Conditions at Killer Point in August
August: Same Summer Rhythm, Slightly Longer Periods
August mirrors July, with an average swell height of 1.6m (5.2ft) and an average period of 8.2s. The direction is almost exclusively NNW at 93.8% of the wave distribution, with NW contributing 3.2%. Height-wise, the 1-1.5m and 1.5-2m ranges dominate, so there is no shortage of waves, just a shortage of quality. The energy is mainly short-period and heavily affected by the wind that created it.
Offshore winds remain scarce at 22%. NNW and NW winds together account for more than 60% of the observations, meaning Killer Point will often have a bumpier texture and reduced shape. Still, late August can sometimes catch the first signs of tropical storm activity in the eastern Atlantic, delivering an occasional longer-period pulse. Air temperatures peak around 23.4°C, water reaches 18.1°C, and precipitation is almost nonexistent at 0.14mm/day. It is definitely a pick-your-window month.
