Conditions at Isla Grande in October
October: Fickle Sizes, Clean Lines
October is a transition month, and the swell direction becomes a little more mixed - NE drops to 70.5%, with NNE at 8.8% and a noticeable bump in N and NNW components. The average swell height remains a small 0.8m (2.5ft) and the period shortens to 7.0s, so wave quality depends heavily on the local wind. The good news is that ideal offshore wind still occurs 40% of the time, with each SW, WSW, and W direction contributing over 7%. This means you can often find clean, if modest, 2-3ft (0.6-0.9m) waves. Water temperature is a toasty 29.3°C, and rainfall is high at 7.97 mm/day. October requires a more patient approach - wait for the right swell pulse and you might be surprised, but size is definitely limited.
