Summer 2025 in the UK may well have had the highest mean temp, but as far as the summer index [SI] was concerned, it was only 8th highest.
Summer 1976 in the UK had a perfect SI of 48, in effect 1976 can only be equalled, never bettered.

As in previous runs, the ECMWF are forecasting that pressure will build in from the NW by Thu, introducing a much colder, wintry spell of weather across Scotland from the 13th-21st.
A milder, zonal type returns after that.

Quite a number of stations with 20 consecutive 'rain days' (>=0.2 mm) at the moment.
We're on 19 (now 20) here in Strathpeffer, and although it's not been overly wet, it's never been completely dry either.
