In the past I have noted that these tend to make cool airflows over NZ noticeably colder than the models predict, and we have a cool south to southwest period coming up next week. It will be interesting to see how the temperatures respond.
Your right there Tony. A bit of snow along the Alps and Mt. Peel even got a bit of a dusting.
This press-release from NIWA yesterday is probably not too much of a surprise after NZ's 2nd warmest December on record and January's warmest ever all-time month. https://www.niwa.co.nz/news/five-more-d ... -on-record
Here's some of the main points…
Until now, the hottest summer in historical record is 1934/35 where the temperature was 1.8°C above the 1981-2010 average. This summer is currently running at 2.3°C, 0.5°C above the previous record.
… Summer standouts so far
108 places across New Zealand recorded their hottest summer on record, 21 their 2nd hottest and eight their 3rd hottest.
In Alexandra on January 30 the temperature reached 38.7 °C. On the same day Clyde got to 37.6, Middlemarch 37.4 and Cheviot 37.3 – together these comprise the hottest temperatures of summer.
Wellington has had 17 days above 25°C this summer – the average is two.
Auckland usually has 29 summer days above 25°C, this year there have been 47 – the highest since records began at Auckland Airport in 1966.
Invercargill recorded three consecutive days over 30°C in January. It’s never done that for two days in a row, let alone three.
Cromwell has topped 25°C for 56 days – normal is 35 days.
Dew point temperature – the meteorological measurement combining humidity and temperature – failed to drop below 19°C in Auckland from February 10-15, making it a rare 115-hour period of very high humidity.
In Wellington a dew point temperature of 22°C at 6pm on February 11, the highest dew point on record for the city.
Mahia, Appleby and Waipara West have had their wettest summers on record.
I wouldn't say hottest but the warmest summer on record.
It's like saying "It's freezing outside" when the wind is rather cold and uncomfortable, not to the actual conditions to imply that it is freezing, ie. snow and ice.

Several days to go yet - I suspect some places will change status in the final reckoning. Kelburn was ahead of 1934-35 by a very small margin as of 22 Feb, but the last 6 days will almost certainly change that.
You can see the West to NW clouds moving overhead to the East to Se but there is little to no wind here, if so from the east. However it was North to NW here this afternoon.
I was up on the Lewis tops on Friday and Saturday, on Saturday afternoon there was a very keen NW blowing that required some bracing with tramping poles to keep walking in a straight line at around 1500m. Stunning scenes though with the sun out all afternoon. Wouldn't have been at all good up there yesterday!
To date this is by far my wettest start to the year in over 10 years of records. It’s got its work cut out though to keep up with last year in the coming months. I’m now well over 200mm for the month of feb.
2004 might have been a wetter start than this year but this station wasn’t recording then.
