    Hehe. it was actually mostly sunny most of the time, except on-the-hour when they made the observations ... and with the UV index at the 11 (extreme) level today at 1pm, it was probably not a good idea to be out in it!

    Now at 6pm it's still a fierce 33C with 41C humidex ... and due to get even hotter the next two days. I would expect we have an overnight "low" of around 26 or 27C tonight!

    Average over the past 24 hours was 29.1C ... it didn't go below 26C last night ... and is currently (at 4pm) 34C ... the great heat continues!

    Makes me laugh, though, how the media panics and expects huge electricity consumption "due to all the fans and A/C" .... but forgets that 75% of people here in Quebec heat by electricity in winter. At +34C outside, it's only a delta of 13C to the internal temperture, which is only 1/3 of the delta of 35-40C in the depths of winter. But, then, media types are not the smartest knives in the drawer are they :(

    It's getting worse - mean temperature now for the past 3 days is 29.4C ... and it's currently reading +36C in the shade in my garden! The cooling-degree-day values over the past three days (up to 11.5) are the highest I've seen since emigrating here in 1993! If one accounts for the latent heat due to the humidity, the cooling load is equivalent to a heating load with an outside temperature of about 2.5C

    I was at Landsend today and it did not rain and as far as I could see no one got blown over, so very clement here too. Outside temperature just as the Archers finished was 18.5 C :devil:

    Yeah, coolish today, but we shd tell Paul we've been having our own extraordinary heat wave too. My cabrio roof's not been up for 6wks, and we spent 10 days sleeping under the stars, rarely even dewy at dawn.

    It is hard to find a decent roofer these days isn't it.:bigsmile:

    Posted By: fostertomut we shd tell Paul we've been having our own extraordinary heat wave too.
    I heard about that - sounded better than last year's "summer of disappointment". This is the first real heatwave we've had for 3 years - sure we hit 30C the odd few times in the past couple of years, but not day-in-day-out like this week. The last time we hit 18.5C in the daytime was on the 10th June - it's been in the high 20s low 30s ever since. My cabrio also has been roofless for a while - I must admit that yesterday I was driving top-down with the A/C on (just blowing on my feet). As cold air is dense there is surprisingly little mixing at around-town speeds and I was comfortably cool. I know, waste of fuel etc. But I was out cycling around town today, despite the heat.

    I just took a photo of my frying an egg on our basement sloped door - and one of the thermometer on the deck - as well as the one on the definitely off BBQ

    Paul,

    Just out or curiosity - do you prefer to live there where there are definate seasons, where summers are hot and winters are wintery? or do you miss the " its either cold rain or warm rain " of our seasons?
  12.  
    I love the fact that there are well defined seasons (though Spring always seems short as we can go from winter to full summer in sometimes only a couple of weeks). The cold of the winter leads to an anticipation of spring and the fruits and vegetables follow the seasons too: fiddle head greens in early spring, then asparagus, strawberries in June (though this year we had them in May), now raspberries and cherries. As a child in the UK I always wished for "proper" winters ... can only remember about three or so. Over here, well, they are long, but have got shorter by about 4-6 weeks since I emigrated here in 1993. No doubt the climate is changing here.

    A nice long hot summer always feels like a payback for a cold snowy winter (though it was neither snowy nor cold this year, relatively speaking).

    Paul in Montreal.

    Fried Egg, you can take the boy out the North but never take the North out the boy! Mind you nearly everywhere is North for me.

    In 1976 we fried an egg on the tin roof at work for a lark.
    Just about to go watch the waves at the harbour, shall be taking a jumper.

    Paul,

    Amost poetic!

    I would like to live somewhere, where ( with reasonable confidence ) I would know what the weather was going to be like and not bank on hope.

    Yuo know - plan to go to the beach, plan to spend the weekend in the garden in the vegatable patch, plan to go sledging folowed by hot supper - and not have to cancel and disppoint everyone because of the flippin weather ( again ).

    Southern Europe is nice but I would miss green panaramas.

    Oh well - I'll stick with living underground then !

    I remember seeing people do this on TV in that glorious summer of 1976 ... (I clearly remember 26th June 1976the temperature hitting 92F in Hull - it was the day I had my 1st digital watch) ... which is what prompted me to try it today - especially as the BBQ thermometer was reading above the protein coagulation temperature for egg white ... my main challenge was that the sun moved and the only hot metal spot was the sloping doors of the basement entry - not exactly ideal, but it gave the idea. And you're right, I'm still a Yorkshireman at heart!

    Did the watch have a brown plastic case with red numbers that only lit up when you pressed a button, TI made them I seem to remember, I had one.

    You could never move to Southern France, they like the eggs runny, tres bien!

    Posted By: SteamyTeathey like the eggs runny, tres bien!
    I quite like my eggs runny too ...

    My watch wasn't the famous Sinclair kit that was available at the time (called The Black Watch) but was one made by Fairchild (I think it was called Timeband or something like that). Chrome case and red face, press a button to light up the display. I clearly remember the date saying 26:6 on that hot Saturday afternoon in Hull!

    Now the egg is ready:

    Couldn't agree more. Haven't had one in years - an even then it was an act of desperation as I was in the middle of nowhere having to fill up my car and it was all there was :( I burped the rest of the way to my destination :( Ironically, it was hot that day as it is today!

    <blockquote><cite>Posted By: SteamyTea</cite>I was at Landsend today</blockquote>When you've got time to yourself, leave the Emmets and try Carn les Boel, the next headland south, and Nanjizal cove.

    Well the heatwave is over for now. It got to 31C this morning before the first of three storms which have dumped 68mm of rain so far today! That's a heck of a lot of water in what was only 45 minutes of actual rain-time. So ends the great heatwave of July2010 - the hottest spell since the 1940s ... though summer has only just begun and it will be back in the 30s next week.

    Paul in now cooler Montreal.
