A shower or thundershower is possible tonight into early tomorrow. Afterward, tomorrow will be pleasantly warm with highs in the lower to perhaps middle 80s. Some showers are possible tomorrow night and then again Friday night or Saturday. A warming trend could commence on Sunday. The guidance increasingly suggests that hot weather could return to conclude June and start July. The ENSO Region 1+2 anomaly was +3.0°C and the Region 3.4 anomaly was +1.7°C for the week centered around June 17. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +2.42°C and the ENSO Region 3.4 anomaly has averaged +1.22°C. The ongoing El Niño will continue to strengthen through the summer. The SOI was -18.28 yesterday. The preliminary Arctic Oscillation (AO) was +0.424 today. Based on sensitivity analysis applied to the latest guidance, there is an implied near 94% probability that New York City will have a warmer than normal June (1991-2020 normal). June will likely finish with a mean temperature near 73.4 (1.4° above normal). Supplemental Information: The projected mean would be 2.0° above the 1981-2010 normal monthly value.

Today was another day of furnace-like heat in France, Jersey, and the UK. The extreme heat will shift eastward over the next few days.

The Paris-Montouris station, for which records go back to 1872, has recorded its first case of two consecutive 40°C (104°F) or above days. Paris-Jardin du Luxembourg topped out at 41.2°C (106.2°F). Jersey (Maison St. Louis: 39.3°C/102.7°F) and Switzerland (Basel: 38.0°C/100.4°F) set national all-time records. The UK (Merrifield: 36.7°C/98.1F) set a national June monthly record.

The official announcement from Météo-France: Translation: June 24, 2026 France has just experienced its hottest day ever recorded. Across the country, the average temperature over 24 hours reached 30°C, exceeding the 29.9°C measured... the day before, which was already the hottest day ever recorded since measurements began in 1947.

It showed up on the list of all-time records, so I noted it.

Tomorrow and Friday will be pleasantly warm days with highs in the lower 80s. Some showers are possible tomorrow night and then again Friday night or Saturday. A warming trend could commence during or after the next weekend. Some of the guidance suggests that hot weather could return to conclude June. The ENSO Region 1+2 anomaly was +3.0°C and the Region 3.4 anomaly was +1.7°C for the week centered around June 17. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +2.42°C and the ENSO Region 3.4 anomaly has averaged +1.22°C. The ongoing El Niño will continue to strengthen through the summer. The SOI was -22.92 yesterday. The preliminary Arctic Oscillation (AO) was +0.406 today. Based on sensitivity analysis applied to the latest guidance, there is an implied near 91% probability that New York City will have a warmer than normal June (1991-2020 normal). June will likely finish with a mean temperature near 73.5 (1.5° above normal). Supplemental Information: The projected mean would be 2.1° above the 1981-2010 normal monthly value.

Paris, like NYC, has multiple sites. I referenced one such site.

I agree. Indeed, one location in coastal France beat its all-time record that was set just yesterday by 4.0C (7.2F).

"Intense heat destroys even the temper of steel..."-George Prentice. It was that kind of day in France, Spain, and the UK today. In Paris, no relief was found under the trees of Jardin du Luxembourg as the mercury rose to 42.2C (108.0F). The UK recorded its hottest June temperature on record with a high of 36.1C (97.0F) at Gosport. As a result of the ongoing heatwave, which is France's worst June heatwave on record, 2026 already accounts for the second most all-time record high temperatures for any calendar year.

Those were monthly records. 13 all-time records were broken at stations with 80+ year climate records.

Any showers will depart this evening. It will turn somewhat warmer for tomorrow through Friday will likely see highs in the lower 80s. Some showers are possible as a warm front moves across the region on Friday or Saturday. A warming trend could commence during or after the next weekend. Some of the guidance suggests that hot weather could return to conclude June. The ENSO Region 1+2 anomaly was +3.0°C and the Region 3.4 anomaly was +1.7°C for the week centered around June 17. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +2.42°C and the ENSO Region 3.4 anomaly has averaged +1.22°C. The ongoing El Niño will continue to strengthen through the summer. The SOI was -19.68 yesterday. The preliminary Arctic Oscillation (AO) was +0.369 today. Based on sensitivity analysis applied to the latest guidance, there is an implied near 90% probability that New York City will have a warmer than normal June (1991-2020 normal). June will likely finish with a mean temperature near 73.7 (1.7° above normal). Supplemental Information: The projected mean would be 2.3° above the 1981-2010 normal monthly value.

