After a wet start, Whanganui's weather was settled in June but MetService is expecting a stormier July.
This follows a warm May which changed when winter hit suddenly with colder temperatures and a lot of rain in Whanganui in the first week of June.
Whanganui Airport got 27mm on June 1 and 29mm on June 5 - more than half of the month's total of 96.8mm, MetService meteorologist Stephen Glassey said.
Stormy weather swept across the upper North Island, and there was enough snow to open Ruapehu's Happy Valley learner ski area.
On June 1 a plane flying from Palmerston North to Christchurch was turned back shortly after takeoff, after being struck by lightning.
