We had a partly cloudy night but cloud thickened from sunrise otherwise it may have been a hot day, still very humid.

GFS shows an upper trough crossing the NI Monday, see how the surface conditions look next few model runs for possible heavy shower development Monday afternoon.

My dew point has got up to 25.5 when the sun came out briefly. Even in the cloud we are sitting 24.5-25 dew point. It’s totally mental how warm it is. I liken it to being on a tropical island

Not much night and day difference here with these overcast conditions. 23.6 min 25.7 max

Decent heavy band of rain across Christchurch city now. Heaviest of the day. 14.3c with a 13c DP

Grey dome day with persistent drizzle and the occasional shower. 17.7mm all up for today.
Cool day with high humidity bringing cool moisty conditions with southerlies moderate for a while today but becoming calm this evening.
16.5C the maximum for today but temps were in the low teens for much of the day.

Macquarie Island, which is between you guys and the Antarctic, recorded a record temperature on 8th February which beat the previous record by three degrees.

The BOM page for this station gives the maximum as 17.0°C and also the figure for the next day (9th) of 14.6°C also beat the previous record. I am guessing, as I have not seen the hourly figures, that this might be fohn assisted from the high ground?

Interesting record! It appears that the 17°C record occurred around midnight going by radiosonde data... it also shows quite a strong, warm inversion that possibly mixed down close to the surface? At 205m up on the sonde it actually got as high as 20.8°C with a dewpoint temperature of -7C (RH 15%)! The temperature was also 17.4°C at 923mb or 841m ASL, so rules out a foehn wind. I guess all than anomalous heat that's been around NZ made it there.

Midday 08.02.22: Then midnight which was around when the record fell, note very strong surface inversion: Synoptic map at time of record:

It's below 20°C for the first time in forever, certainly a welcome change

Different kettle of fish down here today. Cold day with 20.7mm of rain overnight and a cold southerly wind keeping today's maximum temperature at just 12.8C. Did a barbie for tea and instead of wearing shorts and a T-shirt and bare feet, drinking a cold beer, had jeans on, warm woolly socks, a coat and hat and a drink of warm milo to keep warm, whilst my wife and our 2 cats were sitting around the fire which we had going for much of the day. Even noticed condensation on my breath as well. Not bad for February.
Might be a frost overnight as the weather is clearing this evening with the moon and stars out. ?

Some stats for the extremely warm start to Feb.

First 12 days mean minimum 21.4C. Also many of the top 10 records for highest daily mean temperature, highest daily min temperature and highest dewpoint were set.

Becoming fine overnight with a cool minimum of 6.2C. Some scattered cloud today but generally a fine day with light but cool winds. 19.1C the maximum for today. Fine evening with a full moon.

Hello Willoughby - thanks for the soundings.

According to the observations (see table below), the maximum occurred around 5am local time. From the soundings it looks like the warm air aloft was mixed down to the ground and the local wind (mostly WSW or SW at the time, although switched more to N as temperature fell back) probably rules out a fohn. It must have felt unusually warm on the island!

A dew point of 12C for Auckland today after last weeks insane humidity.

It's so good! This mask wearing, even when moving heavy equipment is so much harder with the oppressive dewpoints.

Still on the cool side today, even though fine. Snow still visible on the mountains as I came back from Akaroa to Chch late this afternoon.

Misty/Foggy this morning but clearing away this morning to become a fine and warm day. 24C the maximum for today with light NE wind.
Some snow on the top of Mt. Peel from the other day.

Some light rain this morning but otherwise a fine day but with some straggly looking cloud around the 4 Peaks area this afternoon.
0.7mm for today with a maximum temperature of 22.3C.

A generally cloudy day with light NE winds, not fine as the weather forecasts said.
...but another a mild day with today's maximum being 22C.

Looking fairly Thunderstormy on Sunday with a trough passage for the central to mid upper north island. Will have to see how future model runs firm it up.

Fairly active frontal passage over the Tasman at present.

Clear skies pre-dawn with a good view in the north-east of Venus very bright; Mars and Mercury also visible.

Some mares' tails high in the sky this afternoon, also an aircraft contrail forming as I watched.

Up to 30.6°C this afternoon, very pleasant. Now 28.0°C.

Cracker of a sunset tonight amongst the developing showers and convection....

Saw it, was good one. Last night was good too.

Fine warm day with high cloud and light winds. 27.7C for today. Great moonrise to the east this evening. Full moon.

A heavy shower cell passed over my house this morning around 6.30am. woken by the heavy rain. a good soaking for the garden.

Any intel on when we can expect the next decent rainy system up north? Still pretty dry conditions and the outlook is not at all promising from what I can see.
