Conditions at Amoreira in October
October: The North Atlantic Roars Back
The autumn transition kicks into high gear. Average surf height climbs back to 6ft (1.9m) and the average period reaches 11.5 seconds. The swell direction is well spread across the exposed window: NW 40.3 percent, WNW 20.3 percent, NNW 11.9 percent and W 5.8 percent. These are proper groundswells generated by the first intense extratropical storms of the season, and the west-northwest-facing beach lights up with power and consistency. Ideal wind windows improve to 29 percent, and the wind distribution becomes more variable. NNW is still the most common direction at 23.6 percent, but there are more southerly and easterly influences than in summer, creating cleaner, more manageable conditions. Water temperature is still warm at 18.6°C, air has cooled to 18.5°C, and rain is on the increase. This is one of the best months to score powerful surf without the full-on winter cold.
