1960 to 1979 had 6 years where UK temperatures went over 30C in June

1980 to 1999 had 6 years

2000 to 2019 had 13 years

2020 to 2026 has had 6 years so far, and we're only 35% of the way through

The longest period of time from 1960 to 2000 where june temperatures went higher than 30 was two years, reaching 30 in 1975 and 36 in 1976.

2021 was the only June in the last 10 years where temperatures didn't reach that 1975 record.

Why do you choose 1975/30C as your cutoff point for "record heat" when it should be 1976/36C? Clearly 30C isn't unheard of, even in the past.

So even if it goes above 30 every single remaining year it will still be 9 vs 13 in the previous decade?

[onraglanroad]

These are 20 year periods, not decades. How did you think there were 13 years in the previous decade? It would be 18 vs 13 if every year up to 2039 went over 30C.

[rsynnott]

They’ve rendered that in a rather confusing way. 13 incidents is for _two_ decades, not one.

The time frames they are looking at are 2 decade intervals, not 1 decade
