Conditions at Comporta in October
October: The Atlantic Roars Back
The North Atlantic roars to life during October, and Comporta feels it immediately. Average swell height jumps to 5ft (1.5m), and the period lengthens to 11.3 seconds. NW and WNW swells are almost perfectly balanced at 35 and 33 percent, while W swell pushes in at 12.5 percent, giving the beach a broad, powerful swell window. These are the first serious groundswells of the season, generated by developing extratropical cyclones in the mid-Atlantic. Ideal wind percentages rise back to 40 percent as the synoptic pattern becomes more mobile, though the dominant NNW flow still has a say. Water temperature holds at a warm 18.3°C, air temperature averages a mild 18.2°C, and rain begins to return with 2.40 mm/day. October is one of the best combinations of size, period and still-warm water in the whole year.
