Conditions at Enniscrone in September
September: Autumn Awakening - First Real Groundswells
September is where Enniscrone starts to wake up. Average swell heights jump back to around 5-6ft (1.5-1.8m) and the period lifts to 10.2s, which is the threshold for powerful, long-period groundswell. The directional distribution is as good as it gets in the summer-to-autumn transition: west-northwest takes 24.6% of the wave rose, followed by west (17.6%), northwest (13.9%) and north-northwest (12.0%). These optimal directions combine for over half of all swells, and the overall energy is there to produce clean, lined-up waves on the sandbars. The Atlantic storm track hasn't fully switched on yet, but the first deep lows are starting to send precursors of the winter to come.
Wind and weather are favourable. Ideal offshore winds are at 26%, the highest of the year (tied with April and August). The wind rose is dominated by the south through west-southwest quadrant, with very few strong gales. Water temperatures are still comfortable at 15.1°C, while air temperatures average 12.9°C. Precipitation is 3.37mm/day. For many, this is the finest month of the year in Ireland: enough swell to fire Enniscrone, warm water, and a higher percentage of clean offshore mornings than either the summer or deep winter.
