A low of 6C is expected overnight on Friday.
“If you’re out into the evening it might cool off a little quicker than you’d expect,” Corrigan said.
Wind will ease on Saturday and there will be clear skies and sunny weather, followed by an overnight low of 5C.
“Those overnight temperatures will continue to be in the lower single digits.”
Corrigan said at this time of year, the intensity of the sun was rapidly changing.
“The good news is the cooler evenings will ease off in the mornings, with daytime temperatures for the weekend sitting at about 18 or 19C.”
Sunday would bring fine weather with little wind, he said.
