SE are the best followed by N then NW then NE then S and then W and of course far at the bottom of the heap are South westerlies,no good for any weather,just gives cold windy showers and sunless clag

We only really get certain directions except rarely and only temporary,
Most our westerlies are actually SW least WSW and often southerlies are SSW and NW are rare apart from frontal passages and NE are common sometimes but ESE arnt and SE hardly blow unless a deep low is moving off the area,Northelies are rare too.

I was talking really in terms of the "gradient" wind and the general level of associated weather, rather than that observed locally at ground level - for most of W'gton there is virtually nothing from a large part of the compass. This graph for Kelburn Met. says plenty about that.

Differences I would expect to find - moderate (not huge) drop in speeds, and a greater proportion of gradient winds in the "dead" zones for us - ie more from both NE-ENE-E and SW-WSW-W. Also in a time sense, shorter duration of windy spells in the bad zones (NW-NNW, S-SSE-SE)Michael wrote:Bet that rose is different now,that was 17 years ago for the latest data,I remember as a kid in Wellington it was windy,and dull with lots of hill drizzel but since then its usually sunny and not that sort of wind,there on random visitsRWood wrote:I was talking really in terms of the "gradient" wind and the general level of associated weather, rather than that observed locally at ground level - for most of W'gton there is virtually nothing from a large part of the compass.

This frosty spell is similar to this time last year, when cold, frosty weather followed a cold southerly outbreak. However, last year anticyclonic conditions persisted over the South Island for a longer period, while pressures dropped in the north. This time, weather systems appear to be more mobile and disturbed southwesterlies look like predominating next week.

drove through a surprisinlgly heavy and squally shower with some small hail and gusty gale force winds.........I thought we had a ridge of high pressure in the area, LOL

The real point is that we still get cold winds etc, BUT the rainfall comes in better-defined falls - ie there are many fewer days of a showery nature than in western coast locales (including Auckland of course), especially in recent decades.Michael wrote:Bet that rose is different now,that was 17 years ago for the latest data,I remember as a kid in Wellington it was windy,and dull with lots of hill drizzel but since then its usually sunny and not that sort of wind,there on random visits

Its called typical SW Auckland weather,no matter how anticyclonic or shallow the flow Auckland cops the lot if a high sits in the tasman,actually its better with a low in the tasman
