Conditions at Baltrum in July
July: The Warmest Water, but the Ocean Sleeps
The North Sea hits its summer lull, but there's a subtle uptick in energy compared to June. The average swell height still reads 1.0m (3.3ft), with the shortest period of the year at 5.6s. The swell is heavily skewed towards the NW and NNW, which combined deliver a massive 36.9% of all wave energy. The flip side is that these same directions bring the prevailing summer sea breeze. Wind conditions are light, with a moderate 10-20kph sector dominating, but the ideal offshore wind is still limited to just 12% of the time. The waves become a product of the seabreeze cycle: small, weak, and often bumpy as the afternoon winds kick up. The sea surface temperature maxes out at 18.1°C, and the air can get well into the high 20s (°C). It's the perfect time to surf without a hood and perhaps just boardshorts in a thick wetsuit, but the trade-off is a total lack of power. You are squarely in 'groveling' territory. A summer storm passing through the North Sea can briefly resurrect 1.5m swells, but expect onshore winds to turn them into a mess.
