Conditions at Thorli in August
August: Late Summer Pulses
August holds onto summer's friendly winds while small pulses of new autumn energy begin showing up. Average swell height is still a modest 4-5ft (1.5m), and period is 8.5 seconds, but there is a little more push than July. Ideal offshore wind remains high at 36 percent; SE (9.8%), SSE (7.9%) and ESE (7.4%) are the onshore wildcards, while west/northwest winds are common enough to keep the beach clean. The favorable east-southeast wave window makes up roughly 15 percent of the total, with SE (9.1%) and ESE (4.3%) generating a broad mix of 0.5-2m (2-6ft) waves. SW (21.5%) and SSW (15.6%) still dominate the background Atlantic swell, but they lack the power to make Thorli fire. Water temperature hits its annual high of 11.6°C, air temperature averages 10.3°C, and precipitation picks back up to 4.18 mm/day. August offers a forgiving transition before the North Atlantic starts to rumble.
