature of the distribution of monthly precipitation over this period. Both May and June averaged below normal, the first such back-to-back occurrence in NJ since April and May 2020.

The northern NJ climate division averaged 66.1° (-2.5°, 33rd coolest), the southern division averaged 68.9° (-2.5°, 36th coolest), and the coastal division averaged 68.2° (-2.3°, 45th coolest). The daily minimum averaged 56.6°, 3.0° below normal and was 35th coolest. The average daily maximum temperature of 79.0° was 2.0° below normal and ranks 40th coolest. This was 2.5° below the 1991–2020 mean and tied as the 36th coolest June since 1895. June temperatures across the state averaged 67.8°. However, not often do you find a month like this past June where one is left with their head spinning as smoke from near and distant wildfires darkened the sky, creating exceptionally unhealthy air quality, where growing drought concerns were quieted in most locations by late-month downpours, where two tornadoes touched down, and with temperatures averaging cooler than normal for the second consecutive month. There is rarely a month in New Jersey where something interesting, exciting, and different than normal doesn’t occur in the weather and climate department.
