Everywhere south of Auckland can expect some early beach days in November.

Much of the country will see an early start to summery weather in the coming weeks.

Niwa tweeted on Monday that a "very impressive" high-pressure dome, fuelled by La Niña, is likely to hang over the South Island and central-lower North Island for the rest of November.

A very impressive, LaNiña-driven, dome of high pressure is forecast to persist over the South Island & central-lower North Island for much of the rest of November.

It's predicting near-record heat levels in the south and potentially some early beach days for everywhere south of Auckland.

Niwa meteorologist Chris Brandolino told NZME that, over the next week, the South Island could expect temperatures 10-15degC above average.

"This time next week, that's when I think the conversation really starts to heat up."

Temperatures could reach near or above 30degC in some parts of the country.

While that's good news for beachgoers, farmers might be less pleased about summer's early arrival.

Mr Brandolino says the combination of high temperatures and the lack of rainfall could have a severe impact on the agricultural sector.