It was a surreal day in France. The air was "a furnace breath." The "heatquake" toppled, shattered, and demolished more than 100 all-time high temperature records. June 2026 has surpassed June 2019 for setting the most all-time record highs in the month of June.

Very tragic. Unfortunately, there will almost certainly be many more fatalities across Europe as the heat dome expands.

Through 6 pm, rainfall amounts included: Bridgeport: 0.78" Islip: 0.07" New York City: 0.58" Newark: 1.00" White Plains: 0.50" Showers and periods of rain will likely continue into early tomorrow. Some locations could experience a thunderstorm. A general 0.50"-1.50" rainfall is likely. Some locally higher amounts are possible. Following the storm, readings will reach the middle and upper 70s tomorrow. Wednesday through Friday will likely see highs in the lower 80s. Some showers are possible as a warm front moves across the region on Friday. A warming trend could commence during or after the next weekend. Some of the guidance suggests that hot weather could return to conclude June. The ENSO Region 1+2 anomaly was +3.0°C and the Region 3.4 anomaly was +1.7°C for the week centered around June 17. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +2.42°C and the ENSO Region 3.4 anomaly has averaged +1.22°C. The ongoing El Niño will continue to strengthen through the summer. The SOI was -19.68 today. The preliminary Arctic Oscillation (AO) was +0.029 today. Based on sensitivity analysis applied to the latest guidance, there is an implied near 90% probability that New York City will have a warmer than normal June (1991-2020 normal). June will likely finish with a mean temperature near 73.8 (1.8° above normal). Supplemental Information: The projected mean would be 2.4° above the 1981-2010 normal monthly value.

It will be interesting to see how this ultimately plays out. I suspect that the Sonoran Desert has yet to see its highest temperatures this summer, even if the forecast values for this week verify.

France sizzled under a heat dome that felt more like a fire dome today. More than 300 locations reached 40C (104F) or above, 123 all-time records were set, and an additional 453 monthly records were set.

All-time temperature records are again falling in France. As of early this afternoon (local time), 2026 had produced the tenth most all-time records for any calendar year (and second most in June). By the close of today, 2026 will very likely rank 6th highest. Seven of the ten years with the most all-time records have occurred since 2015.

IMO, the big issue right now is the disagreement between the JAMSTEC (much cooler ENSO Region 1+2 anomaly relative to the Region 3.4 anomaly) and other guidance e.g., ECMWF seasonal (similar or warmer Region 1+2 anomaly relative to the Region 3.4 anomaly). We're in June. What is fairly certain is that a strong/super ENSO event is likely. In addition, the Region 1+2 anomaly has been running higher than the Region 3.4 anomaly into early June. Given the forecast strength of the ENSO, strong or persistent blocking would be helpful if one is looking to maximize wintry prospects. Whether this will be more like 1877-78, 1972-73, 1982-83, or 1997-98 remains to be seen, especially this far out.

Tomorrow and Tuesday will be cooler days. Rain is likely on tomorrow into tomorrow night. Some locations could experience a thunderstorm. The potential exists for a general 0.50"-1.50" rainfall. No excessive heat appears likely through at least June 25th. A warming trend could commence during or after the next weekend. Some of the guidance suggests that hot weather could return to conclude June. The ENSO Region 1+2 anomaly was +2.6°C and the Region 3.4 anomaly was +1.3°C for the week centered around June 3. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +1.95°C and the ENSO Region 3.4 anomaly has averaged +0.98°C. The ongoing El Niño will continue to strengthen through the summer. The SOI was -5.98 yesterday. The preliminary Arctic Oscillation (AO) was +0.096 today. Based on sensitivity analysis applied to the latest guidance, there is an implied near 87% probability that New York City will have a warmer than normal June (1991-2020 normal). June will likely finish with a mean temperature near 73.9 (1.9° above normal). Supplemental Information: The projected mean would be 2.5° above the 1981-2010 normal monthly value.

