119.1 hrs for Invercargill so far to end yesterday - if this is correct then possibly depending on the total today - could be either be the sunniest May since 1956 (123 hrs) or 1951 (128hrs).

Seems a little surprising though credible - remind me to send you sometime the details of the two sets of measurements (C/S data and the AWS data that started a few years back). Over that period the AWS has been showing about 75-85 fewer hours per year. NIWA is maintaining parallel sets of obs. for several years at a few sites for analysis purposes.

Report from the Southland Times - warmest May ever at Invercargill since records began.

South warms to winter more than summer
The Southland Times Saturday, 2 June 2007

It might have been the first day of winter yesterday but temperatures in the south were still higher than the first day of summer.

Temperatures in Invercargill were about 1.5degC higher on the first day of winter yesterday than they were on the first official day of summer, on December 1.

45 South weather services manager Andy Fraser said this was uncommon but did not indicate temperatures overall were getting warmer.

While yesterday's official temperature would not be obtained until this morning , Mr Fraser said it was 15degC in the city at 3pm, which could be assumed to be the day's high.

On December 1, the high was 13.5degC.

However, Southlanders should not to get too comfortable with the mild conditions, with a cold front headed to the south next week bringing wintry conditions, Mr Fraser said.

Invercargill's mean temperature in May was 10.3degC, the highest since records began, and the mean daily minimum was 6degC, beating the previous highest of 5.1degC in 1999. May was also one of the five windiest months in the past 12 years.

In Queenstown, Coronet Peak is pushing ahead to open next weekend despite bare tussock slopes after the wettest May on record.

Queenstown weather forecaster David Crowe said yesterday that snow was forecast to 800m today.

"We're not expecting a great amount but every little bit helps," he said. "I have never seen the mountains in May so bare of snow in 45 years of living here."

Mr Crowe said more snow had fallen in December and January than in May. Another cold front was expected to reach Fiordland this afternoon before moving into the Southern Lakes. After showery weather and a "little bit" of snow this weekend, temperatures would drop closer towards weather conducive to snow-making, he said.

Coronet Peak manager Hamish McCrostie said he was hopeful the snowguns would be working this afternoon, and overnight lows of around minus 6degC were expected.

"Things are looking good right through the week and our June 9 opening is still a goal. Good things come to those who wait," he said.

Contrary to other parts of Otago, which faced dry and even drought conditions, Queenstown had recorded the wettest May since 1870, he said.

Further north, the first day of winter was more than 6degC warmer in Christchurch than the first day of last summer.

Metservice weather ambassador Bob McDavitt said Mainlanders might have to get used to topsy-turvy seasons because the aberrant currents that brought chilly water and those rogue icebergs from Antarctica to New Zealand, instead of their usual destination near South Africa, were predicted to become more common.

Q'town must have had some NW/W "main divide overspill" rain events. Even Alexandra has some of its highest monthly totals in this fashion.

Here's a few figures from the North Island's East Coast and Hawke's Bay...


Gisborne had the lowest May rainfall for the past 52 years and the warmest May since 1937, with 6.8mm of rainfall and an average T-max of around 21C (or about 3C above normal).

So far this year Gisborne has had just over a third of the average rainfall that could be expected, or just under 156mm instead of the 5-month average of just over 430mm.

In Hawke's Bay, no rain had been recorded since May 8. Soil moisture was 123mm in deficit, meaning it would take 123mm of rain just to saturate the soil.

Napier airport had the warmest and driest May since records began in 1951, with a mere 4mm of rain (or 7% of normal) and a T-mean 13.3C (or 1.6C above normal),

Wairoa had the warmest and driest May since records began in 1992, with 8mm of rain (or 6% of normal) and a T-mean of 13.6C (or 1.6C above normal).

Mahia had the warmest and driest May since records began in 1991, with 10mm of rain (or 7% of normal) and a T-mean 14.5C (or 2C above normal)

It's not all doom and gloom for the ski season though ...

Weather Change Brings Snow To Canterbury
2:36 pm, 02 Jun 2007

The change in weather could bring some much-needed snow to South Island ski fields.

