Yes, the reading is from the Airport where it peaked at 103°.

It did. Good catch.

100°+ Highs as of 1:30 PM:

As of 1 pm, the following areas have set new records: Atlantic City (101°); Poughkeepsie (99°), and Wilmington, DE (101°). The following locations have tied records: Manchester (95°) and Providence (98°). The following locations have also hit 100° and are approaching records: Harrisburg (100°), New York City-JFK Airport (100°), Newark (102°), and Philadelphia (100°). Central Park has reported a high of 98° so far. The statistical model (r2=0.941) based on the pre-tree overgrowth period has an implied 101° reading there.

Atlantic City has recently reached 100°. That ties its daily record from 1966.

Wilmington, DE has reached 98°. That ties the daily record that was set in 1941 and tied in 1966.

Such ridges are uncommon in the Eastern U.S. No disagreement on the location of such a ridge.

Unfortunately, that sensor is too close to the building. It's probably just 15-20 feet from the building. In general, its distance should be 4X the building's height.

It reached 100° at 11 am, on July 22, 2011. Here are the hourly readings up to the 108° all-time mark:

Select record high minimum temperatures (if they hold up through 1 am EDT):

For the U.S., one hasn't typically seen such heat domes during summers preceding strong/super El Niño events. Such events have been far more common in Europe and Asia. However, during 2015 (Pacific Northwest) and 2023 (July-August in the Southwest/South Central) such domes appeared. Whether these recent events suggest that things are changing in the warming climate (especially more expansive marine heatwaves) remains to be seen. A sample size of two is too small to draw firm conclusions.

Yes it did. It was a very impressive start to the heatwave there.

Select records from today. The heatwave will intensify tomorrow.

A short but severe heatwave will engulf the region into the start of the weekend. Already, parts of the region have experienced temperatures in the 90s. Through 5 pm, highs included: Albany: 94° Allentown: 97° Baltimore: 97° Boston: 92° Burlington: 93° Cleveland: 97° (old record: 95°, 1941 and 2002) Concord: 95° Detroit: 97° Harrisburg: 99° Hartford: 95° New York City: 93° Newark: 99° Philadelphia: 96° Poughkeepsie: 98° Reading: 99° Sterling: 97° (old record: 96°, 2012) Toledo: 99° (old record: 98°, 1931) Toronto: 97° Washington, DC: 96° White Plains: 93° Wilmington, DE: 96° At its height, the heat could rival that of early July 1966. Much of the region will likely experience its highest temperatures so this summer with maximum temperatures peaking in the 100°-105° range. Some locally hotter temperatures are possible. Most of the Mid-Atlantic and southern New England areas will see temperatures reach 100° or above during the height of the heatwave. Boston, Burlington, Philadelphia and Washington, DC could challenge their all-time records. The ENSO Region 1+2 anomaly was +3.1°C and the Region 3.4 anomaly was +1.8°C for the week centered around June 24. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +2.60°C and the ENSO Region 3.4 anomaly has averaged +1.37°C. The ongoing El Niño will continue to strengthen through the summer. The SOI was +1.11 today. The preliminary Arctic Oscillation (AO) was +1.312 today.

Dulles Airport has reached 96°. That ties its daily record from 2012. Many more records will fall in coming days in the Mid-Atlantic region.

Given NCEI's and the Central Park Conservatory's choice to permit tree overgrowth to persist at Central Park's ASOS, I've run the statistical model to see what Central Park's highest annual temperatures might have been had the statistical relationships to the 30-year period preceding the tree growth persisted (proxy for pre-tree readings). The estimated 102° reading in June 2025 would have set a new monthly mark. During 2015-2026, Central Park would likely have seen four to as many seven 100° readings. 2021 and 2025 had the highest likelihood that Central Park would have recorded one or more 100° or above readings. In an increasing number of cases, Central Park's reported highest temperature falls more than 1 standard deviation below the statistical estimate.

