October: The Roar Returns
October is when the North Atlantic roars back to life. Average surf height jumps to 6.5ft (2.0m), average period climbs to 11.3s, and the ideal-wind percentage leaps to 40 percent. The season's first strong extratropical storms develop over the Atlantic and aim long-period WNW and NW groundswell at the Portuguese coast; NW (31.3 percent) and WNW (22.2 percent) lead the swell distribution, with a solid 8.6 percent coming from the west. The wind pattern becomes more variable and more favorable - southerly flow increases, offshore E/ENE winds appear more often, and the persistent summer northerly weakens. Water temp is still pleasant at 17.5C (64F), air temps average 17.0C (63F), and rainfall picks up to 3.87mm/day. The combination of building swell, longer periods and cleaner winds makes October one of the best all-round months to score Mira.
