Conditions at Praia dos Molhes in October
October: Spring Transition with Onshore Trades
October marks a sharp downgrade in surf quality at Praia dos Molhes. Average swell height is still decent at 5.6ft (1.7m), but average period drops to 8.6s and ideal wind frequency plummets to 21%. The South Atlantic High begins to flex, and NE winds reach their annual peak at 23.4%, with ENE (14.1%) and NNE (12.0%) adding more cross-onshore pressure. Swell energy is dominated by ENE (22.2%) and E (20.5%), which is largely short-period windswell rather than true groundswell. Offshore flow from WSW-WNW-NW becomes rare, only about 5.6% of the time. This is a frustrating month: there is wave height, but most of it is windblown and racy. Water temp is 18.8°C and air temps are warming to 17.8°C. Look for early cleanskin mornings or late evening windows when the trades back off.
