Conditions at Kirra in October
October: The North Wind Machine Takes Hold
October is the roughest month of the year statistically. The ideal wind percentage bottoms out at 34%, while NNW wind blows a massive 22% of the time. Swell period slumps to 7.4s and the average height is 1.0m (3.3ft). The swell direction is concentrated between E (23%), ESE (19%), ENE (17%), SE (14%), NNE (13%) and NE (10%) - plenty of east and even northeast energy, but the north wind makes it difficult to use at Kirra. The north-facing beach is exposed to the NNW fetch, so the surface turns to chop and the short-period swell lacks bite. Occasional E/NE swells from tropical systems or a strong S change can provide brief windows of 3-5ft (1-1.5m) surf, but October is a month to watch the synoptics and time the changes. Water temperature is 21.5°C, air temperature averages 21.2°C, and rain is 2.50mm/day.
