So far, Central Park's high today is 88°. Newark has reached 95°. Should Central Park fail to reach 90°, Central Park would record its shortest interval on record between dates where Newark reached 95° or above while Central Park failed to reach 90°. On June 29, 2025, Newark topped out at 95°, while New York City (Central Park) reached 89°. The existing shortest interval is 14 days from May 22, 2021 to June 5, 2021. JFK Airport and LaGuardia Airport have both reached 91° so far today.

I hit 92 here at 1 PM my second heatwave so far.

This June was miles hotter at Charlotteburg Reservoir than anything observed in 1980. Looks like in 1980, you could beat the heat by traveling an hour or so outside the urban heat island, while in 2025, the temperatures are much more uniform even way out in Passaic County.

The heat didn't start in June (at least not until the last week) and we're comparing sustained heat not just June but the entire summer.  1980 stands alone for July-August.

You can still beat the heat by traveling outside the UHI by the way, heat is relative, it will always be cooler outside of the UHI.

you're losing the forest for the trees. Since you love AI so much, here is an AI briefing on that summer:

 

AI Overview

 

 

The summer of 1980 was exceptionally hot, particularly in the Southern and Southeastern United States

.  

Key aspects of the 1980 heat wave:

• Duration and Intensity:
  • The heat wave extended from June to September in some areas, driven by a strong, persistent high-pressure system.
  • Dallas/Fort Worth experienced temperatures exceeding 100°F for almost six consecutive weeks.
  • Wichita Falls, Texas, recorded an unprecedented temperature of 117°F.
  • In Kansas City, Missouri, temperatures reached 100°F or more for 17 consecutive days.
  • Dallas-Fort Worth set numerous heat records, including the all-time highest temperature of 113°F (on June 26th and 27th) and the longest streak of days with high temperatures of at least 100°F (42 days).
  • The summer of 1980's average temperature in July for Dallas-Fort Worth was 92°F, making it the hottest month on record based on average temperature.
• Impact on the Population:
  • Extreme heat was a major factor in a significant number of deaths, with estimates ranging from 1,250 to 10,000 nationwide.
  • In Missouri alone, there were 389 heat-related deaths.
  • In St. Louis and Kansas City, deaths from all causes increased significantly in July 1980 compared to previous years without heat waves.
  • Elderly individuals and the urban poor were particularly vulnerable.
  • Many lacked air conditioning, making it difficult to cope with the extreme heat.
• Drought Conditions:
  • The high-pressure system inhibited thunderstorm development, leading to severe drought conditions.
  • The Ozarks, for instance, were under extreme drought conditions.
  • The dry conditions contributed to even higher temperatures.
• Economic Impact:
  • The heat and drought severely damaged crops and livestock, leading to estimated agricultural losses of around $20 billion.
  • Corn and soybean harvests were reduced by up to 50% in some areas.
  • Livestock suffered greatly, with thousands of cattle deaths reported.
  • Dairy cow milk production declined.
  • These losses impacted the economy, causing food prices to rise and contributing to the failure of some family farms. 

In summary, the summer of 1980 was characterized by a widespread and prolonged heat wave that caused significant human mortality, agricultural losses, and economic damage across the United States.

1980's historic nationwide heatwave is used as a textbook example of how lethal heat can be.

https://en.wikipedia.org/wiki/1980_United_States_heat_wave

 

The 1980 United States heat wave was a period of intense heat and drought that wreaked havoc on much of the Midwestern United States and Southern Plains throughout the summer of 1980. It was among the most destructive and deadliest natural disasters in U.S. history, claiming at least 1,700 lives.^[1] Because of the massive drought, agricultural damage reached US$20 billion (equivalent to $76 billion in 2024 dollars^[2]).^[3] It is among the billion-dollar weather disasters listed by the National Oceanic and Atmospheric Administration.

Causes

[edit]

The heat wave began in June when a strong high pressure ridge began to build in the central and southern United States allowing temperatures to soar to 90 °F (32 °C) almost every day from June to September. The high pressure system also acted as a cap on the atmosphere inhibiting the development of thunderstorm activity, leading to exceptionally severe drought conditions. The heat wave paused briefly when the decaying Hurricane Allen disrupted the prevailing weather pattern.

Effects

[edit]

The drought and heat wave conditions led many Midwestern cities to experience record heat. In Kansas City, Missouri, the high temperature was below 90 °F (32 °C) only twice and soared above the century mark (100 °F or 38 °C) for 17 days straight; in Memphis, Tennessee, the temperature reached an all-time high of 108 °F (42 °C) on July 13, 1980, part of a 15-day stretch of temperatures above 100 °F (38 °C) that lasted from July 6 to 20. In Indianapolis, Indiana on July 15, the temperature reached 100 °F (38 °C) for the first time since 1954.

