I expect that there will be some sunshine, with the odd rainy day here and there. Expect some nor’westers at some point. That’s about as specific as anyone will be able to be from three months away, because this is a weather forecasting site and not your local spirit medium.

What are the reasons for the weather maps looking messier than usual now? (I.e. powerful highs, deep lows, shallow lows, unusually-shaped lows, ‘improperly’ shaped highs, etc.). We already know that the reason for the wide variety of weather systems from subtropical lows to deep Southern Ocean storms is that we get this due to the NEUTRAL ENSO phase + slight La Niña indications; is this the only reason or it’s something to do with the ‘normal’ messy winter weather pattern?

Hi there, this is basically quite normal around August/September to see some of our messiest weather systems. High pressure is usually at its most powerful, as too is the polar air to our south – now throw in longer sunshine hours on top of it all and it’s a chaotic mess. Around October to November NZ often gets more into a traditional westerly flow with a bit more uniform pattern to the chaos (although every year is unique).
