On a wet day for parts of the North Island, we have a big change in our wind flow â€“ plenty of easterly quarter winds after a couple of months of plenty of westerlies.
The easterlies are caused by two things â€“ a low in the North Island and high pressure in the lower South Island.
Rain will fall along eastern areas of the North Island, and even as far south as North Canterbury.
This low hangs around until Wednesday with another Tasman Sea low forming by the end of the week.

Despite the climbing ENSO numbers in the central Pacific we aren’t seeing real El Nino conditions in NZ. The current spate of of ex-Aussie depressions in the north Tasman is not what we call classic El Nino where anti-cyclones would normally reside, and the flat,compressed west-east isobars would flow over central & lower NZ causing drought on the east cost in the long run. This definitely ISN’T happening an I’m definitely NOT complaining!
