Conditions at Thunders in July
July: The Heart of the Dry Season, Big and Consistent
July is arguably the peak of the surf year at Thunders. Average swell height reaches 1.7m (5.6ft), tied for the highest of the year, and the average period maxes out at 14.3s. Swell direction is split between a dominant 60.4% SSW and a solid 29.3% S, with SW providing the rest. That spread means the ocean is almost never short of energy, and the directional mix offers both waves wrapping in from the SSW and the occasional straighter S pulse.
Size distribution is what makes July special: 60% of waves break in the 1.5-2m (5-6.5ft) zone, while another 14.7% reach 2-2.5m (6.5-8ft), and a whisper of waves exceeds 2.5m (8ft+). The winds are at their most reliable too - ideal surfing conditions 55% of the time. Strong SE trade winds at 30.6% SE can blow some texture into the surface on the heaviest afternoons, but mornings with lighter ESE to SSE flow and a fading monsoon sea are pure magic. Air temperatures hold near 27.7°C, water at 29.3°C, and rain is a low 5.69mm/day. This is the month to plan a chase around pulses of SSW groundswell.
