Police warned driving conditions in the south of the island were difficult
Overnight snowfall combined with below freezing temperatures has put Guernsey's runway out of action.
Airport director Colin Le Ray said: "Conditions are still fairly treacherous."
Police are also warning that driving conditions are difficult in the south of the island.
Traffic Sergeant Martyn Harris said ice was causing problems on the roads for a second day running and they were closely monitoring the situation.
Alderney's airport is also shut.
Delays are likely with the closures of destination airports in the UK and the other islands.
Bus services are also disrupted with some services not operating and some are running a reduced service.
