Some of you may have heard of this - But for those who haven't there is some impressive heat building rapidly over Southern Spain and North Africa.

The all time record for April in Spain is 37.4C. There are hints that 40C could be hit which is just incredible for April.
This maybe hit on Friday or Saturday.
Keep tabs on this.

ECM average temps show 38C tomorrow so I'd imagine the max values are a degree or two higher.

It was mentioned on the BBC forecast yesterday evening. Far too hot for me! I'm glad it wasn't that hot when we went to Calpe in March.
At least it will be mild!

Last year, when it got to 39C here, the dewpoint was 10C, which works out as around 19% humidity.

Similarly the hazel lost a lot of its leaves due to the stress.

What we're seeing forecast for Seville is even more severe than that, and it literally turns the environment into a tinderbox.

Thundery rain or showers are forecast for parts of the UK this Sunday. I wonder if this is the legacy of Iberian heatwave; the heat not quite reaching the UK but heading north enough to generate mid level storms.

Morocco also broke its April record yesterday with an extraordinary 41.3c in Marrakesh.

I've stickied this for a good reason. Already a new European record has been set for April with I believe over 38C  recorded in Cordoba (Spain) . This certainly won't be the last record we'll see this summer.
I'd like this thread/topic to be the one to use for European heat records for this summer. At the end of September I'll move it to the classics section so it can be used for anyone undertaking research.
This is an excellent forum for this and as a moderator I like to assist in the likes of this.

It’s advised on days like that not to leave the city and we have a complete fire ban, no welding, no bbqs etc even in the city.

All well and good for Western Europe but I'm off to Bulgaria next week. Last year the same week was 24-26C and sunny every day apparently. Current forecast is for 14-16C and thundery showers every day. just what you want on an outdoor holiday - not!

Record low day max's i think. New snow on the mountains after a snowless winter which wrecked their skiing industry. Then it improved gradually, creeping up each day but with almost continuous grey skies with just the odd glimpse of the sun when temperatures crept up to 20C. Never a breath of wind. In fact the weather was ideal for walking and the bird watching tour and any warmer would have been oppressive. Shame not to see the beautiful Pirin and Rhila Mountains in clear blue skies though and my astro photography intentions were scuppered. Still could have been worse - could have gone to N.E  Italy which is not so far away from SW Bulgaria.

Worth keeping tabs on the continent now. I think this summer is going to shape up as one special.

Some record breaking heat starting to show its hand in Europe now. Corsica had its hottest ever June day today 41.6c.

Could be some more records over the next week or so as a significant heatwave develops over southern and central Europe.
