August: Tropical Season, Wrong Angles
August remains deeply trapped in the low surf season. Average height is still 1ft (0.3m), period is 3.2 seconds, and ENE swell accounts for 54% of all wave energy. The share of NE swell reaches 16%, but none of that is favourable for this north-northwest-facing coastline. The N/NNW sector contributes just over 8% of the total, virtually all under 0.5m.
Winds are dominated by E/ENE/ESE 69% of the time, ensuring plenty of chop. Offshore S/SW/SSW/WSW winds sit near 6%, so truly clean sessions are extremely rare. Water temperature is at its yearly peak, 30°C (86°F), air holds around 29°C (84°F), and rainfall remains high at 2.86 mm/day. The tropical cyclone season is underway, but the typical E/SE approach angle of these systems does not translate into quality groundswell at Sun Beach; it is more likely to produce storm surf from a poor direction or just pile up the clouds.
