April was the fifth month of the past ten ranking in the top 10, joining July (#7), August (#1), January (#1), and February (#5). This ranks as the third warmest April on record (since 1895) only behind 20 for top honors. What can you say about a month that began with a swarm of tornadoes, finished with flooding rain, and in between, featured record heat, wildfires, and increasing drought concerns? Best to say that it was an odd one! Fitting this theme, the statewide average temperature of 55.4° was 3.9° above the 1991–2020 normal. The northern division averaged 57.8° (-2.1°, 50th coolest), the southern division 60.3° (-1.9°, 50th coolest), and the coastal division 59.6° (-1.4°, 63rd coolest). The average low temperature of 46.9° was 3.3° below normal, ranking 26th coolest. The average high temperature of 71.7° was 0.6° below normal, ranking 60th warmest and 68th coolest. This is the third smallest temperature difference on record between these two months.


Following the third mildest April on record, May was only 4.0° milder than the previous month. It was the coolest month compared to normal since January 2022.

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.
