Hard to believe we’re entering the halfway mark of 2021 already but here we are in June and the start of winter on the meteorological calendar (Winter also starts June 21 on the astronomical calendar).
La Nina ended back in Autumn and the weather pattern around New Zealand and Australia remains a ‘neutral’ one – which increases the chances of a chaotic pattern with pockets of extremes (as we just saw with the flooding in Canterbury but fairly dry further north).
As we go through June it’s clear the chaotic pattern continues with far more low pressure in the mix – although the few highs that are still around will still impact NZ bringing settled periods, especially northern and eastern areas. This is good news for Canterbury – but not good news for Hawke’s Bay still dealing with drought like conditions.
HOW THE AIR PRESSURE ZONES ARE SHAPING UP THIS JUNE…
LA NINA? EL NINO? No – it’s just neutral for now…

As June 21st is the shortest day, why is June considered the first month of winter rather than a more symmetrical; May, June July?

Hi Nick, this story from 2017 covers what you’re asking about (although it’s focused on the end of winter – but it’s the same topic). Hope it’s helpful: https://www.weatherwatch.co.nz/content/did-you-know-there-are-4-different-end-dates-to-winter

Very hard to make out NZ beneath all those isomers etc. Is there some way to make the outline bolder? A different colour maybe?

Hi Jan, we don’t have much control over those maps, but if you can generally see where NZ is that’s all that matters for these updates as they are not about local regional weather in NZ (we’re just too small for these big picture updates – so it’s more about the general highs and lows and how they will impact our part of the globe. But we will see if we can highlight NZ in any better ways next time.