The heat intensified in France today. All-time temperature records began melting from the relentless heat. Eleven locations set new all-time marks and 112 reached 40°C (104.0°F) or above. Paris-Jardin du Luxembourg reached 38.3°C (100.9°F), narrowly missing its June monthly record that was set on June 19th (38.4°C/101.1°F).

So far, 16 locations in France have reached 40°C (104°F) or above today in an ongoing climate change-enhanced extreme heatwave. Pissos has hit 41.5°C (107°F). While one waits for the final numbers from today and coming days that will rank this heatwave as among the worst in French and western European climate history, I created a digital artwork "It's A Crazy World" to symbolize humanity's unwillingness to confront the cause of ongoing climate change. A burning globe stands before a background of climate stripes, transforming scientific evidence into a stark visual record of the world’s ongoing warming. Europe glows with dangerous heat, while a thermometer planted over France reads 40°C. In the lower left, fossil fuel infrastructure appears almost toy-like against the scale of planetary disruption: small in form, but immense in consequence. At the right, a pale sculptural figure (detail from Jean-Baptiste Carpeaux’s "Ugolino and His Sons" that I photographed at the Metropolitan Museum of Art) evokes humanity’s mounting suffering under the pressure of a hotter world. This work confronts one of the central absurdities of the modern age. The evidence is overwhelming and unequivocal. The burning of fossil fuels is driving anthropogenic greenhouse gas warming, and that warming is increasing the frequency and severity of extreme heatwaves. Yet humanity continues to extract, burn, subsidize, and consume the very fuels accelerating the crisis with seeming indifference to the harm it is inflicting on the world and its ecosystems. The contrast between beauty and terror is deliberate. The climate stripes are visually elegant, but they record a destabilizing planet. The glowing continents are dramatic, but they signify real risk. The sculptural body, drawn from an image of suffering, gives human form to what can otherwise seem abstract. The quote from a young French climate activist anchors the work in moral urgency, insisting that the crisis is not distant, theoretical, or merely environmental. It is already a question of life and death. "It’s A Crazy World" is about knowing and continuing destructive business as usual anyway. It asks viewers to consider the madness of a civilization capable of measuring its own danger with precision while still choosing to feed the fire.

Absolutely. This ongoing experiment is demonstrating the cooling power trees provide in a warming world.

Through today, JFK Airport has had an average high temperature of 82.50° while Central Park's average maximum temperature is 81.85°. The only June that saw JFK Airport record a higher average high temperature than Central Park was June 2015 when JFK Airport edged Central Park 78.53° to 78.50°.

The weekend will conclude with fair and warm conditions. Highs will mainly reach the lower 80s. Monday and Tuesday will be cooler days. Rain is likely on Monday into Monday night. The potential exists for a general 0.50"-1.50" rainfall. No excessive heat appears likely through at least June 25th. A warming trend could commence during or after the next weekend. The ENSO Region 1+2 anomaly was +2.6°C and the Region 3.4 anomaly was +1.3°C for the week centered around June 3. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +1.95°C and the ENSO Region 3.4 anomaly has averaged +0.98°C. The ongoing El Niño will continue to strengthen through the summer. The SOI was -5.98 today. The preliminary Arctic Oscillation (AO) was +0.112 today. Based on sensitivity analysis applied to the latest guidance, there is an implied near 82% probability that New York City will have a warmer than normal June (1991-2020 normal). June will likely finish with a mean temperature near 73.7 (1.7° above normal). Supplemental Information: The projected mean would be 2.3° above the 1981-2010 normal monthly value.

Unfortunately, that's the case. Paris-Jardin du Luxembourg hit 101° today, surpassing the monthly mark of 100° set just yesterday. Even higher temperatures are likely during the weekend.
