Rainfall last month ranged from 42% to 93% of normal at our monitored sites, with a regional average of 62%. And the region had rain on only seven to 13 days during the month.

Kotare (Tongaporutu) recorded just 42% of its normal October rainfall with 102mm. Other sites below 50% were Motunui (49%), Okoki (47%), Charlie’s Clearing in the eastern hillcountry (44%) and Waitotara Valley (47%).

Only five of our sites are still below normal: North Egmont (88%), Hillsborough (93%), Mangati (91%), Egmont Village (95%) and Cape Egmont (99 %). At the other end of the scale, Duffys Farm near Whareroa has 1137.5mm of rain so far this year, or 129% of normal.
