Conditions at Cabedelo do Douro in January
January: Midwinter Power at the River Mouth
January is the heart of winter and the rawest statistical month at Cabedelo do Douro. The average swell height sits near 6ft (1.8m) with a long average period of 12.7s, and swell direction data is heavily loaded in the optimum quadrant: WNW leads with 46.7 percent, followed by W at 15.8 percent and NW at 16.1 percent. That means roughly eight out of ten wave observations are from the WSW-to-NW range the sandbar loves. The height distribution shows a lot of energy in the 3.3-8ft (1-2.5m) range, including a serious dose of 6.5-8ft (2-2.5m) groundswell, so Cabedelo frequently has power.
Wind-wise, the east and southeast quadrants (ENE, E, ESE, SE) are very active, and with 47 percent ideal conditions, this is one of the most consistent months for clean, offshore surf. Expect 10.4°C air and 13.6°C water, plus 4.24mm/day of rain, often linked to passing fronts. When the wind goes easterly behind a low, the river-mouth sandbanks groom the long-period WNW swell into proper barrels; when it turns westerly, the same swell becomes a close-out.
