COLD SNAP: Chilly nights, 'vigorous' winds, hazardous surf

KEEP your scarves out this week - the chilly temperatures are set to stay.

The Bureau of Meteorology has also issued a hazardous surf warning for the Byron Coast today, with surf and swell conditions are expected to be hazardous for coastal activities such as rock fishing, boating, and swimming.

While not as cold as the weekend, temperatures for parts of the Northern Rivers this week are set to be below average for this time of year.

According to BoM, "a low pressure system over the southeastern Tasman Sea is slowly moving towards New Zealand and weakening while a strong high pressure system southwest of the Bight is moving very slowly east strengthening a ridge to the east".

"The two system are directing vigorous southerly winds along the New South Wales coast."

Winds are expected to gradually ease during today as the low moves further east.


It will be chilly in Lismore at nights where the minimum temperatures are set to sit around 9C and 10C today and tomorrow, dropping to 7C on Saturday - almost 4C below the minimum average for May.
