Byberg in Norway is a spot primarily driven by wind swells, with ground swells playing a secondary role. The best months for surfers are typically from late autumn through early spring, when swell energy is higher and wind conditions, though often unfavorable, occasionally align for cleaner surf. The highest mean swell sizes occur from November to February, peaking in January and December with averages around 1.7m to 2.0m. These months also have the lowest percentage of days with no swell (5-8%), ensuring consistent surf. However, wind conditions are challenging year-round, with good winds only present around 11-16% of the time. Offshore winds are rare, and most sessions will require dealing with onshore or cross-shore winds, particularly in winter when bad wind conditions exceed 85% of days. Spring and summer (April to August) see a drop in swell size (0.9m-1.1m) and a higher chance of no swell (up to 25%), making them less reliable for surfing. September to November offers a balance of decent swell size (1.3m-1.7m) and slightly better consistency than summer, though wind conditions remain poor. For surfers willing to brave the cold and hunt for the right windows, late autumn and winter provide the most powerful and frequent waves, while those seeking smaller, less intense conditions may find brief opportunities in early spring or late summer. Overall, Byberg is a spot for committed surfers who prioritize swell over ideal wind conditions.
