Your 2017 Calendar of Weather Holidays, Seasons, and Safety Days

Plan ahead with these seasonal and peak severe weather dates

Groundhog Day. The Spring Equinox. Earth Day. We observe these "weather holidays" and seasons every year, but they aren't the only ones.

As seen in this list, a myriad of other weather-inspired national days, safety, and awareness days are also observed in the United States and across the globe. Be sure to mark them on your 2017 calendars:

Farewell to National Weather Awareness Weeks

As of February 2015, the National Weather Service has phased out its "weather awareness week" events (with the exception of Hurricane Preparedness Week) in favor of seasonal campaigns for spring, summer, and fall. A number of local NWS offices will still participate at the state-level. To learn if yours does, see the NWS weather awareness events calendar (click the underlined text above).
