Summary
The second week of June 2025 was wetter and cooler than the week before at Greg’s Weather Center in South Plainfield, NJ. There were three days of measurable rainfall that accounted for nearly an inch of rain. There were two days of 80° weather with one of those days falling just short of 90.
There have been 15 days of 80° weather at GWC, but there hasn’t been a 90° day yet. At this point a year ago, there were 20 days with high temperatures of at least 80 degrees and no 90-degree days yet. Rainfall so far this month is running behind the average with only a little over an inch.
The barometer was mostly steady this week with no real significant rises or falls in pressure. There were no big storms or severe weather this past week. There was a larger presence of haze in the skies over GWC this week. Smoke from Canadian wildfires have pushed eastward resulting in the haze.
The increase in smoke and haze coupled with increased heat and humidity produced air quality alerts around the Garden State and the New York City metropolitan area on Wednesday and Thursday. The most uncomfortable day was Thursday with many locations hitting 90° for the first time while dew points climbed into the upper 60s.
