Severe weather is the defining safety concern at Roosevelt Campobello International Park, with thunderstorm wind events leading all recorded incidents at 127 in the dataset — more than any other single hazard. Winter conditions compound the picture significantly, with 90 winter storms, 86 winter weather events, and 51 heavy snow incidents on record, making this coastal Maine park one of the more weather-volatile destinations in the region.
If you're visiting during shoulder seasons or summer, pack rain gear rated for sustained wind and keep a battery-powered weather radio in your kit, since cell coverage on the island can be unreliable when fast-moving coastal storms roll in. Check NOAA's marine forecast — not just the standard land forecast — before each day outdoors, as wind speeds on Passamaquoddy Bay escalate faster than inland areas. For winter travel, carry tire chains or all-weather traction aids, because the single causeway access point can ice over and strand campers quickly.

About Roosevelt Campobello International Park
For many years, Franklin D. Roosevelt summered on Campobello Island. As an adult, he shared with his family the same active pursuits he enjoyed on the island as child. Although he visited less frequently after contracting polio, Campobello remained important to FDR. Today Roosevelt Campobello International Park serves as a memorial to FDR and a symbol of cooperation between the U.S. and Canada.
