Was July the hottest July on record?


It depends on who you ask. NOAA says yes, Copernicus says no. 

NOAA said July 2024 was the 14th consecutive month of record-high global temperatures. The global land-only July temperature was also warmest on record at 1.70°C (3.06°F) above average. The ocean-only temperature was second-warmest at 0.98°C (1.76°F) above average, ending a streak of 15 consecutive monthly record highs from April 2023 to June 2024, according to NOAA. 

According to Copernicus, the daily global average temperature reached 17.16°C and 17.15°C in ERA5 on 22 and 23 July. But July 2024 overall was the second warmest month globally and the second warmest July in the ERA5 data record of the European Union’s Copernicus Climate Change Service. It was just 0.04°C lower than the previous high set in July 2023.

The World Meteorological Association summed it up as July was one of the hottest - if not the hottest - month on modern record, and the world’s hottest day was registered. You wouldn't have known it in Ireland. 

At least the SST has not been setting records. But there's a hurricane barreling towards Bermuda and potentially here afterwards. That's a pattern we used to see in the past.
