Before you head up, check the live forecast above: conditions on the summit change fast, often within minutes. The best months for a clear, calm visit are June through September, but even then pack a winter parka and sturdy boots—temperatures rarely climb above 10°C and winds can exceed 100 km/h.
What makes Mt Washington’s weather so extreme?
The mountain sits at the collision of three storm tracks, and its 1,917-metre peak punches into the jet stream. The highest wind speed ever recorded on land—372 km/h—was measured here in 1934. On any given day, fog, freezing rain, and snow can appear without warning, even in July. For the latest conditions, check the Canada Scene weather hub and the mount washington 7 day forecast before you depart.
When should Canadian travellers visit?
June to September offers the most reliable weather for hiking the Tuckerman Ravine Trail or driving the Auto Road. Snow can linger into early June, and by mid-October winter returns. March-break crowds head for the ski slopes, but summit temperatures then hover around –15°C with biting wind. For a safer window, aim for late July or August, and always review the mount washington snow cam for real-time visibility.
What should I pack for a day trip to Mt Washington?
Always bring layers: a waterproof shell, fleece, warm hat, gloves, and insulated boots. Even in August, a sudden storm can drop temperatures below freezing. Carry extra food and water—the summit is exposed and rescue can take hours.
Is the weather on Mt Washington dangerous?
Yes, especially above treeline. Hypothermia, lightning, and whiteout conditions are real risks. Check the what is the temperature on top of mount washington today and the mt washington weather tomorrow before setting out, and turn back if fog or wind increase.
Can I drive to the summit?
Yes, the Mt Washington Auto Road is open from mid-May to late October, weather permitting. The 12-kilometre gravel road climbs steeply; you’ll need a vehicle in good condition and a reservation. Check the mount washington weather data and live webcams for road status.
