It was a hot and sticky night across most New Zealand towns and cities last night, thanks to a humid north easterly flow sucking tropical air from south of Fiji. In the South Island temperatures hovered above 20 degrees at midnight in places like Canterbury and Marlborough.
“Christchurch had a warm night with 22 degrees at midnight, 23 at 3am and right now it’s 27 degrees in the city” says South Island weather analyst Richard Green. “Lyttleton is now 23 and it appears that that was the overnight low, while Dunedin Airport spent most of the night in the low 20’s”
Green says a warm gentle Northerly arrived in Christchurch last night around 8pm and pushed the temp back up to 25 by 9.15pm. He expects Christchurch to reach into the lower 30’s today.
Other places to feel the heat last night were parts of the lower North Island, namely Kapiti, Manawatu and Wanganui.
Further up the country and those north of Waikato are hardly noticing a difference between highs and lows. Daytime highs are reaching the lower 20s with overnight lows hovering in the late teens and even remaining in the lower 20s thanks to cloudy, humid conditions.
The humid weather is expected to remain for a few more days with skies clearing on Thursday and a possible shift to westerlies in the weekend could see the muggy stuff clearing away.
