RWood wrote: Tue 16/04/2019 15:44 The corrected March-April numbers are quite interesting. March 1968 was the warmest on record, with April a little cooler than average, giving a drop of 4.77C. But in 1956, after a record-breaking January and warm February, March was dry and cool, more than 1C below the 1981-2010 normal. Then April was the warmest on record with some ex-tropical visits and very high rainfalls in the far north, resulting in it being 1.09C warmer than March!
So it looks like this April would only need to be about 0.4C below normal to equal or beat that 1968 March-April difference?

These half-month temp-anomaly maps also show just how considerably warmer the last half of this March was to the first half.

That looks about right. March this year was reported as being equal 2nd warmest with 1999, which would give a 7SS value close to 17.56C - so need somewhere around 12.78C or less for April to beat the 4.77C difference, and that is just a little more than 0.4C below April's mean of 13.23C. At the moment that looks easily achievable, but there's plenty of water yet to flow under the bridge - or air to flow over NZ... :mrgreen:

Drove the desert road today and yesterday. Both days were stunning up there. More snow on the mountains than I expected for April.

Grey overcast day, compared to yesterday's lovely fine clear skies.
Still 1035hPa and 11C.
Anticyclonic Gloom. :(
It's a wonder it hasn't come onto drizzle?

Auckland should easily surpass its normal April sunshine quota today, with still 9 days to go... 8)
Hamilton also not too far behind.

Niwa temperature map for the last 15 days, below average temperatures for quite a few areas.

The night cooling has dragged the mean down here.

Well it was for a start but then there some cloud from off shore and later some cirrussy stuff moved in from the south. Here are some pictures from today.

Sunny here but I can see the low cloud coming over the hills to the south, winds coming from that way too, so I can see that cloud spoiling what is a lovely day. :mad:

Good storm out to sea from Tauranga the last hour or so. East of here, regular lightning visible, probably 100-200km offshore at a guess.

Looking interesting for Monday on the GFS and BOM, a very cold pool of air at 500mb moving over the South Island with GFS going for -31C up to mid-Canterbury late afternoon. Looks to be reasonable moisture. Of course it’s a few days out but I thought worth mentioning.

Considering how wet the month has been, our final sun total may not be all that bad.

Nice day at the service at Rangitata Island today. Light westerly.
22 aeroplanes I counted lined up.
Photos later.
