General July Weather

[Orion]

It's bizarre trying to drive through that 'ground fog'

[David]

Very foggy this morning, cold too with a low of 4.1C

[spwill]

Fog cleared here 8.30am, I see some suburbs still have fog.

[Skywatcher]

Dense fog here since 2am so more flight delays today.

[DTNZ]

Windy day outside today - well, last of day of July took these sun halo pic's earlier on today @ 11:30am.

Takecare,
DT

[spwill]

Cloud cover has arrived here now, currently 15C.

[snowstormwatcher]

Chilly day here after frost this morning followed by Thick high cloud. 6 degrees currently.

[Andy]

Cold day here max temp 4 degrees

[Bradley]

Waddington July stats:
Average max: 13.6C
Average min: 3.9C
Lowest max: 3.6C on 14/7
Lowest min: -4C on 12/7
Hottest day: 21.6C on 5/7

There was also 7 days above 17C. Truly remarkable stats AT LEAST 3C over the long term max. Will be interesting to see what Christchurch airports stats will be for July, will definately be record breaking, but by how much?

[spwill]

Yes, must be some new July temperature records for the South Island, a lack of cold flow but plenty of NW flow, mild air mass/foehn affect.
Temperatures here have been near normal with rainfall well below average.

[Bradley]

Nothing on the way for at least 10 days either mate. Scary stuff.

[David]

For this July the average low here was 6.6C and the average high was 15.2C - near normal figures. Only 46mm of rain though which is very dry

[Richard]

Yes,starts to make you wonder if there will be any nasty cold weather left this winter,to think yesterday was the coolest max temp for three weeks on 14deg while it was 16deg today

[TonyT]

Interesting. Today was our coldest day for a while, didnt make it above 10deg here, once the fog cleared late morning the high cloud was too thick to allow any sun through, and just a light drift off the sea.

Yeah, same here Tony. a light westerly came through around mid-afternoon, but apart from that not much wind at all. The dew remained on the grass for all day and you could see the tracks of people walking across the grass.

Yeah looks like it?
Makes me wonder, with this Climate change thing, whether we will get this years winter in the summer and possibly next years summer will occur next winter?
Just my theory?

Looks like a possible something around 14-16th Aug. A long way away I know but is the first time in about a month that something has at least popped up on the maps. Bet the skifields are real happy with that large dump otherwise they would be in dire staits

[Skywatcher]

I recorded a mean of 8.2°C for July which is 2.4°C above the average of the previous 11 years. July 2005 was the previous warmest with 7.2°C.

Average max 14.1°C (+3.1°C)
Average min 3.2°C (+1.7°C) with 7 air frosts
Max 20.3°C on the 2nd
Min -2.6°C on the 12th.

Rainfall was 45.6mm on 10 days.

[RWood]

Some good totals of sunshine for July. Kelburn (with estimates for 3 days) had its 7th sunniest with 143 hours, though far short of the record 182 hrs in 2000. A very respectable 140 hrs at Mangere, notwithstanding the complaining from a certain quarter ...

194 (Whakatane), 195 (Gisborne), 181 (Blenheim), 194 (Takaka), 180 (Nelson)

[Willoughby]

Is there anyway of finding out the number of hours of fog per year experienced around the country? Im sure Hamilton/waikato would have the most.

I have a suspicion that Taumarunui pips the central Waikato for the number of fog days.

Yes if there was somewhere that would, that would have to be the place.

[RWood]

I recall from old climate commentaries/summaries that of the well-established stations, Taumarunui was cited has having easily the highest average number of days of reported fog. I have a Met.Observations booklet for 1986 (!) which cited 139 days for Taumarunui, 93 for Hamilton Aero (but only 28 for Ruakura!?).

[tgsnoopy]

I have done quite a few trips in to Taumaranui and been surprised to find it foggy after none over the Kaimais and on the way down there. So I too agree it's got to be a high probability of being the foggiest spot in the Waikato/King Country. I've travelled directly through Tokoroa or come down after overnighting in Hamilton via Te Awamutu, same result.

Here's NIWA's preliminary, 'July 2013 National Climate Summary'

'Fourth Warmest July On Record'

The national mean temp for July was 1.2°C above the 1971-2000 July average, with many sites in Canty and Otago recording their highest ever July mean-temps.

The highest national temp was 21.5C recorded at Wairoa, and the lowest was -8.4C at Arthur’s Pass.

Numerous sites also had near-record-breaking low rainfall for July, particularly the upper half of the North Island (except for the Far North), as well as parts of coastal Manawatu, Nelson-Tasman, south Canterbury, and coastal Otago north of Dunedin.

[spwill]

The outlook says

High average temperatures for July were experienced in the South Island and parts of the North Island due to persistent high pressures over the country, causing settled weather.

It was the mild NW flows that caused the warmer temperatures and a lack of cold flows.
