The reign of cold, Autumn-like, daytime highs will remain over the South Island’s southern and eastern coastline centres for a few days, that’s according to WeatherWatch.co.nz’s head weather analyst Philip Duncan.
Mr Duncan says temperatures during the day will remain in the teens for most places south of Christchurch near the coast. “Cooler air brought up during the weekend isn’t moving away and no warm air is set to move in for a few more days yet. Temperatures aren’t likely to climb above 20 with centres further south, such as Dunedin, only hovering around the mid-teens”.
He says temperatures further inland should be higher, including the West Coast and northern coastlines. “They didn’t get the cold air during the weekend and certainly places inland can still heat up nicely in the hot summer sun, most likely all into the lower 20s”.
WeatherWatch.co.nz says UV levels remain extreme despite the lower temperatures and reminds people to avoid the sun during the middle of the day and afternoon.
In the North Island light rain moved into Auckland and a number of western areas but conditions should improve over the next couple of days.
However another sub-tropical low is on the way for Friday and Saturday and this low may develop into quite a rainmaker. At this stage WeatherWatch.co.nz predicts heavy rain to affect the West Coast, Nelson region, Kapiti, Manawatu, Taranaki and King Country.
“The humidity will also be on the rise again and coupled with the summer heat it may be a muggy end to the week and start of the weekend with overnight lows in northern centres around the 21 degrees mark again”.
But Mr Duncan doesn’t expect the heat to be as stifling as it was last week. “This low is going to be further south and therefore not pulling air from as far into the tropics as the last low did”.
WeatherWatch.co.nz will continue to monitor the progress of this sub-tropical low with more updates as the week goes on.
