Conditions at Porzcarn in August
August: Small but Not Dead
August is Porzcarn's warmest month, with air around 17.7°C and water peaking at 17.7°C, but the surf remains small. Average height is 3ft (1m), average period is 8.8s, and ideal wind time is 15%. The waverose is top-heavy with WNW (35.4%) and W (33.1%) swell, which confirms the spot continues to see constant, though generally weak, energy. Most of this is in the 2-5ft (0.5-1.5m) range, with occasional 5-6ft (1.5-2m) sets. Onshore W-NW winds still rule more than 40% of the time, so surface conditions are often the deciding factor. Precipitation remains low at 1.73 mm/day. With the warmest water of the year and slowly rebounding autumn lows, a trailing front can occasionally fire up a clean late-August swell; otherwise bring a grovel board and enjoy the beach days.
