Conditions at Playa Grande in October
October: Maximum Rain, Maximum Southwest Groundswell
October is the wettest month at Playa Grande, with average precipitation of 9.07mm/day, but it also produces the most westerly-tilted swell of the southern season. SSW remains the dominant direction at 53.8%, while SW jumps to 36.3% and WSW adds 3.8%. This is the month with the highest proportion of true southwest swell, which is nearly ideal for the west-facing coastline. The average period is 12.7s and the average height is 1.4m, so waves have both size and grunt.
The weaker point is the wind: ideal wind sits at only 57%, and the rose shows a broader spread of onshore westerly and variable southerly flow. When the trades do establish a clean E/ENE breeze, Playa Grande can be surprisingly good, with clean 4-6ft (1.2-1.8m) faces and occasional bigger sets. Water temperature remains warm at 28.3°C. This is a late-wet-season wildcard - rough around the edges, but capable of producing the best groundswell of the year.
