October: Spring's Blustery Trade-Lock
October is a reminder that spring in southern Brazil is often windier than winter. Average swell height is still solid at 6.2ft (1.9m), and the swell direction is dominated by ENE (21.4%) and E (16.4%), with ESE (11.7%), SE (11.6%), SSE (10.3%) and S (7.7%) filling in the background. However, the period drops to 8.6s and the ideal wind percentage falls to 14%. NE (26.6%) and ENE (19.8%) winds are firing, and a large chunk of that wind is in the 20-40kph range, which is bad news for wave quality at an ESE-facing beach. The westerly offshore flow is almost absent: WSW (3.8%), W (2.6%) and WNW (1.7%). Air temps warm up to 18.8°C and water temp reaches 18.8°C, with rainfall near 5.1mm/day. There are definite pulses of energy, but most of October is a battle against constant trade-wind chop; you have to pick the fronts carefully.
