The summer sun made a welcome appearance in many places today but meteorologists are warning people to make the most of it because it will not stick around for long.

Kawerau residents have been sweltering in 28.6C heat, the maximum temperature of the day.

In Hamilton and parts of the East Coast, temperatures have reached 26C.

MetService metrologist Nicole Ranger says the week ahead is likely to be wet, starting with a few showers developing tomorrow.
