Conditions at Tywyn in November
November: Prime Time, Punch and Power
November locks in Tywyn's best season. Average wave height reaches 3.3ft (1.0m) and the average period comes in at 7.7s, but the real story is the distribution. WSW at 30.4 percent and SW at 21.0 percent remain the leading swell directions, while W and WNW add 22.1 percent. Critically, the 5ft (1.5m) and above class accounts for more than 16 percent of all observations, with a healthy amount of 2-2.5m (6.5-8ft) swell already showing up. The lows that spin off the North Atlantic are now generating legitimate surf for Tywyn's west-facing beach.
Wind quality also peaks in November, with ideal conditions at 12 percent, tied for the best of the year. Offshore directions E, ESE, NE and ENE are more common than in summer, but SW and WSW winds still blow onshore about a third of the time. The Atlantic also turns wetter and cooler: air temperatures drop to 9.5°C, water temperature falls to 11.7°C, and precipitation rises to 4.16 mm/day. For consistent, punchy waves and the best chance of an offshore wind day, November is a serious contender for Tywyn's best surf month.
