For reference this grapevine has been growing in this spot since 2003. There has been no change to structure around it or overhead canopy. It has never been protected. It has never shown any damage to spring growth until this event.

Re: Polar Blast - Oct 5-6
Yep if they are in any frost pockets certainly, hadnt heard it had gone down that low for Hamilton.
Its not so much the blossom but the tiny developing fruit that get damaged

Re: Polar Blast - Oct 5-6
What has not been affected that I can see are any of the normal deciduous ornamental trees, even small ones with very tender looking new leaves out, or any ornamental blossoms Can't tell anything has happened if only look at them.

Re: Polar Blast - Oct 5-6
I imagine there could've easily been several record low daytime maximums on Thursday in North Island.

The best memory is not as good as faded ink but I don't remember -3C in October in the last 20 years. I recorded a min -1.1 on my station solely due to heat radiating off buildings I think.

Ruakura's -2.0C this morning was also its 2nd lowest Oct temp from records since 1907. Only -2.2C in 1933 was colder.
Here's a few more Auckland temps this morning from NIWA:
0.8C .. Pukekohe
1.8C .. Motat
2.4C .. Albany
2.5C .. Mangere

Re: Polar Blast - Oct 5-6
Yes, max temps were well below normal in the North Island on Thursday, but probably not low enough to be record breaking?

Re: Polar Blast - Oct 5-6
Yea certainly some frost damage around here. More than we would typically get in an October or even November frost.

Re: Polar Blast - Oct 5-6
This was the temp inside the bedroom at the bach on Friday morning. Maybe we should think about getting some insulation...

Re: Polar Blast - Oct 5-6
This air came through Macquarie Island before it reached NZ and according to the BOM pages this station broke its October minimum record with a low of -6.0°C on 5th October. The old record was -4.6°C which was set on 26/10/1969. The record extends back to 1948.
