@DerekTheWeather is 26 C the official heatwave temperature then? I thought it was 30 C

I spoke too soon! Usk has reached 26°C this afternoon, so 15 heatwave days have now been recorded in Usk. 🥵

☀️Catching up with a radio legend! Derek and I join Roy Noble on his show to talk heatwaves. 📈 It’s fifty years since the record-breaking summer of 1976. Looking back at that memorable heatwave, and how recent ones compare. 📻 BBC Radio Wales from 5-7pm, Sunday and BBC Sounds.

@DerekTheWeather Hot again in Dolydd Derek 🥵

Congratulations to everyone who took part in the first ever Show Cancer The V charity fun-run for @Velindre in sunny Cardiff today. Great to meet Sam Warburton too. Thanks for your support! 💚✌🏼

A few showers have developed in parts of Powys and S Wales this afternoon due to convergence of winds. Otherwise dry and sunny. Cooler than yesterday. 20°C at Hawarden, Flintshire. 25°C in Cardiff. Dry and cooler tonight with a low of 8°C in Bala.

More dry weather and sunshine on Saturday but some cloud moving south as well. The AROME model highlights the risk of showers tomorrow afternoon mainly in parts of mid, east & southeast Wales. Locally heavy. Any showers will die away in the evening leaving a dry & cooler night.

@daibailey2024 Arome model highlights the risk of a few showers in your neck of the woods early tomorrow evening.

@DerekTheWeather Its a small chance tomorrow evening over the valley der aint it

A few heavy showers developed in SE Wales late this afternoon caused by convergence of winds.

@ChilliFowler June was wetter than average in Cardiff. July very dry so far! A little rain signalled last week of July.

Most challenging year ever re. 3 heatwaves, no rain and trying to grow veg in concrete like soil! @DerekTheWeather Any idea when we are next likely to see rain in S. Wales?

Usk, Monmouthshire was the hot spot in Wales today with a maximum of 30.8°C Nearer 26°C tomorrow and on Sunday. Dropping to a comfortable 8 or 9°C overnight.

@Anthony_Burns A few heavy showers brewed-up late afternoon in SE Wales, caused by convergence of winds.

@DerekTheWeather A welcome drop of rain arrived a short while ago, and still coming down? Unexpected @DerekTheWeather ?

A toasty 30°C in Cardiff this afternoon. 19°C in Aberporth, Ceredigion with a breeze off the sea.

@TweetsinEpping Thanks Terry. The Met Office says the present-day CET is calculated from weather stations located at Stonyhurst (Lancashire), Rothamsted (Hertfordshire), and Pershore (Worcestershire). Not sure how built-up these places are.

@DerekTheWeather The area I mischievously call middle England. Suspect with the population build up now the "town" effects that you get have spread to the new towns. No longer rural climates. Was brought up in the countryside in Bucks then we got gifted the new town of Milton Keynes. Moved away.

The Central England Temperature CET index is the longest-running temperature series in the world dating back to 1659. July 2026 is on track to be the warmest on record with a mean temperature of 20.5°C up to the 15th. Current July record 19.8°C 2006. metoffice.gov.uk/research/clima…
