What’s in store for King’s Birthday weekend?

MetService meteorologist Mathapelo Makabulane told the Herald Kiwis should expect a “noticeable cooler feeling” in the air as winter begins this weekend.

She said that would be due to a southwesterly flow over the country.

Makabulane said overall, the long weekend was not looking like a washout at this stage, but there would be periods of showers.

She said coastal areas in the western parts of the country, as well as the lower South Island, could have breezy southwesterlies which might create some large waves.

“That’s maybe a bit of an early heads-up for anybody who is thinking about being near the coast in those areas.”
