October: The North Atlantic Roars Back
October is a true turning point for Tonel. The North Atlantic roars back to life this month, bringing a sharp jump in average surf heights along the Portuguese coast. The average swell height rises to 1.8m (6ft), the average period lengthens to 11.4s, and the storm track over the North Atlantic begins to aim long-period groundswell toward the Algarve. The swell distribution is more balanced than in summer: NW at 38.0%, WNW at 17.7%, NNW at 16.5% and W at 5.9%, with WSW/SW adding another 2.7%. That means more pure W and WNW energy hitting the beach head-on. Wind conditions improve dramatically, with ideal offshore E/NE winds at 23% and the dominant NNW dropping to 28.6% as high-pressure systems become more mobile. This combination is dynamite: autumn sun, warm water (19.3°C), increasingly powerful swell and a better chance of clean offshore mornings. With air temps around 19.4°C and rain at 2.23mm/day, October is a month to watch the forecast closely-it can deliver the first excellent sessions of the season.
