October: Spring Transition and Trade-Wind Return
The storm track is starting to pull away. Average period drops to 8.7s and the S/SSW/SW share of the swell spectrum falls to about 11%. Meanwhile E/ENE/ESE trade energy once again becomes the dominant wave source, keeping the average height at a deceptively solid 1.8m (6ft). For a south-facing spot like Cardoso, these directions aren't ideal: waves tend to be shorter period, less focused, and more susceptible to onshore texture. The ideal-wind percentage drops to 22%, meaning the lineup is more often rippled or bumpy. Water has started to warm to 19.7°C and air sits at 20.0°C with 4.12mm/day of rain. October is a transition month - expect occasional S pulses, but don't plan around them.
