Conditions at Guincho in October
October: The Season Switches On
October is the true kickoff of Guincho's high season. Average swell jumps to 6-7ft (1.8-2.1m), the period reaches 11.4s, and the distribution favours NW at 30.6%, WNW at 18.6% and NNW at 19.5%. This is the first month where the North Atlantic low-pressure track consistently aims energy toward Portugal, and the beach starts seeing longer, more organised groundswell. The wind regime also relaxes from summer extremes, with ideal offshore conditions up to 20%. NNW winds still blow 22.8% of the time, but there are many more windows with offshore ENE-E-ESE flow, particularly in the days after a cold front moves through. Water remains warm from summer at 18.4°C, air temperatures sit near 18°C, and rainfall increases to 2.5mm per day as autumn storms arrive. If you time a new W/NW swell with a light easterly, October can serve up some of the most underrated surfing of the year.
