Tropical cyclones in 1977

The most active basin in the year was the Western Pacific, which, however, documented only 19 named systems, but had over 50 tropical depressions forming.

Conversely, both the North Atlantic hurricane and North Indian Ocean cyclone seasons experienced very highly below the long-term average number of cyclones reaching tropical storm intensity in recorded history, both numbering 6, respectively.

Activity across the southern hemisphere's three basins—South-West Indian, Australian, and South Pacific—was just almost spread evenly, with each region recording an average total of 12 tropical cyclones.

The costliest tropical cyclone of the year was Hurricane Anita in the Atlantic which struck Northern Mexico in very late August.

During January, a total of 9 tropical cyclones formed within the month with eight of those further intensifying to become official named systems.
