Conditions at Sealion Cove in October
October: The Aleutian Low Wakes the Cove
October is when Sealion Cove starts to roar again. Average heights jump to 2.5m (8.2ft) with a 10.4s period, driven by the deepening Aleutian Low and the first potent extratropical cyclones of fall. The directional mix is still dominated by WSW (19.9%) and SW (16.7%), with SSW at 8.3%, while W and WNW contribute only about 5%. Periods are good enough for powerful, grunty waves, especially when the track lines up a little more west.
The offshore wind window is at 37%, with ESE, SE and SSE providing the best chances of clean glass. Air temps cool to 5.7°C, water drops to 10.6°C, and rainfall peaks at 9.34mm/day - meaning you'll dodge a lot of storm fronts between sessions. This is the time to start watching the charts seriously; the cove's best season is loading up.
