The 1905 Atlantic hurricane season ran through the summer and early fall of 1905. The season was inactive. Of the five tropical storms that formed, only one became a hurricane. That one hurricane achieved major hurricane strength before spinning out to sea.
The first storm of the season, already at tropical storm intensity, was identified on September 6 to the east of Grenada. A small storm, it quickly passed through the southern Lesser Antilles on the morning of September 7. The next day, the storm weakened to a tropical depression before dissipating as a shallow but large depression. A schooner sailing from Bridgetown to Suriname encountered heavy seas just a day out of port and turned back. It was thrown onto the pierhead and wrecked. The captain and a crewman were swept overboard and drowned.
During the reanalysis of the Atlantic hurricane database, a tropical storm was found to have formed on September 11 to the northeast of the Windward Islands. Steadily tracking towards the west-northwest, the storm gradually intensified, reaching its peak intensity with winds estimated at 60 mph (95 km/h) on September 13. After turning towards the northwest, the system slowed and began to weaken. By September 16, the storm weakened to a tropical depression and dissipated shortly after.
A tropical storm formed in the southwest Caribbean Sea and hit Haiti in early October. The storm went out to sea, reaching major hurricane strength east of Bermuda. That island experienced an entire day of gale force winds with gusts reaching hurricane force, but damage was apparently minimal. The steamer Campania was reported to have been struck by a large rogue wave but the extent of the damage was not explicitly mentioned, though the wave was described as "disastrous."
The final storm formed in the Gulf of Mexico and hit Louisiana on October 9. Winds by that time had weakened to just 45 mph and most of those winds were vented over empty marsh. The remnants of this storm did bring heavy rains to the eastern United States and the Canadian Maritimes.
