General July Weather

[Awhituobs]

132mm for me (140 is around normal for me)
temperature just above normal (20 years of averages)..that is what Niwa will have too for Auckland I suspect
edit: despite the frosty start

I see tuesday now looks like a good gale SWer for upper NI

The less stormy weather trend continues here.
The feature of July weather for Auckland this year was the run of cold mornings to start the month, much of the region getting 5 days in a row with frost.

Despite a cool start, July 2021 ended up warmer than normal overall. Very heavy rain around the west and north of the South Island mid-month caused severe flooding, especially around Buller, while eastern areas remained relatively dry. Sunshine was mostly above normal.

Not here judging from the 21 frosts in July and the state of my woodshed

July 2021 was the 6th-equal warmest July on record. Six out the seven warmest Julys on record have occurred since the year 2000. The mean temperature for July 2021 was 8.9°C which is 1.1°C warmer than average (1981-2010).

With last June being NZ's warmest on record, and this July its 6th-equal warmest on record, August wouldn't need to be that much above normal to beat last year's warmest winter on record...
