Porz Carn in France is a consistent surf spot with the best conditions typically found during the winter months, particularly from November to February. During this period, the swell is predominantly ground swell, with percentages ranging from 70% to 88%, ensuring powerful and well-formed waves. The mean swell size is also most favorable in these months, averaging between 2.2m and 2.7m. However, wind conditions are less ideal, with bad winds (onshore or cross-shore) occurring 80% to 85% of the time, which can create choppy or messy surf unless you catch a clean window. From March to October, the swell quality gradually declines, with increasing wind swell influence and smaller wave sizes, particularly noticeable from May to September when ground swell drops below 50%. Summer months (June to August) have the worst combination of high wind swell dominance (69% to 79%) and frequent bad wind conditions (80% to 84%), resulting in weaker, less organized waves. The shoulder months of October and March offer a middle ground, with decent ground swell presence (58% to 79%) and slightly improved wind conditions compared to winter, though still inconsistent. For surfers prioritizing wave power and consistency, the winter season is best despite the challenging winds, while those willing to trade size for slightly cleaner conditions may find October or March worth considering. Avoid summer if possible, as conditions are generally poor for quality surfing.
