Report Your Frost or (How low did you go)

[tich]

Had some overnight rain which dusted the hilltops around Akaroa (700m+) with snow, then cleared up to give a frost. Just had another light shower.

Clouding up nicely now from the North

At Lake Tekapo this morning it was -7ËšC. We went up there on Friday through Omarama, beautiful hoar frost up there. Near Twizel we stopped at a pond on the edge of the highway to see Australian tourists standing in the middle of the pond. We suggested that the ice wasn't quite deep enough to do it safely and they shouldn't be jumping to much in one place with 5 of them there. They then mentioned that they had heard quite a few cracks

Anyway spent the weekend ice skating at the rink, going to the Mt John Observatory to see the stars and snowboarding at Roundhill. The temperature didnt' get above 0ËšC the whole weekend.

A Bit of a hoar frost in Gore this morning nice and sunny now hopefully seen the last of the fog.

[Andy]

Fog still here temp -3 degrees. Hoar frost up in the fog barrier.

[Gary Roberts]

Awoke this morning to the heaviest Hoar frost I've ever seen. Everything is white. It's like living and working in a deep freezer.

It was -10 °C at 06:08 and lots of fog. Quite spectacular.

Yea hoar frost here too Gary, very thick out Fruitlands and the Ida Vally, Omakau areas some build ups are in excess of 3-4 inchs Temp in Alex -6.6, but would be alot colder in the above areas.

I edited my previous post as you were writing yours!

Do you ever get up to Lauder? I hung out with the beardie weirdies at NIWA's site there a couple of years back (Many of them are amateur astronomers and a big part of the Central Otago Astronomical Society and Alex observatory.)

And a new 2007 low for Twizel this morning of -8.6 °C at 07:50ish.

So a lot of the hoar frosts in Alex and surrounding areas are really Rime, especially with the constant freezing fogs?

...and if these frosts occur in nurseries, would they be called Nursery Rimes

Very probably. I always call them Hoar frosts because I'm ignorant and lazy.

Ya know, people have been knifed for telling better jokes than that. I'm just saying.

I like that Joke john, clever

It's -7.7 °C in Twizel, after a morning low so far of -8 °C at 08:11. The usual foggy conditions and rime ice everywhere.

Omarama is at -9.5 °C now and fine again as usual.

A woman who normally works out of Christchurch posted on the Meridian intranet news site that Twizel had a "Hore" frost and was down to -10 °C. When I emailed her to explain that Meridian's own weather station gave a low reading of -8.8 °C she didn't deign to reply...or correct the misinformation on the Meridian intranet news site.

Human beings are the absolute worst judges when it comes to weather conditions.

I feel a bit left out with all these hoar frosts around, we've had a couple of nights which have been lightly foggy but around 3-4 c, then last night just as it dropped below zero and I was hopeful of a hoar frost as it was a bit misty too,a breeze picked up and the cloud came in.

[Gary McConnochie]

A hoar frost in Rolleston would be a very rare occurrence indeed. I have seen it get pretty close at times but never to the point where things start turning white.

...and if they occurred in brothels, they'd be called whore frosts.

Seriously, I wonder how coastal is this cloudy and drizzly stuff in Canterbury - in other words how far inland would you have to go to escape it.

Still -4 here

Interesting to see those persistent very cold day time temps down there.

I see the temp at Auckland Airport fell from 16C (NE) to 14C(SW) mid afternoon, first seabreeze ?, up to 17-18C over the Ak isthmus.
