Cooler temps, calmer conditions expected for week ahead

After a period of severe weather across parts of the region, a shift towards cooler and calmer conditions is anticipated. MetService forecasts a reduced risk of disruptive weather as the final week of January unfolds.

Cooler Temperatures and Settling Conditions

The beginning of the week will be characterized by cool and showery weather. However, high pressure is expected to build from midweek, bringing more stable conditions, particularly to the North Island. This transition follows last week’s impactful weather events, as documented in recent reports.

Regional Forecasts

For those observing Auckland Anniversary Day, showers are expected to ease throughout Monday afternoon and clear by Tuesday afternoon. Bay of Plenty and Gisborne are likely to experience mostly fine weather. However, Napier and Hastings could see thunderstorms as a weather trough moves along the East Coast.

The Horowhenua to Wellington region is forecast to have scattered showers and cloudy periods, clearing by Tuesday. Most of the South Island can anticipate scattered showers on Monday, with the potential for heavier, thundery showers in higher elevations.

Did You Know? A trough moving up the East Coast could bring thunderstorms to Napier and Hastings.

Meteorologist Michael Pawley indicated that the unsettled weather is expected to diminish as the week progresses. He noted that showers could become heavy and thundery in inland areas of both islands on Tuesday afternoon due to daytime heating, but most locations should see clearing conditions in the afternoon and evening.

Temperature Variations

Temperatures across the North Island will remain cooler early in the week before rising back to the mid-20s as southwesterly winds subside. Canterbury, however, is expected to experience significant temperature fluctuations. Ashburton and Timaru are forecast to reach a maximum of only 16°C on Tuesday.

A shift is expected later in the week, with strengthening northwesterly winds potentially pushing temperatures in Ashburton and Christchurch up to 27°C on Wednesday. A cold front is also forecast to bring rain to the West Coast.

Expert Insight: The forecast indicates a dynamic weather pattern, with a clear transition from unsettled conditions to a period of relative stability. The temperature swings in the South Island highlight the influence of changing wind patterns and the approach of a cold front.
