Franconia Notch Weather

For the weather in Franconia Notch today, use the National Weather Service's point forecast for the Notch, the same forecast NH State Parks links from its park page. Then remember that the Notch is a mountain pass: the floor sits around 1,931 feet at Echo Lake and the peaks above it pass 4,080 feet, and NH State Parks warns that in the mountains weather changes suddenly and darkness falls quickly. A sunny forecast in Franconia village doesn't promise the same on Franconia Ridge.

Where to Check the Forecast

• National Weather Service, Franconia Notch: the point forecast NH State Parks links from its park page.
• National Weather Service, Flume Gorge: the point forecast the state links from the Flume page, for the south end of the Notch.
• Mount Washington Observatory: publishes a higher-summits forecast for the White Mountains, useful before a ridge hike.

A tip that applies to any point forecast: look at the hour-by-hour view for the afternoon, not just the daily high. On a long hike, the afternoon is when you'll be furthest from the car.

Why the Notch Weather Is Different

Franconia Notch is a narrow pass between two mountain ranges, the Kinsmans and the Franconias, with I-93 running through the middle. Elevation changes everything here. At the bottom you're at a lake beach. A few miles away and several thousand feet higher you're on an exposed ridge. Temperature, wind and cloud can be very different between the two on the same afternoon.

That's why NH State Parks says the Franconia Ridge Loop is only for hikers prepared for a long day and potentially adverse weather. The state's Hike Safe program says the same in plainer words: weather changes quickly in the mountains, so learn the local weather before you start, and know when to turn back.

What the Weather Means for Each Attraction

• Flume Gorge: the boardwalk is wet in any weather from the brook and the mist, and the state says hours are weather dependent. In 2026 it is open May 8 to October 25, 2026.
• Echo Lake Beach: staffed daily from early June to early September, with limited hours in the fall.
• Artists Bluff and Lonesome Lake: short enough to time around a storm.
• Franconia Ridge: check a higher-summits forecast, start early, and turn back if conditions change.
• The bike path: paved and on the valley floor, a sensible backup when the ridge is in cloud.

Weather by Season

• Late spring (May): the Flume opens and the campground opens late in the month.
• Summer (June to early September): the beach season.
• Fall (late September and October): foliage season, which NH State Parks calls one of the busiest times of the year. NH State Parks adds staff and traffic control over peak foliage season.
• Winter (November to April): most attractions close, but the park is open for recreation. Cannon Mountain runs as a ski area, and the bike path is used for cross-country skiing and snowshoeing.
