General January Weather

[Thunder081]

Bugger the Kaikoura webcam from snapithd cuts out at 8:50pm yesterday there must of been a power cut when the front went over. Does anyone know of any other kaikoura webcams that have archives? Also has anyone seen any videos of the wind from Kaikoura?

Some more good info about yesterday's southerly buster in this Paul Gorman story…

I remember flying into Dunedin a few years ago and seeing one of these gust fronts from the air. The sea under the gust from was white. Would have made a good photo if I was organised.

I have seen a couple of southerly front's like that in Wellington. The big one was on the 12th of March 2010 where a 216 km/h gust was recorded at Baring Head.

From about 40 seconds on this video filmed on Wellington's South Coast it looks like there was rotation on the water at the bottom left.

Nice sunset tonight.

[snowstormwatcher]

Yes was a awesome sunset last night best ive seen here in a long time..
Southerly change here now so cant see it getting to warm here today.

Is there Aussie smoke in the sky over Waikato? This mornings sunrise was very orange and dull even though it was clear (well slightly hazy)

yes. smoke there this morning.

The sea temperature in the Raglan area was only 18C today. Even 17.6 for a time in the morning. It was well over 20C before Christmas. The cool zone is fairly small, along the coast, possibly will disappear with the incoming warm weather. Quite significant persistent coastal drizzle out there today, while the 7's, only 40km inland was mostly in sunshine by the looks.

It seems like theres a decent chance of another southerly buster on Friday? Having missed the last one last week I'm watching with interest

Not sure when this happened, but have noticed that the location of a poster no longer directly shows on their post - given many of the posts are cryptic about the location being talked about, this limits the information being communicated

A recent update reverted this code edit. I will see if I can fix this up tonight.

A persistent SW airstream for Auckland this January. It gave us a sunny dry month with the warmest temperatures in the east and north, the coolest area would have been the Manukau Harbour where the Airport is. I expect the averages there to only be a little above normal.

[spwill]

Without looking at the data January here was sunny, dry, breezy and a little warmer than average.


Warmer maximums and sunnier to the northeast of the region due to the SW pattern. On quite a few days looking south from here the weather was cloudy while looking north skies were clear. The same pattern in Spring would bring cloudier than average weather to the region.

An exceptionally hot, dry and sunny January for most areas, with many daily temp records broken.

The missing sunshine day at Kelburn isn't really - I have notified NIWA of the reading for the "missing" day.

Richmond EWS reported 355 hours' sun - more credible than the 356 New Pymouth claimed for January 2015.

Care to shed some more light on that sunshine figure… so to speak?

Metservice report page in the DomPost had the sunshine total for the 23rd as 13.6 hours - which looked right. The CliFlo data has nothing for the 23rd, but I have informed NIWA who are checking. The final January total would then be 257.5 hours (not a lot above average but easily the best since 2015).

^ Thanks Rupert. Have updated the table above.


P.S. Only 12.5mm of rain here since Xmas… at least a 2 week waiting list for water-trucks atm…
