June this year was an especially dry month, just 42.3mm of rain reported - making it the fourth driest June according to MetService records dating back to 1991, while only 27.3mm was recoded at the same station in June last year.
That was a drop in the bucket compared to the 156mm of rain that fell last month in Palmerston North - twice the average amount for August (66mm), and a record wettest for August at that station.
A MetService spokesperson said the dominance of westerly winds has been the main factor for the August rain.
Westerly winds are forecast to stick around until the middle of September in the region, after which more settled conditions are forecast to return.
