Re: General June Weather
The only thing I can think of is that most nights a little breeze comes off the Waimak stopping the minimums from getting really low? But why would a breeze be created by a river?

Re: General June Weather
Cold air is heavy and will fall down hill,a good example of this is along the Pegasus bay coast you get lower temps within a few 100 m of the beach than further higher up inland where there is often a very light breeze drifting towards the coast,an extreme example, north Amberley gets a very cold wind falling out of the Waipara valley,this wind can at times can blow as much as 30+kmp.Bradley wrote:The only thing I can think of is that most nights a little breeze comes off the Waimak stopping the minimums from getting really low?

Re: General June Weather
This happens in Reefton. a light breeze is almost always blowing down the Inangahua River, through the narrow gorge. Doesn't get across to this side of town.Bradley wrote: But why would a breeze be created by a river?
Not sure if it's caused by the river, the topography, or a combination.
different scale to the Waimak, but the same situation.

Re: General July Weather
Yes but only there and at a station just east of Oxford where Oxford itself is calm. They must be just the right distance from the mountains for the NW wave to reach the ground... or, the NW is funelling down the Waimak from Staircase.Richard wrote:Its +8 there because the NW has been blowing since 1.00amSkywatcher wrote:... looks like Darfield has a milder micro-climate.

Could do with more stations to see what's happening.

Re: General June Weather
Yes when the NW air stream starts to effect the South Island like it is this morning its the three gorges( Rakaia, Waimakariri and the Rangitata) it get the wind for a start,this wind can funnel out onto the plains a fair way

Re: General June Weather
The calculated mean minima for Darfield EWS for 1981-2010 show slightly higher values for winter months than at Ch'ch Aero (but lower than Ch'ch city), and slightly lower minima in summer, with the annual average about the same.
There's a reading of -11.8C cited in the stats. report for June 2012 for Darfield 2 EWS/Raws, perhaps suspect.

Re: General June Weather
Thanks everyone for their explanations on why the minima here is higher then the airport, in a way it will be good to get some lower minimums when I move to West Melton at the end of the year!!

The wind vane (arrow) on my new anemometer is amazingly sensitive - it's picking up changes at speeds 2km/h even

Re: General June Weather
Same here - my average for June over the last 12 years is 10 days. A mild first half of the month and cold second half resulted in an average temp of 7.1°C which is 0.5°C higher than my "long" term average.melja wrote:Only 6 days into the negatives here so not bad for June.
Of course, the outstanding feature was the rain with 198.4mm recorded over 16 days and the bulk of it between the 16th and 21st.

I thought I would charge people to find out my weather readings. ie. $99 to have a look at my monthly rainfall totals and only 99cents to see what my daily min and max temps are.
Might as well make a buck or two out of one's weather recordings.
... no but seriously, I having problems with my new laptop, it's an ACER. Some of the letters on the keyboards don't work, properly

Re: General June Weather
Max gust of 120km/h at Mangere 9th June according to NIWA. Does not look correct.

Re: General June Weather
NIWA still have this suspicious wind gust for June 9th at Mangere in their June summary. The day was not windy at all but we did have some intense convection cross Auckland early morning and I'm curious as to whether it was a convective wind event (tornado or microburst). There were no damage reports. 120km/h would be the strongest gust recorded at the site since it began recording in 1971. But can we have confidence that the data is correct?NZstorm wrote:Max gust of 120km/h at Mangere 9th June according to NIWA. Does not look correct.

The Mangere site, located at the old waste-water treatment plant, apparently recorded that 120 km/h SSE gust between noon and 1pm, although 10-minute ENE mean-winds were down to about 3 km/h by that time. Even its E'ly gust of 41 km/h in the hour before that looks a little suspicious, although they were up around that speed much earlier in the morn. Heavy downpours ensued around 5am, then just light rain until about 10am. Temps were also consistently around 12C in that hour to 1pm and the sun didn't make its brief appearance until after about 2pm.
