Re: General August Weather
Whereas last year, May to July was cold and wet and August was very mild with nor' westers over much of Canty.
I reckon this is the bleakest winter we've had for a few years.

Re: General August Weather
My guess is this is warmer than normal for Rangiora, cloudier conditions in winter generally means a warmer average temperature.melja wrote: rangiora my station its only 8.5C so no spring warming here.
August last year was the warmest on record for NZ.

Re: General August Weather
Yes looking at it its about 1C above normal
Looking at the august sunlight for the last 10 years it looks to range from about 187h to 126h this being the lowest but the average is around 150-160h so with only 33.1h for the MTD this is astonishing low.

Re: General August Weather
a 1/3 of that must have been on your northwest day earlier in the month too so averages quite sparse.

Re: General August Weather
Weather this morning has been pretty miserable, brief showers coming and going. Seeing the yellow specks on the radar, I thought I could get some exercise and if it showered it would be light. But no....the rain poured down at Eastern Beach for at least 5 minutes. I got soaked
Looks like the sun is finally about to come out

For the first 19 days, the provisional totals for a few sites:melja wrote:Yes looking at it its about 1C above normal

Rangiora 33.9
Ch'ch Aero 36.6
Akaroa 51.2
Waipara EWS 51.2
Ashburton Aero EWS 57.
All bad totals, but the EWSs have a recording advantage and are probably overstated relative to the other 2 sites.
You were probably due for a very cloudy August though - the Chc'h records show only one August since 1992 with a really significant deficiency, in 2004, and even that wasn't all that bad at 131 hours. On the other hand, 6 of the 7 Augusts from 1973-1979 were well below average.
Until this one, August hasn't been our "grotty" month here in recent years - every August since 1992 at or above average sun, most also drier than average.
Abnormally low totals of sun with only half of the month or so gone have can occur anywhere in any month - in Jan 1971, Blenheim (with a longterm mean of over 260 hours) had recorded only about 39 up to the 15th. Mediterranean, we ain't.

The low cloud has cleared from areas further inland away from the coast on occasions in the past few weeks hence the slightly higher figures for here and WaiparaRWood wrote:For the first 19 days, the provisional totals for a few sites:melja wrote:Yes looking at it its about 1C above normal

Re: General August Weather
That shower just past us and it contained a fair bit of rotation!
Striations (groves in clouds) were apparent too meaning there was a mesocyclone!
I will upload a movie soon, you can clearly see it rotating you can even the air moving down and around it!
but in the meantime here are some pics of the striations!

Re: General August Weather
Maybe a bit of a landspout trying to get going there Tim.
Midday sounding for Auckland shows relatively steep lapse rates. This type of sounding in late spring/summer would be good for popcorn cb's.

Nice photos there Tim, probably the only highlights from August across the country! Definite rotation there.
