Hottest summer on record

NIWA reports that New Zealand’s 2017-18 summer has been the hottest on record.

2017-18: Kiwi Summer for the Record Books

Standout stats:

  • The hottest summer on record by 0.3°C.
  • Hottest summer on record at 54 weather stations
  • The had seas up to 6°C above average.
  • Alexandra reached 38.7°C on 30 Jan, NZ’s hottest Jan temp in 39 yrs.
  • Cromwell had 56 days over 25°C
  • Above normal amount of ex-tropical cyclones (2).

Our summer was shaping up as a very dry one too, until the ex-tropical cyclones brought in some heavy rains.

Apart from noticeably nice weather in Dunedin there have also been significantly different growing patterns, with things like tomatoes and grapes doing much better than usual.

Note that this is a weather record for three months, but it inevitable raises questions about how the climate could be changing overall. Unseasonably warm weather in the Arctic Circle, which pushed cold air down onto the US and Europe, have also been unusual.

    Its been a great summer, if only they were all like this. I note there have been no adverse issues so thats it for me global warming is what we want perhaps with just a tad more carbon dioxide to really get that plant growth booming.
    We certainly dont want the brutal and worst winter on record the Americans have just suffered. New years eve in NY had people suffering hypothermia, one can only hope they were tree hugging climate campaigners 🙂
    I see Antarctica has freezing accelerating according to our own scientists who clearly got that one wrong..at least they are consistently wrong.

      Made up for last summer which was crap.

      I love it when someone like you demonstrates how divorced for reality they are
      summer was crap
      December was great since than we have had rain rain followed by more rain.
      Have a look in the supermarket fresh veg is expensive because of the wet growing season

      One drill in the Ross ice shelf found the ross ice shelf is not melting the Antarctic is losing ice.

      The usa had a brutal winter .

      Consistently wrong?
      That would be You ….

        Who cares Griff, temperature changes and we adapt and thrive. I would hate to be one of those believers in catastrophic climate change, what a miserable existence waiting for the end of days and bemoaning all the amazing strides humanity has made.
        Whingeing gits the lot of them.

          Hello David if you did not care you would not have lied .
          Get caught telling lies and come back with a distraction.
          How typical for you.
          By the way
          My view is shared by ever major scientific body on the planet
          Your view is shared by a few nutters .

            My view is its quite amusing when the likes of yourself spend endless hours studying reports that tells you that the climate changes and that scientists agree with your genius. Well the sun shone this morning and its raining this afternoon so even I agree that the climate changes, the climate has always changed although lately not to the degree we have been warned about.
            I guess wasting your life worrying about something that isnt really happening would leave you a bit prone to over reacting to a differing opinion to your own. Thankfully the proof is on my side at the moment but you win on the computer models and pretty graphs.

    Average Temp- 18.8 Celsius. New record.
    Previous record- 18.5… in 1935.

    • PDB

       /  March 6, 2018

      So in terms of raw data it isn’t a record then as 1934/35 has been adjusted downwards by NIWA by around 0.7 Celsius overall.

        i’m not sure. I just reported the figures. Are you using a mathematical formula?

      • David

         /  March 6, 2018

        Careful with those pesky facts Corky.
        No one knows the mathematical formula that Sallinger used to adjust the temperature records downward before he was fired and exposed as a key player in those leaked emails, he probably just lopped off a degree or two so “hide the decline” makes records a bit useless.

      Invercargill is mentioned as well – hottest day ever recorded beating the previous record set in….January 1921.

    Deniers eh! What cn ya say!

    • Zedd

       /  March 6, 2018

      tautoko RG.. still C-C deniers, massing; led by Mr T etc.
      I still remember when CO2 was about 300ppm (1970s) I hear it is above 400ppm in 2018 !
      BUT some still say “No Evidence of C-C” (ostriches)

    It may or may not have been the hotest summer here, but globally Jan-Feb were in the middle of the pack for this century:

      One thing you seem to be avoiding/ignoring.. whilst there has been the odd peak, in the past, the general trend is definitley RISING.
      May I suggest its ‘time to remove the blinkers’ & broaden your view Folks

      • PDB

         /  March 6, 2018

        The RISING has been happening since the little ice age largely during times where CO2 was never a factor.

      • Alan Wilkinson

         /  March 6, 2018

        Crap, Zedd. I have always said the planet is warming but that the issue is how much and whether it matters. Don’t try to misrepresent me.

      I always thought you were a bit of a space cadet Alan.
      We don’t live in the troposphere at ten kilometers.
      By the way
      Thats Roy “God wouldn’t allow global warming” Spencer’s series .
      You know the one that has been corrected half a dozen times after other peploe have found problems with his work
      I much prefer RSS
      Same data just a better record at getting their work right with out others having to correct it for them .

      • Alan Wilkinson

         /  March 6, 2018

        The RSS chart shows the same pattern for Jan/Feb. So does HadCRUT at least for Jan – it hasn’t published Feb yet. So just spare us the crap and pull your head in till you have something sensible to say please.

    I can’t say that it’s been a great summer in the Waikato. It’s been humid for months, with very few days when it hasn’t been sticky heat, even at night. 36o+ and humidity are awful. Thank goodness I bought extra fans early. One ends up drenched with sweat doing things that aren’t really strenuous.

    It’s been a good summer for shops selling fans and aircon, I suppose.

    Wasn’t a hot February over in Western Australia.

    Seems this “global warming” has a distinct regional signature.
