Conditions at Rosa in October
October: Spring Size with a Summer Chop
October is a transitional month where size remains good but quality takes a hit. The average swell height is still a strong 1.4m (4-5ft), but the average period drops to 8.6s, indicating more windswell and shorter-period energy mixed in. The wave rose is dominated by E (26%), ENE (20%), ESE (19%) and SE (14%), with a solid share of 1-1.5m (3-5ft) and 1.5-2m (5-6ft) waves. There is still plenty of size, but it often lacks the punch of the winter months.
Wind becomes the limiting factor once again. Ideal conditions fall to just 25%, with NNE (24%) and NE (19%) trades prevailing and only modest SSW (11%) and SW (8%) counterbalance. The offshore W/NW flow is increasingly rare. Water temperature warms to 20.1°C, air averages 18.9°C, and rainfall comes in at 4.64 mm/day. October is worth a look if you are chasing size, but expect some lumpy, trade-blown days.
