Cold, rainy weather lingers
CASINO residents have shivered through one of their coldest December days since 1994.
The temperature at Casino Airport reached a maximum of 17.9 at 1.36pm yesterday, which is just above the 1994 record low of 17.5 degrees.
Experts predict rain and lower than average temperatures will continue across the Northern Rivers this summer.
"For the Northern Rivers we're currently looking at a 70-75% chance of above average rainfall over summer," said Bureau of Meteorology climatologist Acacia Pepler.
La Nina conditions were slowly building in the tropical Pacific and it was predicted the current patterns would persist into the new year.
The Northern Rivers experienced an extremely wet Christmas Day last year, with 33.8mm falling in Casino before 9am and 89mm in Ballina.
The La Nina phenomenon generally brings more rain than average to eastern Australia, but Ms Pepler said this summer will not be as wet as last year.
"We had a very strong La Nina last year - one of the strongest on record and comparable to events in the '70s that farmers will remember - but that ended in about August this year," she said.
"A weak La Nina is developing in the Pacific and causing an enhanced probability of wet conditions, but we don't have all drivers we experienced last year."
The forecast was temperatures in the region to rise to the mid-20s over the weekend, with showers continuing on Saturday and Sunday.
The bureau does not provide 28-day forecasts, but past records indicate weather conditions are generally dry in the Northern Rivers on Christmas Day.
Recordings taken at Casino Airport since 1858 indicate Christmas Day in Casino has been dry 69% of the time, while recordings taken since 1992 indicate 60% of Christmas Days in Ballina have been dry.
