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

Dangerous

A stalled coastal low is bringing dense fog, sustained 40+ mph winds with gusts over 40 mph, and persistent rain/drizzle to the exposed Franconia Ridge, with wind chills in the 30s. The ~1 mile exposed ridge walk between Lafayette and Lincoln would put hikers in near-zero visibility with hurricane-adjacent gusts and significant hypothermia risk. Conditions are expected to improve into Tuesday as the system pulls away, making that a far safer window.

Best window

Wait for Tuesday, September 30th, when the coastal low pulls away and precipitation drops to near 1% with calmer winds; conditions Monday remain dangerous with rain, fog, and strong wind on the ridge

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.
