Conditions at Arica in October
October: Spring Swell with a Side of Breeze
October is a transition month. The average swell height eases to around 5-6ft (1.7m) with period still a solid 13.4s, so there is plenty of power in the water. The 5-6.5ft (1.5-2m) range remains the biggest share at 45.4%, while 6.5-8ft (2-2.5m) makes up 18.4%. Directionally, it is a near exact split between SSW (47.0%) and SW (49.9%), meaning the southwesterly groundswell train is still running strong. Winds, however, keep the westerly component high: W (51.3%) overtakes WSW (44.8%), extending the late-winter pattern. None of it is offshore-the ideal score remains 0%-and the onshore breeze is a little more active, with WSW/W 10-20kph flow increasing. Air temps rise to 17.8°C and water to 16.6°C. Surfable, but you'll be trading a little power for increasingly bumpy spring conditions.
