Ervik, Norway, offers a mix of swell conditions throughout the year, with the best surfing months typically centered around the winter and early spring period. The most consistent ground swell occurs from December to February, with ground swell percentages at 64-72%, mean swell sizes between 2.4-2.5m, and the lowest likelihood of flat days (0-1% no swell). However, wind conditions during these months are challenging, with bad winds (onshore/cross-shore) dominating 79-81% of the time, making clean surf sessions relatively rare. March sees a slight dip in ground swell (60%) but maintains decent size (2.2m), while wind conditions remain difficult (78% bad winds). From April onward, ground swells decline significantly, transitioning to wind swells as the primary source, which are less powerful and organized. Summer months (June-August) have the weakest conditions, with tiny swells (1.1-1.2m), high wind swell influence (76-80%), and poor wind conditions (80-84% bad winds). September marks the start of improving ground swell (32%) and slightly better winds, followed by October, which offers the best balance of the year with 45% ground swell, 23% good wind days (the highest of any month), and a reasonable 1.9m mean swell. November still holds decent size (2.1m) but sees worsening winds again. For surfers prioritizing wave power and consistency, winter months are ideal, though sessions will be wind-affected. If cleaner, more manageable surf is preferred, October stands out as the best month, offering a sweet spot between swell size and favorable wind conditions.
