Looking nice up there.
Another day of low cloud cover and light winds. Another 2mm of rain overnight. 17.5c for today.

Have hit 25C before midday. See Jamie's station has also. That would be above average even in mid summer as solar noon is not until 1:07pm

27 odd degrees today. Getting bloody hot for November. Haven’t looked how much above average I’m running but it must be very high.

25.7 here today with mainly clear sunny skies, warmest this month so far. Looking like we'll end the month about 1.8C above average!

Running over 2C above average in parts of NI according to NIWA. No one extreme high temperature but the consistency has been very notable. NIWA will have to extend their chart if this keeps up.

Cloud clearing away overnight to become a fine blue dome day but cloud returning later this afternoon and evening.
Today's maximum was a lovely 23.4C with a light south-easterly. A great day for photosynthesising.

[David]

Up to 26.1C here for the last day of the month making it the highest of the month.

Wow just checked. I’m 2.7 degrees above my normal for November. That may well be the biggest above normal I’ve ever experienced.
Brian is there a way of seeing what the record above normal for any month is in weather display?

Looks as though there has been some thunderstorm activity in inland Marlborough today.

I kinda forgot to post this on here but on the 15th of November at 5:59pm - 6:11pm I was tramping on the start of the Heaphy track near Karamea and saw a waterspout!

I was unable to get all the rain radar images but there was another waterspout near Hokitika and on this radar image it kinda looks like there's a hook echo on one of them

Up to 26.1C here for the last day of the month making it the highest of the month.

See via radar the rain never made it up that far. Got to 22.3 here even with on/off rain and no sun.

Be worth checking Jan 2018, forgot how hot that month was, some stations were nearly 5C above average. See the Herald is saying that the sea temps are starting to match end of November 2017 https://www.nzherald.co.nz/nz/another-n ... B42MXXSIU/

some areas look to be warmer than 2017 already.

A typical Scottish day with it being overcast and drizzly this morning for St. Andrews Day.
However it did clear this afternoon before low cloud moved in from inland areas to over the plains.
20.4C for today, the last day of the Meteorological Spring.

Persistent warmth last 10days of the month for Auckland. I will call it an early start to Summer.

The month ended with a stunning evening in Christchurch, after a lot of miserable claggy rubbish in the rest of the month. Not unexpected, but also not always enjoyed very much!

November 2021 looks set to topple 2019 as NZ's warmest November on record. It was also generally dry, except for the East Cape, north Otago and the north West Coast.

MetService November 2021 Summary - One for the record books

Day to day the weather maps didn’t change much at the start of November, with high pressure centred across much of the country, and a low skirting around its northern flank. This low came to a halt near East Cape driving flooding rain onto eastern North Island prompting a state of emergency declaration. Gisborne Airport recorded its wettest November on record by far with 288mm of rain, 214mm of this falling in just 72 hours to the 5th.

Northwesterly winds then brought a prolonged spell of windy weather for South Island, and the lower North Island, pushing the mercury to near heatwave levels for eastern North Island mid-month. Humidity became the weather word of the week late in the month, especially for North Island, but it was warm almost everywhere. Monthly temperature records tumbled across North Island as Whangārei (18.6C), Auckland (18.2C), Hamilton (17.1C), Tauranga (18.4C), and Taupō (15.3C) all recorded their warmest November’s on record. Westport and Hokitika came close to breaking records but took a silver medal.

The final weekend of the month was a wet one for the West Coast with Westport recording its wettest November day on record with 97.2mm of rain in 24 hours.
