Big temperature range

[Weathermad]

I heard yesterday that Timaru started off the day on 6 degrees but climbed to 34 degrees by early afternoon. That sure is a vast range!

[Pelorus Pete]

In Blenheim yesterday the Cheery-Land orchard recorded 35.7.
It reminded me of Bangkok here yesterday. A nice breeze keeping it bearable

[tunster]

TTx at Blenheim airport yesterday was 34.3C.
At 04Z it was 33C, with dewpoint -9C (corresponding to a very dry RH of 7%), winds gusting to 37 knots.

Hit 32degs here - off to Waimak Gorge for a paddle now that it has clouded over... looks like temp should start to drop in next hour or so... phewiee

[NZ Thunderstorm Soc]

Temperature did drop once the strong southerlies came over here from 31C down to 20C. This in clear, sunny sky conditions.
Yes, I see it clouding over to the west with boring flat uninteresting stratus.
Might see some drizzle tonight

Drizzlechasing....

29 degrees here at 9.30 this morning now its 12.

[Richard]

wow 12 that's a cool down from 29,the southerly got here about 3.00 with only a cooler wind, no cloud.Looking at the clouds at about 2000m they are still racing to the east so this southery change is very shallow and weak.
Pre southerly temp here was 30C,now 19C

[NZ Thunderstorm Soc]

It dropped right down here, this afternoon down to 13C. I had to put a coat on and revert to long trousers whilst mowing the lawns on my ride-on.
I see that Rebecca said on TV One's weather that the high was 33C? Did someone have the heater on ?
I thought it was that warm this morning, but not that warm, especially compared to yesterday's heat?

Oh yeah it was smoking hot this morning around 10am, easily cracked 30

[MoorfNZ]

We hit 31.5degs at midday-ish... then plummeted to 16deg by around 4pm.

[melja]

Came home from twizel yesterday around 4pm and driving down burkes pass the temp dropped from 31C at the top to drizzle and 11C at the bottom.
Had 34C in the camp at benmore on both the friday and saturday.

32.8C was TTx at Christchurch Airport yesterday before the southerly.

[Dean.]

Home from Twizel today,huge temp range yesterday.We had 32 at Ruataniwha until a weak southerly pushed through the Mackenzie about 4pm.The southerly change went through coastal Canterbury earlier that morning with temps around 14 degrees.
Today was the opposite,left Twizel in pouring northwest rain and a chilly 10 degrees arrived in Ashburton to a warm 28 northwester and a muggy (for Canty) 15 degree dewpoint.

[Richard]

From 3C this morning to a high of 31C, a 28 degree difference,not the greatest range of temp ive noticed here but.....

[Twizel Dave]

Hello chaps. When I rang my wife in Twizel she said the thermometre in town was displaying more than 40 degrees.

[NZ Thunderstorm Soc]

Yeah, it musta been crook as temperatures don't get that hot in New Zealand, well this summer, unless you are in a glasshouse or something like that

If ya want to see another real crook temperature gauge,Rangiora has one in the main street that on a daily would be 3-4 degrees out,less on cloudy days though.

[Twizel Dave]

Most summers see temperatures like that in Twizel! The temperature in Twizel is always under reported by the weather people on the telly. We are usually always hotter than every where else but it never gets to the weather people. And we are probably the coldest town as well. My thermometer measured minus 27 degrees a few years ago. Twizel has very much brass monkey weather in winter and it is like a furnace in the summer.

Hmm... the lowest ever 'official' temp for any town in NZ is -21.6C, recorded at Ophir on July 3, 1995.

P.S. Pukaki Aero (2-3km NNE of Twizel) recorded a T-max of 29.1C yesterday. Its highest temp so far this summer was 32.3C, recorded on Feb 6.

[Lukemyster]

Twizel dave get a new Davis station and show us please

Im not too sure how accurate mikes Rangiora weather station is but on the 1st of Jan it recorded

Maximum temperature =37.2 °C on day 01 at time 15:09
Minimum temperature = 6.1 °C on day 01 at time 06:22

31.1C

I agree twizel would definitly be one of the coldest places in winter and hottest in summer i was there in 2008 and it was -10 overnight and stayed below zero all day. It would be interesting to see how cold other towns in the inland south island get that are not recorded.

[NZstorm]

Twizel is a stand out for its winter temperatures but not for summer temperatures although there is a big diurnal range there in summer, about 15C. Mean max 23C, Mean Min 8C in Jan/Feb.

[Myself]

These Twizel claims are "fantastical". Nev posted above an example of the difference between a trustworthy site (Pukaki Aero) and the Twizel pseudotemperature. Also one of the MS forecasters on here posted another example sometime back in January on a day when the difference was very large.
There is no way the terrain in that area is significant enough to account for such a difference, no matter what the locals may claim.
The only reasonable conclusion is that the unofficial Twizel temperatures are ruined by poor exposure (i.e. too much sun or too close to nearby buildings). Or possibly at an incorrect height, or above asphalt instead of grass?
