Conditions at Praia da Vieira in January
January: The Midwinter Powerhouse
January is statistically one of the heaviest months of the year at Praia da Vieira. The average swell height sits at 8ft (2.4m) with a long-period 13.1s, and the dominant swell directions are WNW and NW, combining for nearly half of all wave energy. With the beach pointing into the west-northwest, these are the pulses that unload most consistently. A significant chunk of the swell arrives in the 5-8ft (1.5-2.5m) range, but there are also pockets of overhead-plus and even XL surf when the North Atlantic low-pressure train lines up just right. The good news is that 37% of the time the wind is offshore from the ONO-O-OSO-SO (ENE-E-ESE-SE) quadrant-among the highest of the year-so the conditions can be world-class between winter storms. When lows pass to the northwest, expect W or WSW swells with fresh onshore winds, but when a high pressure ridge builds over the continent and the easterly flow kicks in, Praia da Vieira produces long, racy, hollow peaks off the beach. Water temp drops to 14.0°C, air temps average just 9.7°C and with 3.43 mm/day of precipitation, bring the 5/4 hooded suit and warm-up layers.
