FI Charts ( T120+ onwards) Summer 2025 **READ MOD NOTE IN FIRST

models this evening still on for a temporary blip or breakdown on Monday followed by more settled and warm weather from Wednesday with eastern areas never really getting below 20C daytime values. If these charts verify we could be in for a 2 week spell of warm to very warm weather. The warmth could continue into the 3th week of July and that's about as far as we can go.

The GFS ensembles shows Mondays cooler blip very nicely and most of the runs support a very swift return to warm weather.

Currently it looks like the second wave of warm weather from next Wednesday may not be as 'hot' as what we will get over the next 3 days but there is scope within the model output for mid to high 20s to make a return as early as next weekend.

The rainfall spikes from 16th July are mostly in the form or showers or thunderstorms so no guarantee of things turning more unsettled. July 2025 is most likely to finish up warmer than average. This combined with a slightly warmer than average June means summer 2025 is most likely to finish up warmer than average. August is all to play for and we usually fear the worst for that month based upon our experiences of most Augusts over the past 20 or so years, so will be interesting to see how Summer 2025 finishes up.

19/20C is fairly average for mid summer. 21C is nice summer weather but 25C+ is the gold standard that I look for every summer and some years do not get it once.

It was about 1.5C above average I thought? That's not a huge amount. the first 12 days or so of June were below average but second half of the month it was much warmer and brought the anomaly above average but certainly not well above average e.g +3C.

Just looking at my local station of Dunsany it finished 1.3C above average for June, certainly not a major temperature anomaly. Flicking through other stations it seems most places finished between 1C and 1.3C above average. If June 2025 was the 4th warmest on record it goes to show our June's are normally fairly cool on average.

I think next week is looking less good than it was a few days ago, certainly for western areas it looks like normal service, plenty of rain and temperatures back into the teens before maybe a return to low 20s for next weekend. Still a bit of uncertainty with next week but overall look unsettled and nowhere as hot as this weekend. Heat next week looks confined to London and the south-east of England where the scorching hot and dry summer of 2025 goes on there.

Just looking at all the models and most of them are in agreement of a significantly cooler and more unsettled week next week, temperatures 13 to 20C generally and deep areas of low pressure close to Ireland at times bringing wind, rain and showers. A slight chance of an improvement towards next weekend where it may turn slightly warmer and dryer but we shall see. I definitely think we will have another brief blast of warmth like the current spell but it probably won't be next week, maybe end of July or beginning of August.
