FranconiaModerate

Mount Flume

Mild, well-above-freezing temperatures and light winds make for manageable conditions, but recent rain (over an inch in 48 hours) and persistent summit fog mean

What a report reads like

More than a forecast.

Raw weather data is noise. Each morning we read NWS, NOAA, Open-Meteo, OpenWeather, USGS and the observatory for every peak and write down what it means on the trail. This is Mount Lafayette, this morning.

Franconia · 5,260 ft

Mount Lafayette

Moderate

Autumn conditions with dense summit fog, wet rock, and a lingering chance of morning showers. Temps stay well above freezing, but damp air, breezy N winds (20-35 mph forecast at higher elevations, stronger than the light current reading), and near-zero visibility on the exposed Franconia Ridge raise hypothermia and navigation risks. Conditions improve into Wednesday as high pressure builds in and fog begins to break.

Best window

Wednesday morning through midday, when the ridge builds in, fog begins to break, and rain has ended. If hiking Tuesday, wait until late morning after showers taper, and expect no views.

Summit weather, not valley weather

Forecasts by elevation band, from the trailhead to the summit, so you know what changes above treeline.

52 WAV52 peaks

The 52 With A View list features New Hampshire peaks under 4,000 feet that offer outstanding views. Created by the Over The Hill Hikers in 1991 as an alternative to the NH 48. Doublehead Mountain and Welch-Dickey each count as single entries combining their respective summit pairs.

Belknap 1212 peaks

The Belknap 12 features 12 peaks in the Belknap Range near Lake Winnipesaukee in central New Hampshire. Ranging from 1,664 to 2,382 feet, this is a popular training ground for hikers preparing for the NH 48 and a great spring warm-up before the snow melts in the Whites. The official list is maintained by the Belknap County Sportsmen's Association with a patch program for finishers.

Questions, answered.

Each morning we synthesize the National Weather Service, NOAA, Open-Meteo, OpenWeather, USGS and Mount Washington Observatory data for every peak into a single rating (green, yellow, orange or red), the hazards to expect, what to pack, and the best window to go. Instead of checking five sources, you read one report.
