Cadiz - surf spot statistics

Cadiz, Spain, offers surfable conditions year-round, but the best months for consistent, quality waves are from November through March. During this period, ground swell dominates (38-66%), providing more powerful and organized waves, with mean swell sizes ranging from 0.9m to 1.1m. December and January stand out as peak months, combining higher ground swell percentages (56-66%) and slightly better wind conditions (18-20% good winds), though onshore winds remain frequent (80-84% bad conditions). February and March still deliver decent swell (1.0-1.1m) but see an increase in wind swell and less favorable winds. From April onward, conditions decline significantly, with ground swell dropping sharply (as low as 5% in July) and wind swell or flat spells becoming prevalent. Summer months (June-August) are the least reliable, featuring small, wind-driven waves (0.5-0.7m) and consistently poor wind conditions (over 90% bad winds). Autumn (October-November) marks a gradual return of ground swell, though wave quality remains inconsistent until winter. For surfers prioritizing size and clean conditions, the winter window is ideal despite challenging winds, while summer is best suited for beginners or very relaxed sessions.

July in Cádiz offers generally small but rideable surf with an average swell height of 0.6m and a decent period of 6.7s, providing some energy despite the modest size. The majority of waves come from the W (23.76% at 0-0.5m, 36.08% at 0.5-1m), with smaller contributions from WNW and WSW, meaning the swell direction aligns reasonably well with the beach orientation. Wave quality is limited by size, as 85.3% of waves are below 1m, and only 1.9% reach 1-1.5m—mostly from ESE, SE, or WSW. Wind conditions are rarely ideal (just 7% of the time), with the most rideable winds likely being light offshore NNE to ENE (less than 20kph). However, prevailing winds are often onshore (W to SW at 10-30kph), which can create choppy conditions. Experienced surfers may find occasional clean, knee-to-waist-high waves early in the day, but expect generally soft, small surf with wind interference. Bring a longboard or high-volume fish for these conditions.
