1869 natural disasters

The Saxby Gale was a tropical cyclone which struck eastern Canada's Bay of Fundy region on the night of October 4–5, 1869. The storm was named for Lieutenant Stephen Martin Saxby, a naval instructor who, based on his astronomical studies, had predicted extremely high tides in the North Atlantic Ocean on October 1, 1869, which would produce storm surges in the event of a storm.

The 1869 Atlantic hurricane season was the earliest season in the Atlantic hurricane database in which there were at least ten tropical cyclones. Initially there were only three known storms in the year, but additional research uncovered the additional storms. Meteorologist Christopher Landsea estimates up to six storms may remain missing from the official database for each season in this era, due to small tropical cyclone size, sparse ship reports, and relatively unpopulated coastlines. All activity occurred in a three-month period between the middle of August and early October.
