Conditions at Troia in October
October: The North Atlantic Roars Back
October is one of the most exciting months at Troia. The average swell height jumps to 5ft (1.5m) and period strengthens to 11.3s, driven by the climatological uptick in extratropical storm activity across the North Atlantic. Swell directions begin to rotate: NW (34.8%) and WNW (33.3%) still lead, but W swell jumps to 12.5% and WSW/SW combined add another 6.0%. That means the southwest-facing beach starts receiving more direct, properly-aligned groundswell.
Wind is still mixed, but ideal conditions reach 40%. Unlike summer, the flow is no longer stuck in the NNW; NNW drops to 19.9%, while the offshore NE and easterly winds become more common (NE sector around 19%). There are also the first serious SW/W wind events of the season - those frontal systems can bring onshore storm surf, but in their wake, offshore easterlies and lingering W swell create magic. Air temp is 18.2°C, water 18.2°C, and precipitation is 2.40mm/day. This is the classic autumn transition month: less predictable, but with the biggest increase in surf potential of the year.
