Conditions at Llangennith in July

July: The Flattest Month of the Year

July is the low point for Llangennith. The average swell height bottoms out at 2-3ft (0.7m), the average period drops to 7.4s, and ideal offshore wind is observed only 3% of the time. Swell direction is still dominated by WSW at 43.8% and W at 33.8%, but the distribution is heavily skewed toward the 0-3ft (0-1m) range. There is rarely any real push, and what does arrive is mostly short-period summer windswell. The wind rose is split between moderate W/SW breezes and a higher share of NW/NNW winds, but the key number is the tiny 12% contribution from the offshore NE-E sector. Afternoon westerly sea breezes are the norm, and with air temperatures at 16.0°C and water at 16.9°C, the beach is more about holidays than waves. If you are determined to surf, go small-wave hunting with a high-volume board, pick a dawn glass-off, and enjoy the warmest, most forgiving conditions of the year.
