An end in sight for the heat and humidity but will the heatwave break with a bang – Thursday 25th June 2026 – Sunday 28th June 2026

Hi all,

We are currently in a heatwave with 4 days over 25°C (rounded) and above.

Sunday: 24.7°C
Monday: 27.1°C
Tuesday: 29.9°C
Wednesday: 29.4°C

It has felt especially hot due to the high dew points making it feel awfully humid and that humid feel won’t really be gone until Sunday.

In fact on Tuesday I broke my all-time (records since August 2012) Highest Dew Point record.

Previous: 20.7°C on the 1st of August 2013 at 2:51pm.

New Record: 21.8°C on the 23rd of June 2026 at 4:44pm.

Remember UV levels are HIGH, 7-8, which is expected at this time of the year, regardless of temperature.

Very humid on Friday morning with dew points predicted at 21°C – it might challenge the new record

So when will the heatwave end? Originally it looked like Friday but now it will be Sunday when max temperatures return to the early-20s and fresher air arrives. Before then, there is the potential for some strong or severe thunderstorms breaking out. These could start as early as Thursday evening and Friday across the UK and continue to brew into Saturday. As you know, pin-pointing the exact location of these storms is hard and near-impossible as this stage but they could well be significant. It’s not really been mentioned on the TV forecasts yet. So be prepared for some severe weather and look out for the latest forecasts and warnings.

Thursday: A hot and sunny day with some fair-weather cloud bubbling up. Becoming windy into the afternoon with a hair-dryer southeasterly. Very humid. Variations in temperatures across the region. A tropical night and uncomfortable for sleeping with temperatures expected to still be 23-24°C at midnight. Risk of some big thunderstorms later in the night (maybe more so up the western side of the region). Max 28-33°C Min 21°C Max Gusts 25mph

High 30s for part of the UK on Thursday! Small chance of 40°C.
Thundery showers possible during the early hours of Friday

Friday: The heat remains, and the humid feel will again be through the roof. There is a chance of a few thundery showers in the morning but these will move away to allow for some hazy sunny spells to develop. As the afternoon wears on there could be a thunderstorm or two that pop up as clouds develop and the air gets unstable. Lower night temperatures than recently. Max 31-33°C Min 16°C Max Gusts 20mph

Friday’s maximum temperatures will be early-afternoon.
Temperatures dropping slightly Friday PM as cloud amounts increase and a risk of thunderstorms develops

Weekend: Relief will arrive eventually.

Saturday: Potential for some thundery downpours, so look out for updated forecasts/warnings on social media nearer the time. Otherwise another hot day with sunny spells and maximum temperatures will keep some areas in the heatwave threshold. Windy. Max 24-27°C Min 16°C Max Gusts 25mph

Sunday: Finally – some relief as fresher air moves in and we have a day of sunny spells and showers, some heavy, perhaps thundery. Windy again but you will appreciate the wind to cool the house down. Max 21°C Min 12°C Max Gusts 30mph

Sunday’s predicted maximums. Thankfully back to the early-20s.
Roll on Sunday – dew points back to single-figures, hence much fresher air!

Outlook: Temperatures will return to normal next week but pleasant enough for the first few days with sunny spells and a few showers. As we head into July it looks like it will turn more unsettled with spells of rain and temperatures dropping to below average for a time.

It looks like an unsettled start to July
Cooler than average to end June and head into July

Warm and muggy with some rain and sunshine – possible heatwave but still some uncertainty on how far NW the heat gets – Thursday 18th June 2026 – Sunday 21st June 2026

Hi all,

The poor month of June continues but temperatures have cranked up a notch compared to recent weeks and with that so has the humidity, so it’s feeling rather muggy at times. This theme will continue over the coming days, with most of the rain to our northwest and heat to our southeast.

As you will have read, there is a heatwave coming to parts of Spain and France, where temperatures could exceed 40°C. Some of this heat will affect parts of England, mostly the southern and southeastern parts where temperatures could reach the mid-30s for a day or two. Luckily, if you’re like me and hate the heat, we’re not expecting to see any of those values up here in the northwest but we could see a couple of days close or in the mid-20s.

We’ve had a lot of rain during June, but it looks like the second half of June will not be as wet.

Only 3 days without rainfall in June 2026 so far

As always, don’t forget that UV levels are high at this time of year or even very high. So don’t forget to slap on that sun-cream if you’re out in the sun for any length of time.

Thursday: A very warm and humid day to come with plenty of sunny spells (cloudy the further west you are) and a wind picking up into the afternoon. Low chance of a shower later. A warm night follows. Max 25°C Min 16°C Max Gusts 20mph

Some intense heat coming to western Europe – with 40°C+ possible in France

Friday: Another very warm day, bright spells and increasingly windy. A cold-front will be moving through the region later in the day so it will cloud over towards evening with some rain or showers. Max 24°C Min 13°C Max Gusts 25mph

Weekend: Decent and becoming warmer again.

Saturday: Because a cold-front has gone through, it will be fresher with a westerly wind but it’ll still feel very warm in the sunny spells. Again the chance of a shower, especially early on, otherwise dry. Max 21°C Min 11°C Max Gusts 20mph

Sunday: Looks like a cracking day for Father’s Day. Light winds, very warm once again and plenty of hot sunshine. A humid one for sleeping. Max 24-26°C Min 15°C

Outlook: At this stage it looks like temperatures will remain close to the mid-20s for Monday and Tuesday, so if we do have 3 days of 25°C or more, then it will be classed as a heatwave. There will be a risk of some thunderstorms on Monday but after that high pressure should strengthen, and midweek onwards with the wind turning back to a westerly direction temperatures should return back to the early-20s but conditions should be settled with lots of dry weather and warm sunny spells.

Most likely temperatures for us by the middle of next week. Potential for hotter (see below) but low risk.
Some model runs suggest that we could be very hot by the end of next week, but at the moment it is favouring temperatures to be in the early-20s rather than the early-30s. One to watch though. Image from a clip from @WxNB_ on X.
The favourable outcome is for cooler conditions to eventually come in from the west towards month-end.

Becoming warmer but a heatwave looks unlikely – Thursday 11th June 2026 – Sunday 14th June 2026

Hi all,

It’s been a dismal June so far with only an average temperature of 13.4°C and 1 day where rainfall wasn’t measured. 38mm of rain fell in the first 9 days of June and there’s more to come before we slip into, perhaps only briefly, a much warmer, drier and sunny spell of weather.

June 2026 so far…..

Thursday: A miserable morning with heavy rain which will be slow to clear during the afternoon. A little drier towards evening and a muggy one. Windy later too. Max 17°C Min 12°C Max Gusts 25mph

Widespread rain on Thursday
Muggy and humid air Thursday evening

Friday: Showers for the morning and windy once more. Drier and warmer for the afternoon. Max 20°C Min 11°C Max Gusts 30mph

Weekend: Improving.

Saturday: Cloudy for the morning with a few showers possible. Winds easing later, sunny spells developing. Max 18°C Min 11°C Max Gusts 30mph

Sunday: Sunny spells develop more widely, dry and very warm, possibly warmer than the current forecast suggests. Max 22°C Min 12°C Max Gusts 20mph

Outlook: Very warm for a time then turning more unsettled from the west as cooler air arrives.

Thanks for stopping by to read and just a quick blog this week as it’s another busy day for me.

Thanks,
