Conditions at Amoreira in January
January: Midwinter Muscle from the Atlantic
This is the heart of the Portuguese winter. Average surf heights reach 8ft (2.5m) and the average period hangs at a powerful 13.1 seconds, so most days have proper long-period groundswell rolling into the west-northwest-facing beach. The wave rose is dominated by NW and WNW swell, at 26.3 percent and 18.5 percent respectively, with a useful NNW contribution as well. These are deep-water groundswells generated by intense extratropical lows pressing into the eastern Atlantic. The main issue is wind: NNW winds blow 17.5 percent of the time, and the entire N to NE quadrant is prominent, so many arrivals are chopped up. Still, 34 percent of hours are classed as ideal wind windows, often when high pressure over Iberia settles in and provides lighter winds. Water temperature is 15.5°C, air temperatures average 11.1°C, and rain is frequent. Bring the 4/3, stay patient, and hunt the clean winter windows.
