Summer weather in New Zealand is proving changeable, but more fine days are still ahead, according to 1News weather expert Daniel Corbett. While the season got off to a slow start in some areas, recent conditions have been pleasant – though residents should be prepared for potential wet spells.
Weak La Nina
This summer has been influenced by a weak La Nina weather pattern in the Pacific Ocean. However, Corbett explains that its impact has been limited, comparing it to a late arrival at a dinner party – picking up what’s left rather than dominating the event. Other factors, such as sea temperature distribution and atmospheric reactions, have played a more significant role in recent weather patterns.
Looking ahead, Corbett anticipates continued periods of fine weather, but notes that weather patterns are becoming more dynamic. This means that while good days are expected, they won’t be consistent throughout the remainder of the season. Residents are advised to have backup plans, just as they did over the Christmas break, and keep raincoats readily available.
An increasing risk of tropical cyclone development is also on the horizon, potentially impacting New Zealand’s weather in the coming weeks. The interaction between continental warmth and these tropical features could lead to significant rainfall events, or “rainmaker days.”
As the cooler seas in the eastern Pacific begin to fade, a more typical summer pattern of high-pressure systems and fronts may emerge. However, the shift towards autumnal weather will become more pronounced after the Equinox in late March.
