Conditions at Troia in July
July: The Summer Doldrums
July is the lowest energy month of the year for wave height, with an average swell height of 3-3.5ft (1.0m) and the shortest period of the entire year at 8.7s. The wave rose is staggering: NW alone accounts for 67.3% of all swell directions and WNW another 23.8%; the W window collapses to just 3.3%, and there is virtually no SW component. This is pure northwesterly windswell and short-period groundswell - soft, crumbly and heavily wave-period-limited.
The wind picture is equally one-dimensional. NNW dominates at 47.3%, NW adds 19.9%, and WNW adds 10.1%. Offshore NE/E wind is almost zero, though ideal wind is still measured at 28% on lighter days. On the plus side, air temperatures are warm (23.3°C), water is 17.3°C, and rain is nearly non-existent (0.10mm/day). For surfers, it's a month for high-tide foam rides and longboards, with occasional clean small mornings before the afternoon northerly howls.
