Conditions at The Alley in October
October: Short-Period Chaos
October is when The Alley's surface quality takes a real hit. The average swell height ticks back up to 1.0m (3.3ft), but period falls to 7.4s and ideal winds sink to 29 percent. The swell is plentiful, with E (22.7%), ESE (19.2%), ENE (16.5%), NE (10.2%), and SE (13.7%), but it is short-period windswell rather than clean groundswell. NNW winds lead the rose at 21.9%, with NNE (8.3%) and SSE (10.5%) adding inconsistent texture. Air temps average 21.2°C, water temps have warmed to 21.5°C, and precipitation climbs to 2.50 mm/day. October surfers have to hunt for synoptic wind shifts; a strong cold front behind a low can still line things up for a few quality hours, but the default mode is bumpy.
