A consolidated reference for Brighton climate: monthly averages, rebuilt from public data on a schedule. Expect 5.1 C at the coldest (Feb) and 17.2 C at the warmest (Jul) — a 12.1 C spread. Expect a wet month and a dry month but no real season: 2.88 mm/day in Nov against 1.44 mm/day in Apr. Taken together that is roughly 763 mm of rain a year for the grid cell. Because each page is rebuilt independently, one unavailable upstream never takes the rest of the site down.

What the Brighton climate table shows
Values are multi-decadal climatological averages for the 50.82838, -0.13947 grid cell, not a single year. Rain is the daily mean, so a value of 2.00 mm/day is about 60 mm across a 30-day month. Averages smooth over extremes, so use them for planning rather than for what to pack for next Tuesday.
Frequently asked questions
Is Brighton climate data a forecast?
No. These are multi-decadal averages for the grid cell, not a prediction for any particular year.
Why do the numbers differ from a weather app?
An app shows one location on one day. These are long-run averages, so they smooth out single hot or cold spells.
