July 2026 tied with July 2024 as the Earth's hottest month on record, a significant indicator of ongoing climate shifts. Scientists noted that the world's oceans also reached their highest temperatures on record for July, contributing to the overall warming trend. This result was anticipated by the prediction market, where the "1st hottest" outcome was a strong favorite, closing with 81% in its favor. The contiguous U.S. also experienced its hottest July on record, with an average temperature of 76.89°F, surpassing the previous mark set in 1895.
Background
The lead-up to July 2026's record-tying temperatures has been marked by a broader pattern of increasing global heat. Over the period we tracked this event, the market's odds for July 2026 being the hottest on record steadily climbed, reflecting growing scientific concern and observational data pointing towards extreme heat. The strengthening El Niño phenomenon has also been identified as a factor that could contribute to 2026 becoming the hottest year on record overall, setting the stage for these unprecedented monthly temperatures.
The precedent
- July 2026 tied with July 2024 as the Earth's hottest month on record.
