Conditions at Sao Juliao in February
February: Winter's Long-Period Punch
February continues the winter rhythm with average swell height at 2.5m (8.2ft) and a 12.9s period, meaning serious, long-period energy on the majority of days. The swell distribution is again dominated by NW (20.0%) and WNW (18.1%), with NNW (13.0%) adding a more north-northwest angle that still sends rideable waves down the sandbar. Ideal offshore winds (ENE through SE) clock in about 20% of the time - slightly less than January - as the north/northeast airflow becomes a bit more persistent. NNW winds (17.4%) are the big player, and when they blow hard they can put a cross/onshore bump on the faces. Still, the average period remains above 12s, so the underwater structure at Sao Juliao is able to focus even average-sized waves into clean, hollow peaks. Water temperature is 14.2°C, air averages 11.8°C, and rainfall drops slightly to 1.91 mm/day.