June 2026 ended with a monthly mean temperature of 73.4° in New York City. That was 1.4° above normal. Additional Notes: 1) Central Park's highest temperature was likely 97° on June 11-12 based on a statistical regression equation to compensate for tree overgrowth. 2) JFK Airport had an average high of 81.7° compared to Central Park's 81.4°. This is the largest margin by which JFK Airport's average June high was greater than Central Park's. The previous record and only such occurrence was in 2015 when JFK Airport's average high temperature was 0.03° higher than Central Park's mean high.

I'm glad he's on his way to recovering. What a shock, especially at his age.

June 2026 finished with a mean temperature of 73.4° in New York City. That was 1.4° above normal (2.0° above the 1981-2010 baseline). July will start with a severe heatwave. The heat could rival that of early July 1966. Much of the region will likely experience its highest temperatures so far this summer with maximum temperatures peaking in the 100°-105° range. Some locally hotter temperatures are possible. Most of the Mid-Atlantic and southern New England areas will see temperatures reach 100° or above during the height of the heatwave. Boston, Burlington, Philadelphia and Washington, DC could challenge their all-time records. The ENSO Region 1+2 anomaly was +3.1°C and the Region 3.4 anomaly was +1.8°C for the week centered around June 24. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +2.60°C and the ENSO Region 3.4 anomaly has averaged +1.37°C. The ongoing El Niño will continue to strengthen through the summer. The SOI was -10.83 today. The preliminary Arctic Oscillation (AO) was +1.196 today.

I recently posted about the issue here, as the trees will make it exceptionally difficult for Central Park to reach 100°. Last June, much of the region saw their hottest June temperatures on record, but not Central Park. In reality, based on the statistical relationships with JFK, LGA, and EWR, Central Park likely hit 100° on two days, including a June record 102°. I will run the numbers during the upcoming heatwave again. My guess is that those numbers will show 2 or perhaps even 3 100° days when the upcoming heatwave concludes. JFK's and LGA's average high temperature from 1996-2025 and 1991-2020 are well above their 1961-1990 average highs. In contrast, both sets of the more recent figures are cooler than their 1961-1990 figures for Central Park. As long-term climate figures are homogenized, the trees are a non-issue for 30-year and longer-term figures. Meanwhile, because daily data is not homogenized, daily records have been sacrificed. Even as this is the case, the news media still cites Central Park's figures as New York City's official data. In fact, during summer, Central Park's highs have become more a testament of the cooling power of trees than the City's actual readings.

Unfortunately, neither the Park nor NCEI are willing to address the issue. Long-term averages are homogenized to address such issues. Daily records are an afterthought.

"It's called 'summer'..."--CFACT policy analyst Meanwhile from Météo-France: The recent heatwave saw France record, on a national basis, three highest daily mean temperatures, four highest mean high temperatures, and four highest mean low temperatures on record. "Summer" doesn't describe this extraordinary climate change-driven heat. The reality from France: A warmer baseline climate makes hot patterns hotter. Key points from a recent World Weather Attribution rapid analysis: Across large parts of Western Europe, June is warming faster than any other month. In addition, daily maximum temperatures are warming faster than night time temperatures, though both are warming much faster than global warming. The hottest daily temperatures are warming at about triple the rate of global warming and night time temperatures at about twice the rate. Many capital cities are experiencing not only their hottest June 3-day period but also the hottest three-day period since 1950, according to the ERA5 dataset. However, due to global warming, these very high temperatures are now expected regularly during the summer months in many capitals. This means that a similar heatwave in June would have been about 3.5°C cooler during the day in 1976 and about 2°C cooler in 2003. The nighttime temperatures would have been about 2.4°C cooler in June 1976 and about 1.3°C cooler in June 2003. This June 2026 heatwave occurred under a circulation pattern broadly similar to historical analogues – Southerly Flow. However, a similar circulation pattern now produces significantly hotter temperatures than it did in the mid-20th century because the climate baseline has warmed. Key Points: 1) The heat was record-setting, not typical summer warmth 2) Human induced climate change contributed to the extreme nature of the heat 3) Interest-driven policy analysts are poor sources of weather/climate information; they seek to advance their employers' interests and some even resort to pushing misleading information to undermine public knowledge e.g., the flippant dismissal of the heat as "summer."
