Conditions at Murtosa in January
January: Midwinter Power
January is the heart of the Portuguese winter and Murtosa feels the full force of the North Atlantic. The average swell stands at 2.6m (8.5ft) with a 12.8s period, meaning conditions are often powerful and lined up. Energy from the optimal WNW and NW quadrants dominates: WNW accounts for 22.1% of observations, NW adds 17.2%, and W contributes another 6.8%, giving the beach plenty of clean, open-ocean groundswell. The most common wave-height class is a solid 2-2.5m (6.5-8.2ft), and the over-2.5m (over 8.2ft) category is well represented from WNW and NW. Offshore E/ENE/ESE/SE flow is common enough to produce an ideal-window frequency of 48%, though NNW winds are the main spoiler when they build. With average air temperatures around 10.2°C, precipitation at 3.93 mm/day and water temperature near 13.7°C, this is serious winter surf: bring the thickest wetsuit in the quiver.
