Standing in the Clouds: Mount Washington's Extreme Weather

Standing on top of Mount Washington in New Hampshire feels like stepping into a giant outdoor freezer. Rising 6,288 feet into the sky, it is the tallest peak in the northeastern United States. Visitors can reach the summit by driving up a winding auto road, riding a historic gear-driven train, or hiking up steep trails. However, no matter how people arrive, they must prepare for some of the most intense weather conditions on the planet.

Why is the weather on Mount Washington so unusually wild? The mountain sits right at the meeting point of three major storm tracks in North America. As strong winds blow across the land, surrounding mountains act like a giant funnel. This squeezing effect speeds up the wind right as it reaches Mount Washington's peak. In 1934, researchers recorded a wind gust of 231 miles per hour at the summit! For decades, that stood as the fastest wind speed ever measured by humans on Earth. Even during the summer months, freezing temperatures, dense fog, and ice storms can appear with very little warning.

To study these extreme conditions, scientists live and work high up on the peak at the Mount Washington Observatory. Founded in 1932, this weather station operates 24 hours a day, 365 days a year. Every single hour, brave weather observers step outside into freezing winds to collect data. They measure temperature, rain, snowfall, and wind speed. Because the summit experiences hurricane-force winds so often, the observatory building is constructed with heavy concrete walls and anchored directly into the mountain's solid granite rock.

Visitors who travel to the top can tour the observatory's museum and see how meteorologists study severe weather. Seeing the heavy cold-weather gear that observers wear and watching high-tech instruments spin in the wind helps people respect the power of nature. Mount Washington offers a rare opportunity to learn about Earth's changing atmosphere while standing right inside the clouds.
