Residents of Alberta were golfing rather than skiing this weekend as chinook-like weather brought record high temperatures.
On 09 December, Calgary set a new record of 15.4 C which broke the old record by one full degree from 1890.
The normal daytime high for Calgary is -1 C with an overnight low of -13 C.
Other records were set in Claresholm which hit a summer-like 20.3 C while Sundre reached 16.3 C.
Environment Canada says double digit highs are likely for at least the next few days.
