NZ – Australia – South Pacific — A fairly text-book spring pattern continues in the Southern Hemisphere as a Sudden Stratospheric Warming (SSW) event over Antarctica adds a bit more “oomph” to the usual spring westerly chaos

For the most part Spring 2025 is what we’d call a typical “classic spring” with a mixture of lows and highs moving through – but there’s also a definite boost in westerlies across New Zealand and the southern half of Australia.

Despite the blustery spring for some, those in northern Australia continue to lean drier – but more signs of the wet season are now showing up as thunderstorms and tropical showers start to develop.

Eastern New Zealand is also drying out, while the west remains average to maybe wetter than average in some locations.

Despite near La Nina conditions now developing in the tropics, the South Pacific islands, Australia and New Zealand are yet to see any signs of weather changes. We explain all the details in the video.
