About Long Range Weather

We show the spread. For every city we put all 51 runs of the ECMWF ensemble on one chart, count how many bring rain, and mark each day high, medium or low confidence from fixed rules. When the models disagree, we say so.

We stop at what can be known. Beyond two weeks we do not invent daily numbers. We show whether whole weeks and months lean warmer, colder, wetter or drier than normal, and how strong that leaning is.

We compare with normal. A forecast of 11°C means little on its own. We compute 1991 to 2020 averages for each place from the ERA5 reanalysis, so you can see whether a day or a week is unusual.

We name our sources. Every block of numbers says where it came from and when it was produced. The full list, with licences and our rules, is on the data sources page.

No ads. The site carries no advertising. Google Analytics runs only if you accept it, and without that the site sets no cookies.

Long Range Weather UK is run by Webso Digital in Wrexham, North Wales. The forecasts are written by our software from the model data, by fixed rules. No one edits the numbers by hand.

We are not a national weather service and we do not issue warnings. For official severe weather warnings, see the Met Office warnings we show unedited.
