While the first morning of summer may be a little wet, people in the Bay of Plenty can expect fine weather by the end of the week.

The MetService says temperatures are on the rise.

Meteorologist Andy Best says a convection current moving over the country could result in some light showers tomorrow morning.

'The Bay of Plenty can expect a few light showers in the early morning during this first day of summer,” he says. 'These are expected to clear, becoming fine.

'Winds will be light and temperature-wise, locals can expect a high of around 21°c degrees.

'We've had a lot of convection, that's the bubbly cumulous clouds, which has started to form over the country for most of the week.

'These produce quite heavy showers for inland areas and some of them have drifted to coastal areas too,” says Andy.

'Associated with this has been thunder and hail for some areas around the country.”
