It's not August yet, and already 2026 has tied 1976 for the number of days where the weather station at Heathrow was over 32°C and 30°C, and has beaten the record for the number of days over 28°C (which was set last year).
Today experienced the 24th day of year hitting 30C in London. For perspective in whole of 1980s we had 21 days.
