We don't have any hint of tropical storm generation in the East Pacific yet, but a couple days of higher surf is forecast to arrive from south of the equator tomorrow and Wednesday. Not as big as the one in early May, but still be careful in the surf.
Predicts wave heights increasing to 5.5 feet by Wed, then decreasing: http://www.tide-forecast.com/locations/Manzanillo-Colima-Mexico/forecasts/latest/six_day
Here's a more technical explanation (AND A LOUDER ONE.) Luckily those 8-10 foot waves will be smaller when they get to the La Manzanilla coastline: http://www.nhc.noaa.gov/text/refresh/MIATWDEP+shtml/:
"LONG PERIOD SOUTHERLY SWELL AT 18-21 SECONDS IS PROPAGATING ACROSS THE DEEP TROPICAL WATERS S OF 03N W OF 84W WITH SIGNIFICANT WAVE HEIGHTS OF 8-11 FT. THE LEADING EDGE OF THIS SW SWELL SET WILL REACH THE SW COAST OF MEXICO INCLUDING CABO CORRIENTES AND THE SOUTHERN TIP OF BAJA ALIFORNIA BY EARLY TUE AFTERNOON AND PROPAGATING INTO THE SOUTHERN GULF OF CALIFORNIA OVERNIGHT TUE INTO EARLY WED. THIS LONG PERIOD SWELL WILL LIKELY LEAD TO HAZARDOUS SURF CONDITIONS ALONG THE MEXICAN AND CENTRAL AMERICAN COASTS ONCE IT ARRIVES."
The Mexican sites say about the same.
