Prediction markets put the probability at 76%: Will July 2026 be the 1st hottest on record. Currently, markets see this as likely (76% YES). How Europe's Extreme Heat Waves Have Impacted the Tour de France.
Global temperature records tumbled through the first three weeks of July 2026, feeding expectations that the month could rank as the july 1st hottest on record. According to The Economist, the surface temperature of Earth's tropical and mid-latitude oceans on July 14th was higher than on any comparable date in modern records — a pattern that held for every day so far this month and for nearly all of June. Europe has endured three heatwaves since May, with the continent's death toll running into the tens of thousands despite improved preparedness. The publication attributed part of the surge to "global dimming," as a cleaner atmosphere allows the planet to absorb more sunlight. [The Economist, Jul 16]
The heat has been geographically broad. NASA documented a heat dome broiling the Western U.S., with temperatures soaring on July 12, 2026 across the region. Days later, the National Weather Service forecast widespread readings of 95–105°F as a second wave pushed from the Southwest and Great Plains toward the eastern states, following an earlier scorch over the Fourth of July holiday. In Europe, the 2026 Tour de France — running July 4 to July 26 — logged an average temperature of 87.4°F through two weeks, far above the prior 78.6°F record set in 2022. Such sustained anomalies strengthen the case for a july 1st hottest on record ranking. [NASA Science, Jul 15]
The final week could prove decisive. Houston entered its hottest stretch of 2026 as a strengthening high-pressure dome parked over Texas, bringing consecutive days in the upper 90s and the city's strongest run yet at the 100-degree mark. Whether July 2026 is formally confirmed as the july 1st hottest on record will depend on datasets from agencies such as NASA, NOAA and Copernicus, which typically publish monthly analyses in early August. With ocean and land anomalies persisting near month's end, the remaining days offer little indication of a cooling reversal. [Houston Chronicle, Jul 20]
