The average monthly rainfall in Oamaru was slightly lower than the monthly average for September.

Oamaru received 13 per cent less rainfall than expected last month.

Usually, the town receives 25.8mm or rain in September, but last month there was slightly less, with 24.8mm of rain falling.

Between September 12 and 21, the amount of rain to hit the town was higher than usual, but after September 21, there was no rain recorded for the rest of the month.

David Stewart, of Stewart Hydrological, said the extended run of dry weather was pleasing.

“Average September river flows were below their long-term averages for this month. River flows began the month below average. They rose to above average in the middle of the month following the rain from September but fell again to below average after that. No high or low flows occurred during the month.”

Mr Stewart said farmers were becoming slightly concerned.

“Farmers report the region is getting dry. There have been some warm days and at times it has been frosty. Rain is needed soon to ease the dryness,” he said.

Meanwhile, other parts of North Otago were also drier than average, with Oamaru Airport recording 26 per cent less rain than usual, while Waikoura, Islay Downs and Palmerston were also on the dry side, being 9, 22 and 42 per cent drier than average.
