Why This Could Be Earth’s Warmest August Yet — And It’s Not Close

Early tracking data shows the month running far above previous record years, following a summer already stacked with global heat milestones
New Delhi, August 18, 2026 — Halfway through August, global temperature trackers are flashing red. Climate-data watchers monitoring daily reanalysis figures say the month is running well ahead of the pace set by 2023 and 2024 — the two hottest Augusts ever recorded — prompting comparisons to a summer that has already broken records almost every month it’s touched.
Full, verified global rankings for August won’t be published until early September, when NOAA’s National Centers for Environmental Information, NASA, and the EU’s Copernicus Climate Change Service release their monthly climate bulletins. Until then, real-time estimates come from daily reanalysis datasets like ERA5, which blend satellite, ship, aircraft, and weather-station data to produce near-real-time global averages.
Those preliminary daily figures are why climate trackers are already calling attention to August 2026 — even before the official numbers land.
The month didn’t come out of nowhere
This isn’t an isolated spike. July 2026 was already confirmed as a record-breaker: it tied with July 2024 as Earth’s hottest month since record-keeping began in 1850, according to Yale Climate Connections. The same analysis found global ocean surface temperatures were the warmest on record for July, while global land temperatures ranked third-warmest.
Copernicus’s own account of July was slightly more conservative but pointed the same direction: the service found July 2026 was the joint-second warmest July globally, tied with July 2024, with sea surface temperature over the extra-polar ocean the highest on record for the month.
In the U.S. specifically, the heat had already broken a nearly century-old benchmark. According to NOAA’s National Centers for Environmental Information, July 2026 was the warmest month on record for the contiguous U.S., surpassing the Dust Bowl-era July of 1936.
Meteorologist Jeff Masters added on the same day that the U.S. had also just logged its second-worst July drought conditions on record, behind only July 1934, with 2026 wildfire acreage burned already topping 6.3 million acres — the highest in at least a decade.
Why it keeps happening: El Niño
The driver behind the escalating heat is a developing El Niño event in the tropical Pacific. Yale Climate Connections reported that climate scientist Zeke Hausfather expects 2026 to come very close to being the hottest year on record, with 2027 likely to surpass it once a record-strong El Niño fully takes hold.
Carbon Brief’s independent analysis, based on five research groups’ datasets, currently projects 2026 as likely to be the second-warmest year on record, with roughly a 19% chance of overtaking 2024 for first place — a probability that could rise if the El Niño intensifies further.
The real test comes in early September, when NOAA, NASA, and Copernicus publish their official August assessments. If daily tracking data holds up, August 2026 could join July as another entry in a summer already defined by back-to-back records — continuing a streak that has made nearly every month since mid-2023 rank among the warmest ever measured for that time of year.
