Conditions at Contreiras in October
October: Prime Time Begins
October is when the North Atlantic roars back to life and Contreiras enters its best window. Average swell height jumps to 2.0m (6.6ft) and average period climbs to 11.5s, meaning the onset of powerful, long-period groundswell. Directionally, it is almost exactly what the spot wants: NNW at 35.4 percent, NW at 18.0 percent, WNW at 4.6 percent, with N and NNE both in the 8 percent range. The swell distribution is loaded with 1.5-2.5m (5-8ft) waves, and there are already hints of overhead-plus sets. Wind statistics are the best of any month, with ideal offshore conditions from the SSW-SW-WSW-W quadrant reaching 22 percent. The persistent NE flow is weaker, and the increasing frequency of frontal passages brings more south and west winds, offering cleaner conditions more often. Air temperatures remain pleasant at 17.6-24.7°C, water temperature is still warm at 22.8°C, and precipitation jumps to 1.27mm/day. October is the classic month to score warm water, fresh autumn groundswell and reasonably clean winds all in the same day.
