Antarctic blast in Oceania! New Caledonia +8,1°C, Vanuatu +13,0°C, Tonga +13,3°C, Fiji +13,6°C, Niue +13,7°C, in New Zealand 24 inches of snow / 61 cm / 24 hours




Firstly extreme floods on Buller River and 24 inches of snow / 24 hours in the Alps in New Zealand, then very impressive Antarctic pressure high above parts of western Oceania, with very low temperatures in tropical islands!

The pressure low system in early August brought the largest flood flow at Bullet River in New Zealand since 1926, while in the mountains, heavy snowfall covered higher elevated centers.

After rain and snowstorm, frosts up to -6,5°C in lower situated regions appeared already 4. August 2021 – this value was measured in Mt Cook, 656 MASL, while Tara Hills (488 MASL) reported -3,9°C or even the metropolitan region of Dunedin (1 MASL) -3,8°C.

According to /https://twitter.com/extremetemps/, extremely cold Antarctic air contributed to anomalously cold mornings within strong pressure high in New Caledonia, Vanuatu, Tonga, Fiji, and Niue, western Oceania, too.

In New Caledonia, only +8,1°C was measured, while Vanuatu, relatively close to Papua-New Guinea, reported only +13,0°C, Tonga +13,3°C, Fiji +13,6°C, and Niue +13,7°C.

E.g., a record low for Suva, Fiji´s capital is only +13,0°C, a record low for Prot Vila, Vanuatu´s capital +8,1°C, or in Nuku´alofa, Tonga´s capital, only +10,0°C.

Not only South America, South Africa, Australia, and New Zealand, but parts of Oceania are from time to time bothered by powerful cooldowns of Antarctic origin, too.
