Christchurch has had "above-normal" rainfall last month and that looks set to continue, with more wet weather expected this week.

The National Institute of Water and Atmospheric Research monthly climate summary said Christchurch had 92 millimetres of rainfall last month - 42 per cent above average.

Blue Skies Weather predicts 30mm to 40mm of rain from late tonight to early Thursday. During this time, snow is expected down to 500 metres.

A Blue Skies spokesman said there was "still some uncertainty about just how much rain and snow will fall".

A low-pressure system forming in the Tasman Sea could bring 30 to 40 centimetres of snow above 800m, and 10 to 20cm above 500m, mostly during the afternoon and evening tomorrow. 

"Falls may be a little heavier in Mid and South Canterbury, and a little lighter in North Canterbury," he said.

Another depression is expected to form in the Tasman Sea on Thursday and move towards New Zealand on Friday and Saturday, moving across the North Island on Sunday.

"Another heavy rain and snow event is possible at the weekend," the spokesman said.

Christchurch also had "above-normal" sunshine hours last month.

The average temperature in Christchurch during July was 6 degrees Celsius, but Rangiora scored the highest temperature in New Zealand on July 15 with 22.6C.
