Conditions at Brandon Bay in October
October: The Atlantic Roars Back
October is a true turning point for Brandon Bay. The average swell jumps to 4.5ft (1.4m) and period reaches 11.0 seconds, while the percentage of 5-8ft (1.5-2.5m) surf starts to climb. The waverose is filled with WNW (26.9%), W (25.5%), WSW (13.9%) and NW (13.4%) - a classic autumn mix for this southwest-facing beach. The Icelandic Low strengthens and the storm track shifts south, generating pulses of long-period W and WSW groundswell that arrive at the Irish coast. Onshore winds remain common, with SW (10.4%) and SSW (10.3%) leading, but ideal offshore flow holds at 25 percent and the longer period can override some of the chop. Water temperature is 13.4°C, air 12.1°C, rainfall 3.93 mm/day. This is the month to start charging; October will put the winter stoke back in your system.
