October: Winter's First Breath
October is when the North Atlantic and English Channel storm track begins to stir in earnest.

SW and WSW swells lead the rose at 15.1% and 12.3%, while the offshore wind share reaches the joint best of the year at 7%. That means occasional mornings with a southern offshore breeze, more glassy surfaces, and punchy 3ft (0.9m) waves from the N/NNW window. Air temperature cools to 12.8°C, water is still 15.5°C, and precipitation begins to increase at 2.61 mm/day-a solid month for catching one of Calais' better days.
