On average around the country she said the temperatures were about a degree or so warmer than average for this time of year.
The sunny skies that have been around for the past couple of days were expected to slip away towards the end of the week, with rain and heavy falls expected to the west and south of the South Island during the second half of Friday.
The rain will reach the North Island on Saturday, with some heavy falls expected in the west.
Some sunshine is expected around parts of the country on Anzac Day, though MetService predicted the wet weather would likely stick around Northland, Gisborne and Hawkes Bay and the south and west of the South Island early on Monday.
Ms Murray said the warmer temperatures would gradually cool down over the incoming weeks.
"We are into autumn now, temperatures are slowly decreasing, we will see them cooling as is seasonal."
