Mount Washington Observatory has been taking hourly weather observations from our mountaintop station since 1932, and we have digitized much of our dataset. If you are interested in data from 1949 to the present, first check availability, then complete this form. For data prior to 1949, please email for details as that time period is still undergoing quality assurance.

Unless you are a research partner of Mount Washington Observatory there is a cost associated with most data requests. Please submit your request and we will respond to you via email within 2-3 weeks.
