July 2026: Weather Records and Temperatures Against Normal
July 2026 is settled: the figures use data received up to 9 November 2026, more than 45 days after the month ended, so the late station reports are in. This page compares July 2026 at weather stations worldwide with each station's own 1991 to 2020 July normal, ranks it against July of every year since 1951, and lists the weather records, events and storms of the month.

Stations are averaged in 5 degree grid cells and the cells are weighted by the cosine of their latitude. A value and a rank need cells holding at least 50% of the weight of every cell that has ever had data for July; n/a means fewer stations have reported so far. The world includes Antarctica and islands without a continent row.

Of the 6,955 stations with a full month of rain data in July 2026, 33% had less than half their normal July rain and 4% had at least twice their normal; the median station had 73% of its normal. A station month needs 28 days of rain data, because a total from fewer days is too low, and a normal of at least 10 mm.

July 2026 in Context
These values come from other sources and the site's own analysis pages. They are context for July 2026; this page does not say that any of them caused the temperatures or records above.
How These Numbers Are Made
Each station's mean daily maximum and minimum temperature for July 2026 is compared with its own mean for July in 1991 to 2020, from months with at least 20 days of both. A station needs 20 such years for a normal. The mean is the average of the two differences. A station month more than 15 C (27 F) from its normal in either element is treated as a data error and left out.
For the world and each continent, stations are averaged within 5 degree grid cells and the cells are averaged weighted by the cosine of their latitude, so dense networks do not outweigh sparse ones. A continent uses the stations of its own countries. A year gets a value and a rank only when its cells hold at least 50% of the weight of all the cells that have ever had data for July, the rule of the climate pages. This is a station based view: places without stations are not covered, and it is not a gridded temperature analysis.
Records are the site's public ledger: one record per observation, set or tied, at its broadest timescale. The ten year comparison uses daily temperature records only, ties excluded. The numbers and sentences on this page are generated by code from the station data; none of them is typed in by hand.
