What is the weather like in Gros Morne National Park?
Gros Morne sits on the west coast of Newfoundland, where the Gulf of St. Lawrence and the Long Range Mountains create a moody, maritime climate.

Winters are cold and snowy—expect -5 to -10°C and strong winds, particularly along the exposed Tablelands. The wreckhouse wind, a local name for intense gusts off the ocean, can make exposed trails unpredictable.
