Your contributions to Mount Washington Observatory demonstrate your belief in the value and importance of our work.
Your donations make an impact. Impact like reporting 8,670 weather observations each year to the National Weather Service for nationwide forecasting models. Creating and presenting 40 free virtual programs watched by nearly 1,000 middle school classrooms, students, and anyone interested in weather, Earth’s climate system, and climate change. 1,460 specialized forecasts produced, reviewed, and published on our website every year to help people make educated decisions when recreating outdoors and especially on the higher summits.

All made possible because of you.
