Two far north Queensland towns have experienced their coldest May morning on record.
Cooktown, north of Cairns, was 10 degrees Celsius at 6:00am AEST - two degrees below its previous record low.
Coen on Cape York Peninsula recorded just 10.4 degrees.
Forecaster Greg Bond says there is probably frost in some parts of the far north.
"[There was] 3 degrees there at Ravenshoe. That would certainly imply that there would be a frost, or potential frost on the ground there," he said.
"Certainly there would have been some frost around the higher part off the Tablelands there."
