LOL, not possible here, as our houses and flats are so insulated that it's almost always hotter inside. My flat was hovering at 27-28C from July to late August. And Finland and AC? Only malls are AC's.
Our outside highest lows were 20.9C, 20.1C, 20.0C, 19.8C and 19.7C this summer, and it didn't help to cool down much... I like summer heat, but our insulation is a bit too good during a warm summer.
Look at these lows in the southern tip of Finland in July-August: Synop report summary
17 nights above 20C, 9 in a row.
Pretty impressive considering the latitude... Yea all the homes here are to insulated to and most people don't have AC's (Malls, Cinemas, Ice skating areas, restaurants, and many pubs do - so there are places to cool down if to hot...), though when temps are in the high 20s and 30s we are advised to close all the windows and curtains in the house during the day, and open them at night, keep the fans on, if fans are blowing out hot air then put ice in front of it... That's what they've recommended on the news and I do that anyway if I need a cool down - its all very effective... But 30 degrees is gardening weather!
The only thing I hate about +30C in the UK, is the overreaction from the media... Though much of it is sarcastic and funnyish:
(also embarrassing - that Irish woman at 0.48 really annoys me - we seriously don't need heat health alerts in this country if temps are just in the High 20 low 30s - which is a fairly normal thing in a British summer!)
My dad said that all the news we get on hot weather during a "Heatwave" is ridiculous! A sunny 30 degree day was never a big deal prior to 2003... It was just a nice summers day!
In Argentina the NWS has a system in which all areas work the same way.
In case of heatwaves, it's defined as a period of at least 3 consecutive days in which both daily lows and daily highs are above the 90th percentile out of all the daily records of the 'warm season' (October to March) from 1961-2010.
In case of cold snaps, it's exactly the opposite. At least 3 consecutive days in which both daily lows and daily highs are below the 10th percentile out of all the daily records of the 'cold season' (April to September) from 1961-2010.
For instance, there is a heat wave in Buenos Aires when the Central Observatory (that has a huge UHI) records at least three consecutive days in which both the low is 22.0ºC or above and the high is 32.2ºC or above. On the other hand, there is a cold snap when in at least three consecutive days both the low is 3.8ºC or below and the high is 12.6ºC or below.
Areas of the country where summer averages are below 20ºC don't qualify for heatwaves, whereas areas where winter averages are above 15ºC don't qualify for cold snaps.
For me, the system is a bit flawed for certain cases, as it's not rare that one of the values fail to reach reach the threshold and prevents a very hot/cold period from being considered a heat wave/cold snap, and on the other hand, more moderate events do meet the criteria. However, there is an intermediate concept for the first case, which is 'extended period of high/low temperatures', which would work as a lower degree of warning. It occurs when only the daily high (for hot weather) or daily low (for cold snaps) meet the criteria.
Luckily our state broadcasting company doesn't do those sensationalist reports, but one notorious example of the tabloids was in 2011 when the early June heat was coined as the "sex-heatwave", because some few people started shagging in parks during that.
I've told this sometimes before, but I was at the cathedral park with my ex-gf that June (we weren't shagging), it was 31C, and an English guy came to ask for a light. He asked "is it always like this in summer, this is amazing!", and I said "well, dream on, it will pass soon". Four days later the high was 17C.
The heatwave criterion is three days above 30/24°C (hi/lo) in my department (sorta county). Thresholds vary from a department to another. In the neighboring departments, it's 35/23°C and 35/19°C.
Hello Rozenn
It´s incredible than in most part of France, meteorologist make quite high temperature tresholds (compared to averages of these locations) to defined a Heat wave while in NYC for example (which has similar average of Southern East French cities) a Heat wave is defined by only 32.2 °C !
Or maybe the Heat wave is not defined by the temperature but by the heat index ?

Haha... Kinky!
17 degrees is a massive difference to 31! Luckily this part of the UK rarely sees highs in July and August below 20...
But yer, the news shouldn't report hot weather in the UK unless there something like this:
It should be at least 35C in summer before the news starts annoying people! Sun creme, shutting windows and curtains, and putting on fans is just common sense...
