Summer has well and truly arrived in Hawke's Bay and temperatures will continue to climb.

Napier is forecast to hit 27 degrees today, which MetService meteorologist Hannah Moes said is 4 degrees above average for this time of the year.

The rest of the week will be mainly fine in Napier with light winds and temperatures ranging between 23 and 27 degrees.

Wairoa residents will be feeling the burn tomorrow when it is set to hit 29 degrees.

Temperatures in Hastings will fluctuate between 23 and 28 degrees, with a wee bit of cloud and light winds.

"The settled run is going to continue throughout this week for Hawke's Bay and a ridge of high pressure which has been over the country for the last couple of weeks is sticking around the North Island this week," Ms Moes said.

She said it will stay mainly dry this week.

"On Thursday it looks as though there's a small chance there could be some morning cloud and showers, but other than that it's a mostly fine-looking week," Moes said.

While this is good news for those wanting to get outside and enjoy the sunshine, the lack of rain doesn't bode well for Napier's water supply.

Napier water reservoirs are at a "critically low level" and residents are being asked to conserve water.

Residents have been warned their water may run out tonight and a total watering ban has been put in place.