MetService says a southeast change has already brought snow to the Canterbury high country on Saturday and more is forecast for the evening.

Mt Hutt ski manager David Wilson says the fall may not be enough to open the slopes but it should provide the area with a good base.

He says the covering, combined with the dropping temperature, will allow snow-making machines to get to work on the slopes.

The first cold temperatures of winter follow the warmest May on record, with daytime temperatures still in double-digits in most areas.

Gosh Nev @ EC of NI figures, I did hear about it but didnt realise it was that bad - am surprised at the length of it as I assumed it only started from April. Very similar to what Syd experienced (May - wise).

I see AKL is forecast to have at times showery and windy W - SW weather for the next 7 days - will give you much needed rains for once if it actually occurs smile .

Interesting because looking at the sunshine hours for IVC - all years since 1992 (bar 1993) have exceeded the average - quite significantly in some years. Does the readings that's put out in the NIWA monthly summary & data come from the AWS ? Where does NIWA have it's "other sites" at ?

The hardcopy NIWA summary publishes both totals. References in the online reports would be to the "old" C/S series. It also has a pair of sites at Kaitaia - the AWS records less there as well. And also allegedly at Paraparaumu but there's only one set of numbers being printed for there. IVC's numbers being above so consistently is slightly doubtful but it's still unclear. When more places finally do a conversion we might get a better handle on it. Several places that have switched to AWS are getting higher numbers because the old sites had poor or deteriorating exposures or equipment. The total numbers of AWS sites would be about 15-20. In some cases there was a long gap to the former records (over 20 years for Tekapo), and in several more the AWS records are the first ones at the site.

Off current topic, but on general topic - just found out I will be speaking at a conference in Dunedin end of November this year, and see that 30/11/2006 temps were 6 - 11 eek Haven't experienced those sorts of temps since I lived up in the Pyrenees. Is this the average for that time of year? Sheesh - what's winter like!

Guess knowledge of NZ climates is not advanced in your parts! That must have been a fairly cold day. Here are a few sample average max/min for November (average for the end of the month would be about 1C higher):

Ch'ch city 19.2 8.9
Dunedin (Musselburgh) 16.0 8.6
Dunedin Aero 17.5 6.3

That said, temps. can fluctuate considerably. You're in temperate zones below 45S there, not the wimp's world! laugh

That's looking a little healthier (but not by much)! I did a google for the temps I got, and found wunderground.com which is where I found that figure - I picked 30/11/06 randomly, but it does seem that it was not quite an average day now that I check other days. Yeah, I guess I am a wimp when it comes to cold - but hey, I can be found outside in summer happily mowing at midday in 34 degrees with 80% humidity laugh

It's not unduly cool for the latitude - obviously cooler than equivalent NH places in western Europe (no Gulf Stream) but much warmer (year overall) than the eastern parts of the main NH continents at those latitudes.

I see Christchurch and Dunedin both shared T-mins of -4C this morning (and T-maxs of 11C yesterday).

A slight contrast to Christchurch's first day of June, when intervening fohn NW'ers played havoc with temps and wind-speeds - at 2:40am that morning, Christchurch aero reported one Strong NNW'er pushing the mercury up to 20C (equal to the arvo's T-max).

N'erlys turning SW in Auckland atm after a few showers and sunny fine breaks over the last couple of days. Perhaps a little sunnier here on Waiheke with only about 6.5mm to date and very pleasant 15C afternoon.

Looks like a potentially extreme cold outbreak in NZ longitudes in the later part of this week - both EC and GASP are suggesting thicknesses below 524 and 850 HPa temperatures near or below -6 over most of the South Island (and potentially some of the North). If this came off it would mean snow to sea level or close to it.

Yes, could be an interesting this week in the South Island, with high winds for both Islands, thanks to that Gran'daddy High' in the Great Australian Bight.

Mount Hutt skifield got 25-30cm on Saturday night and 60 snow guns now in operation - the mountain needs another 30cm before opening next weekend, although it looks like Saturday's S'erly blast wont ease until Sunday.

Coronet peak was also expected to open next Saturday but had only received only about 5cm snow during the weekend.
