Conditions at Barrio in December
December: Maximum Power With an Onshore Price
December offers the biggest, most powerful surf of the year at Barrio. The average swell height hits 5.2ft (1.6m), the period reaches 10.0s, and the NE quadrant is virtually the only source of surf, with NE at 60%, ENE at 25% and NNE at 8%. A large share of observations sit in the 3-6.5ft (1-2m) range, and over 11% push into 6.5-8ft (2-2.5m), giving the beach a serious winter energy level. The trade-off is extreme: ENE and NE winds combine for more than 42% of all wind observations and often blow 20-40kph directly onshore, so the waves can quickly become messy and blown out. Ideal offshore S/SW winds arrive only 7% of the time. When the two align, Barrio is a legitimate heavy, hollow, winter surf spot; most of the time, it is a challenging onshore paddle that rewards the dedicated.
