This is the first decade with so many 90° days through the first 6 summers of the 2020s. The last cooler summer in NJ with most spots staying under 20 days was 2009. Have to go back to 1996 for Newark, Harrison, and SMQ to have under 10 days in the same season.

I finally made it to 90 today for the first time this week. It's not warm at night either, I turn off my a/c in the middle of the night. I know New Jersey has a radically different climate from the rest of us (in the winter and the summer) but for us the 1990s and 2010s (at least the first half) were much hotter. This decade the extreme heat is confined to areas away from the coast (except for that late June heatwave.) For us climate change is much more about higher humidity than it is higher summertime temperatures. Link to comment Share on other sites More sharing options...
LibertyBell Posted 4 hours ago Share Posted 4 hours ago 59 minutes ago, donsutherland1 said: This outcome is consistent with the warming summers that the region has been experiencing. Warming is measured by summer mean temperature. I constructed a chart for seven regional sites for the last 60 years and pegged the shading to the median value for each site. Don this matches my experience of 1983 and 2010 being the two hottest summers of my lifetime. I see Central Park was extremely hot in 1966 too (as was JFK). Can you extend this further back to the beginning of the climate history of JFK which is 1948 (I wish it was 1944 lol). I know 1949 and some of those 1950s summers were all extremely hot.

Tomorrow should be partly sunny. Clouds could become more numerous during the afternoon into the evening. We'll see how Saturday evolves. 1 Link to comment Share on other sites More sharing options...
donsutherland1 Posted 4 hours ago Share Posted 4 hours ago 20 minutes ago, LibertyBell said: Yes it's warmer but not necessarily hotter (as in more extremely hot.) I thought it would be useful to provide greater context to how things are evolving. Some of the most extreme heatwaves occurred during summers that are relatively cool by recent standards i.e., 1966 and 1977. Even as some of the extreme heat has not occurred, the tradeoff has been summer warmth that is greater and more persistent. Of course, there have been some hot summers that fit both criteria e.g., 2010. 2 Link to comment Share on other sites More sharing options...

Thanks Don, it looks like the 1948-1949 period was the hottest until 1983-84 and then 2010 which really stands out. Since then, hotter periods are happening more often although not to the extreme level of 2010. Don, is there any way to ascertain if 1944 would have been hotter than the 1948-49 period even though there were no instruments there in 1944? Did Newark or LaGuardia have data going back to 1944? I know Central Park does, I think they were hotter in 1944. Link to comment Share on other sites More sharing options...

Don, is there a way to rank summers like we rank winters aka the WSI? If so I'd like to rank summers in terms of extreme temperatures, duration of heatwaves, highest average temperature, highest mins, highest dewpoints, etc. Is there some way to factor in all the dimensions and derive a list of the top 10 summers that excel in all categories? Just based on intuition and my memory of the data I'd like to enter my top 10 in chronological order: Let's start with 1944 since that really stood out from that era. 1. 1944 2. 1948 3. 1949 4. 1953 5. 1955 6. 1966 7. 1977 8. 1983 9. 1993 10. 2010 If it wasn't confined to just 10 I would have added a few more-- 1980, 1988, 1991, 1995, 1999, 2002, 2005 Maybe we should do a Top 20 instead lol Link to comment Share on other sites More sharing options...

The description is at the bottom of the chart. 1966 was 11th (pulled down by its relatively cool mean temperature and cool highest minimum temperature). Summer 1948 isn't listed, because about half the days (46) had no data. 2025 is currently battling for the third spot, but it will likely fade lower given the forecast for the second half of August.

The higher humidity with dewpoints often over 75 helps heat it up overall since it carries more heat. So even though winds are onshore much of the time at JFK, it carries the higher dewpoints. 1 Link to comment Share on other sites More sharing options...

donsutherland1 Posted 1 hour ago Share Posted 1 hour ago Central Park and Islip had identical high and low temperatures for the first time since May 16th. During the 1991-2020 period, they had identical high and low temperatures on an average of 6.6 days per year. Link to comment Share on other sites More sharing options...

June & July 2025 came in it third place at 69.3F. Right now, I have August around 68.5F for a gridded statewide mean, which would yield a meteorological summer mean of 69.0F for the state. 2005 was a scorcher! With as hot as this summer has been, it's hard to believe it was more than 1F warmer. That's huge for a statewide average. 1 Link to comment Share on other sites More sharing options...