In Dallas/Fort Worth, Texas, high temperatures exceeded 100 °F (38 °C) a total of 69 times, including a record 42 consecutive days from June 23 to August 3,^[4] of which 28 days were above 105, and five days above 110. The area saw 29 days in which the previous record high temperature was either broken or tied, including its all-time high when the temperature hit 113 °F (45 °C) on three consecutive days (June 26 and 27 at DFW Airport and June 28 at Dallas Love Field).

it's a park so there will be a difference

temperatures should not be measured in parks (and compared to airports)

you're losing the forest for the trees. Since you love AI so much, here is an AI briefing on that summer:

 

AI Overview

 

 

The summer of 1980 was exceptionally hot, particularly in the Southern and Southeastern United States

.  

Key aspects of the 1980 heat wave:

• Duration and Intensity:
  • The heat wave extended from June to September in some areas, driven by a strong, persistent high-pressure system.
  • Dallas/Fort Worth experienced temperatures exceeding 100°F for almost six consecutive weeks.
  • Wichita Falls, Texas, recorded an unprecedented temperature of 117°F.
  • In Kansas City, Missouri, temperatures reached 100°F or more for 17 consecutive days.
  • Dallas-Fort Worth set numerous heat records, including the all-time highest temperature of 113°F (on June 26th and 27th) and the longest streak of days with high temperatures of at least 100°F (42 days).
  • The summer of 1980's average temperature in July for Dallas-Fort Worth was 92°F, making it the hottest month on record based on average temperature.
• Impact on the Population:
  • Extreme heat was a major factor in a significant number of deaths, with estimates ranging from 1,250 to 10,000 nationwide.
  • In Missouri alone, there were 389 heat-related deaths.
  • In St. Louis and Kansas City, deaths from all causes increased significantly in July 1980 compared to previous years without heat waves.
  • Elderly individuals and the urban poor were particularly vulnerable.
  • Many lacked air conditioning, making it difficult to cope with the extreme heat.
• Drought Conditions:
  • The high-pressure system inhibited thunderstorm development, leading to severe drought conditions.
  • The Ozarks, for instance, were under extreme drought conditions.
  • The dry conditions contributed to even higher temperatures.
• Economic Impact:
  • The heat and drought severely damaged crops and livestock, leading to estimated agricultural losses of around $20 billion.
  • Corn and soybean harvests were reduced by up to 50% in some areas.
  • Livestock suffered greatly, with thousands of cattle deaths reported.
  • Dairy cow milk production declined.
  • These losses impacted the economy, causing food prices to rise and contributing to the failure of some family farms. 

In summary, the summer of 1980 was characterized by a widespread and prolonged heat wave that caused significant human mortality, agricultural losses, and economic damage across the United States. 

June 2025 was hot.  Newark was 2.5 degrees warmer than "normal" (the new norm), and had days over 100 degrees.  That is hot...

[winterwarlock]

t storms look like they will slide to my south..at least the initial batch

[donsutherland1]

Today became just the third day during the common recordkeeping period where Newark reached 95°, JFK and LaGuardia both reached 90°, but Central Park fell short of 90°. 2025 is the first year with two such days.

[donsutherland1]

Much of the region saw temperatures again reach 90° or above. Parts of the region will experience some heavy thunderstorms this evening and tonight. 

Generally warm weather will prevail through Saturday. New York City will see highs in the middle to perhaps upper 80s during this stretch. 

Excessive heat does not appear likely to return through at least the first week of July. However, there is somewhat less certainty than yesterday. There remains some potential for a shot of more significant heat during the July 6-8 period. 

The ENSO Region 1+2 anomaly was +1.0°C and the Region 3.4 anomaly was 0.2°C for the week centered around June 18. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +0.47°C and the ENSO Region 3.4 anomaly has averaged -0.03°C. Neutral ENSO conditions will likely continue through at least late summer.

The SOI was +2.65 today. 

The preliminary Arctic Oscillation (AO) was +1.127 today.

Yep, but it's just one month.  We'll see how the rest of the summer plays out and if it ranks with the all time greats. It has to continue on the trajectory of 2010 for it to do so.  Otherwise it's just a one month blip.

I have very high standards when it comes to summer heat.

These developments provide good examples of how the dense foliage has changed the relationship of Central Park relative to the City's other locations and Newark. The problem is cited in the NOAA's inventory of stations. Unfortunately, the problem is not addressed. Thus, Central Park becomes less representative of the City's actual climate and, instead, an experiment that demonstrates the cooling impact of trees.

Well, since nearly all other climate experiments and research has been squashed we should be happy ours will be ignored and be more likely to continue unimpeded.
