Conditions at Inatel in July

July: The Summer Doldrums

July is statistically the low point of the surf year at Inatel. Average wave height is just 1-2ft (0.5m), and the average period falls to 6.0s - the shortest of any month. The swell rose is dominated by WNW at 30%, NW at 23%, and W at 18%, but almost the entire distribution sits in the 1-2ft (0.5m) range or below. In other words, the ocean is active, but it is mostly small, short-period slop with very little push.

Ideal winds drop to 11%, even though NNW is the dominant wind at 34%. The issue is that the northwesterly summer regime produces a persistent, often strong breeze that does not groom the waves effectively, and the swell is too weak to hold any real shape. Air temperatures average 23.5°C, precipitation is practically zero at 0.04 mm/day, and water temperature reaches 19.5°C. Surfers looking for waves are better off waiting for a rare S/SW pulse.
