Wednesday saw the temperature reach 33.2°C (92°F) at 5.30pm, the highest temperature recorded in Penallt in the 9 years since records began. It beat the previous highest of last year by a massive 1.5°C.


The temperature was above 30°C between midday and 7pm and dropped quickly in the early evening with the arrival of thundery weather with some rain (3.4 mm).

It wasn't to last however as the following day saw temperatures 12C lower and dropping even more on the Friday, Saturday and Sunday. Curiously, the lowest temperature on the night 11/12 August comfortably exceeded the highest on Friday and Saturday!
