History

The U.S. Signal Service, a predecessor to the Weather Bureau, occupied the summit and kept records from 1870 to 1892. Starting in 1932, the current observatory began keeping records. On April 12, 1934, the observatory staff recorded a wind gust of 231 mph that at the time was the highest recorded wind speed in the world, a record that was held until 1996. The observatory's weather data have accumulated into a valuable climate record since. Temperature and humidity readings have been collected using a
sling psychrometer, a simple device containing two mercury thermometers. Where most unstaffed weather stations have undergone technology upgrades, consistent use of the sling psychrometer has helped provide scientific precision to the Mount Washington climate record.
The observatory makes prominent use of the slogan "Home of the World's Worst Weather", a claim that originated with a 1940 article by Charles Brooks (the man generally given the majority of credit for creating the Mount Washington Observatory), titled "The Worst Weather In the World" (even though the article concluded that Mt. Washington most likely did ''not'' have the world's worst weather). The

Education

The Observatory holds a strong tradition of education. In addition to its meteorological and research endeavors, the Observatory is involved in many educational efforts which seek to inform individuals about the many significant aspects of weather, area history, and the mountain environment. MWObs educational facilities and programs include:
Observatory Toursallow summit visitors to tour the Observatory's summit weather station and research facility. Tours are only offered to MWObs members.
The Mount Washington Museum begun in the 1940s, is located in the Sherman Adams Summit Building in Mount Washington, and illustrates the rich natural history and the fascinating human history of Mount Washington through exhibits, photographs, and video presentations.
Distance Learningallows students grades 4-12 to video conference with observers at the summit and learn about climate and weather from those who experience and study it first hand.
Winter EduTripsaffords the general public the opportunity to overnight on the summit of Mount Washington mid-Winter without a technical mountaineering ascent. EduTrippers typically arrive and leave on a
snowcat, though a hiking descent can be opted into on a nice day. EduTrips have themes such as "Implications of Global Climate Change," "White Mountain Geology," and "Photography on the Summit."
Summer Day TripsOutreach Programsbrings Observatory staffers to schools throughout the Northeastern US. Outreach events typically include experiments, demonstrations, and lessons which aim to help both students and teachers understand weather concepts. Made possible through a grant from
Subaru of America.
