Conditions at Pedra Branca in October
October: The North Atlantic Roars Back to Life
The North Atlantic begins to roar in October, and Pedra Branca feels it immediately. Average wave heights jump to 6-7ft (1.8-2.1m), and the average period runs 11.4s. The first serious extratropical storms of the season send long-period swell into the west-facing beach, with NW contributing 30.6% of all swell observations, WNW 18.6%, and NNW 19.5%. Combined with 6.7% west swell, the beach is once again sitting directly in the firing line of the Atlantic.
The wind regime also becomes more promising. Ideal surf wind returns to 21%, and offshore ENE/E/ESE/SE flow accounts for nearly 11% of all observations. As high pressure drifts south and lows track across the North Atlantic, the stiff early-autumn northerlies begin to relax, opening up more clean windows. Air temperatures cool to 17.6°C, water remains warm at 18.1°C, and rainfall increases to 2.62mm/day. October is often the pick of the year: first-rate winter swell with lingering warm water and a better chance of glassy winds.
