Killer Point seasonal overview
Killer Point in Morocco is a consistent surf spot with year-round swell activity, but the best conditions are typically found during the winter months when ground swells dominate and wind conditions are more favorable. From October through March, the spot receives a high percentage of ground swells (69% to 93%), which are more powerful and organized compared to wind swells. December and January stand out as the peak months with 88-93% ground swells and mean swell sizes of 1.4-1.5m, providing solid, clean waves. Wind conditions are also best during this period, with good wind days occurring around 48-51% of the time. November and February are also strong months, though slightly less consistent with winds, while March and October offer a good balance of swell and wind with slightly smaller waves (1.3-1.4m). The summer months (May to September) see a significant drop in ground swells (9-46%) in favor of wind swells, which are less ideal. Swell size decreases to 1.0-1.2m, and onshore winds become more prevalent (68-78% bad wind days), making conditions choppier and less predictable. April and September mark transitional periods, with April still offering decent ground swells (64%) but worsening winds (70% bad wind days), while September begins the return of better swell but still struggles with wind quality (68% bad wind days).
