Month by month
Season: good November to May. Marine life uses the same scale (Best = reliable, Good = likely, Possible = possible, Off = not seen; ? = we don't know yet). Water and rain are 1991–2020 averages.

Rain days: days with 1 mm or more in the ERA5 grid cell (about 30 km across); over tropical seas it counts more light-rain days than a local rain gauge would. Calm days: waves under 1.5 m and wind under 25 km/h. Storm risk: share of years with a named storm within 250 km that month (– means under 5%).

Non-divers: not known whether non-divers can snorkel here
Socorro can only be reached by liveaboard, and the trips are built around advanced diving; Nautilus lists kayaks, paddle boards and skiff shoreline tours, but no source I opened mentions a snorkeling programme.
