Dry conditions are likely to prevail across Canterbury for at least another week.
Cooler temperatures are forecast this morning after Christchurch reached 31 degrees Celsius yesterday but the relief will not last.
MetService predicts only a few millimetres of rain will fall today before mid-afternoon.
Beyond that there's little or no rain in the outlook through into at least the middle of next week.
A large high-pressure system is expected to become slow-moving or stationary east of the South Island from tomorrow, which will keep rain-bearing systems to the north and west at bay.
Spokesman Dan Corbett said the "blocking high" would extend up through the depth of the atmosphere.
It would only slowly begin to collapse once the collective weight of weather systems north of the country and on the other side of the Tasman Sea started to push across into it.
The high was likely to bring cooler daytime temperatures, peaking in the low- to mid-20C range, and easterly breezes.
However, it would commence a spell of dry weather into next week.
