Becoming windy and very warm once again but not likely to reach the heatwave threshold – Thursday 26th June 2025 – Sunday 29th June 2025

Hi all,

Where is time going? Almost a third of summer done.

So far June has an average temperature of 15.6°C which makes it the joint-second warmest June I’ve recorded with records back to June 2013. June 2023 was the warmest at 17.3°C. This is mostly down to some warm and muggy nights, and we have some more of these to come this week.

Thursday: A band of rain to start which will turn showery towards lunchtime. Generally turning brighter and drier into the afternoon but also fresher and windier. Max 20°C Min 13°C Max Gusts 30mph

Early rain on Thursday

Friday: There will be a new weather-front close by to our northwest on Friday. Parts of the region close to this front could well see some light rain with most places cloudy. Some bright spells in the southeast are possible. Starting to turn quite humid and windy again. Warm night. Max 22°C Min 17°C Max Gusts 25mph

If this rain can be a bit further northwest on Friday we will see more in the way of bright spells

Weekend: The thermometer rises into Sunday.

Saturday: Some early rain should move on quite quickly and then a breezy day with sunny spells and mostly dry conditions. Becoming very warm. Max 24°C Min 16°C Max Gusts 25mph

Sunday: Some stubborn cloud to clear and very warm to hot with sunny spells developing. Not as windy as recently. Max 25°C Min 16°C

Outlook: Monday will be another hot one with plenty of sunny spells. Fresher air will arrive on Tuesday with a few showers blown in on a northwesterly wind. After that becomes a little bit more uncertain, but a ridge of high pressure nudging up from the Azores is currently the favourable outcome. So we do see some hot weather as we enter next week but it will be short-lived and shouldn’t reach the heatwave threshold.

A short-lived burst of heat on Sunday and Monday with maximum temperatures well above average. Fresher air returns into Tuesday.

Heatwave on the way then a thundery breakdown over the weekend – Thursday 19th June 2025 – Sunday 22nd June 2025

Hi all,

Spring was a belter, very dry and with some really warm days, but summer hasn’t got off to the best of starts. That said, we are about to experience our first heatwave of the season.

There is a certain threshold for it to be classed as a heatwave and no matter how long it lasts, there is no such thing as a “mini-heatwave”.

Met Office Heatwave Threshold

So far this year the warmest temperature I’ve recorded, came in April (30th) with a high of 25.9°C. That will certainly get beaten over the next few days. There’s an outside chance that somewhere could see 30°C. As we head into the weekend there will be a bit of a welcome breeze picking up and eventually cooler air and also the risk of a thunderstorm or two.

Hot days and warm nights ahead but how long will the heatwave last?

Thursday: A southerly airflow and plenty of hazy sunshine, making it feel toasty from mid-morning onwards as temperatures rocket. With light winds the heat will build and it will be hot into the afternoon. Overnight, expect a warm one but a bit breezier. Max 29°C Min 17°C

Friday: Another hot day but at least a wind will have picked up, helping those who hate the heat. Plenty of sunny spells and there’s a chance that some cloud could bubble up and set off an isolated shower towards evening but the risk is low. An uncomfortable night for sleeping. Max 28°C Min 18°C

💡 Heatwave safety tip: Keep pets cool and drink plenty of fluids with your BBQ 😉.

Temperatures will be well above average later this week as a short-lived heatwave (longer for the SE of the UK) occurs across the region.

Weekend: Change into Sunday. Thunderstorms possible.

Saturday: Starting to feel more humid and after a morning of sunny spells, cloud is expected to bubble up and there will be a few scattered thundery downpours into the afternoon/evening and also overnight. Again it will be breezy and a switch to a westerly wind later into the night. Max 29°C Min 16°C

Thunderstorms possible before a cool down into Sunday

Sunday: Winds are now expected from a westerly direction, so this will have an impact on the temperature knocking it back down several degrees. Another reasonable day ahead with sunny spells but it will be breezy and there is a slight chance of an afternoon or evening shower which could be thundery. Max 23°C Min 15°C

Outlook: A mixed bag into next week with bright spells and a few showers. Temperatures returning to 19-20°C for a few days and then becoming a little bit warmer towards the end of the week and hopefully high pressure will build again. But at this stage what pans out after midweek next week is uncertain. So stay tuned to my social media accounts for updates.

Humid for a time with some thundery rain or showers before slowly settling down – Thursday 12th June 2025 – Sunday 15th June 2025

Hi all,

My weekly blog is back after a few weeks off and a cracking holiday in Zante and whilst I was away it pretty much rained every day back home and the very dry conditions have eased with more rain in the last 2-3 weeks than there has been in the previous few months.

Today, Wednesday, we have picked up a southeasterly feed which is dragging in much warmer and humid air. You will have noticed that it’s turned out on Wednesday to be a very warm day but the question is how long are these conditions set to last?

It’s going to remain humid for a couple of days, but we aren’t going to be seeing wall-to-wall sunshine. Weather-fronts will be moving in from the west and the southwest during Thursday and Friday so we are expecting some rain which could be thundery at times. It’ll be fresher by the weekend.

Thursday: It’ll be a warm and humid start with some sunny spells, but cloud will soon increase from the southwest. As we head towards the afternoon, a band of thundery rain is expected to arrive lasting a few hours and it will turn windy. Later in the day and heading towards late-evening it should become drier but it’ll still remain muggy leading to a uncomfortable night for sleeping. Max 23°C Min 15°C Max Gusts 30mph

Thundery rain later on Thursday.

Friday: Friday will be another humid day with some sunny spells, but cloud will bubble up later into the afternoon and there will be some isolated thundery showers breaking out which will be hit-and-miss. Once these move through, especially overnight away to the north of the region, slightly fresher air will arrive behind them. Max 24°C Min 12°C Max Gusts 25mph

Weekend: Not too bad at all.

Saturday: Sunny spells after any overnight rain pushes away to the north. I can’t rule out a dry day with a few showers breaking out into the afternoon, again these could be thunderstorms. Otherwise not too bad and feeling fresher. Windy at times. Max 20°C Min 10°C Max Gusts 25mph

Sunday: It looks like a decent day with conditions perfect as the humidity has now moved on. Sunny spells, dry and a little bit windy. Max 19°C Min 10°C Max Gusts 25mph

Outlook: As we head into next week, high pressure will initially ridge up from the Azores but for the first few days we will get some cloud coming round the high pressure from the northwest, but is it expected to stay mostly dry. Later in the week the high pressure will centre itself across the UK and we can expect the week to be dry with plenty of sunny spells and because of the wind direction, temperatures are expected to be around normal with no heatwave or high humidity expected. Beyond this is uncertain so make the most of next week and enjoy some pleasant temperatures.

High pressure centred over the UK next Wednesday.
A mostly dry outlook after this weekend.
