July peak daily maximum
Modelled demonstration series · not observed data
British housing is built to hold warmth in, which is exactly the wrong design for this reading. There is almost no domestic air conditioning, so the indoor temperature simply follows the outdoor one up and then stays there overnight. A single day at this level does more harm here than a fortnight of it would in a place built to expect it.
75 years, modelled
Same reading, two normals
| Normal | Mean | σ | Pct | Return |
|---|---|---|---|---|
| 1951–1980 | 27.9 °C | +4.20σ | 99.999th | 1 in 75,000 years |
| 1991–2020 | 28.7 °C | +2.90σ | 99.81th | 1 in 530 years |
Today would be the highest value in the entire 75-year modelled series. Past the series' standing high of 35.3 °C (2006). Nothing about the reading changes between rows — only the yardstick.

The season here
British summer peaks are short and plume-driven — hot air drawn north from Iberia for a day or two, not a season of heat.
Where this series comes from
MODELLED SERIES — not observed. Parameters set from published eastern-England July climatology. The 75 annual values are synthesised. The real-world record cited separately is documented and is NOT part of this modelled series.
Every number on this page comes from a modelled series: 75 annual values synthesised by a seeded generator from published climatological parameters for Coningsby, Lincolnshire. It shows how anomaly reasoning works. It is not a measurement and must not be cited as one.
