Algonquin Park Official Ice Out Declared April 25, 2022

ImportantWith its higher elevation and thus colder winters, Algonquin Park is one of the last areas to shed its ice cover in south-central Ontario. Algonquin Park's ice out was officially declared April 25, 2022 when a boat safely navigated from the Lake Opeongo Access Point to the Happy Isle Portage in the North Arm of Lake Opeongo. This ice out date is about average in more than 55 years of detailed record keeping. The official ice out date for Algonquin Park has ranged from March 29 (2012) to as late as May 15 (1972). See below for more details.

Cold Water Paddling

Live Views of Algonquin Park

Even though Algonquin Park lakes are ice free, water temperature during spring remains just above freezing for many days after ice out. Submersion in icy cold water can quickly lead to severe hypothermia, a potentially deadly situation. Reduce the risks by:

  • wearing a PFD (personal flotation device) while on the water;
  • staying close to shore;
  • paddling according to your skill/experience level and the weather conditions;
  • packing the proper safety gear; and
  • not taking unnecessary risks.

Learn more about hypothermia and cold water before you paddle.

Conditions on Trails and Portages

Snow is generally gone from most locations other than shaded north facing slopes, dense coniferous forest areas, and an icy ridge packed from winter users of interpretive and backpacking trails. Trails and portages are generally bare, but have snow/ice covered sections, plus muddy and wet conditions, which is typical for the spring season in Algonquin Park.

Satellite Image of  Algonquin Park on April 22, 2022

Image: Satellite image taken on April 22, 2022, showing that ice out is happening in Algonquin Park. Large lakes in the western portion of Algonquin Park remain partially ice covered, while most other lakes are open or nearly open. Lakes showing black are open such as Lake Ontario and Georgian Bay, while lakes showing various shades of gray remain ice covered but the ice is of decreasing quality (see Lake Opeongo). The strongest ice appears bright white (click to enlarge the image).

Spring and Safety

Please remember that The Friends of Algonquin Park advises against ice travel due to a range of environmental variables and the difficulty in detecting hazards. Be safe, stay off the ice. Park visitors are encouraged to stay away from fast moving and icy cold water at this time of year.

Water temperature in spring remains just above freezing for many days after ice out. Submersion in cold water can quickly lead to hypothermia (a potentially deadly situation). Reduce the risks, by wearing a PFD, stay close to shore, paddle according to your skill/experience level, pack the proper safety gear, and don't take unnecessary risks. Learn more about hypothermia and cold water.
