Conditions at Supertubos in July
July: The Summer Slump
July is the slowest and most challenging month for Supertubos. Average swell height bottoms out at 4.9ft (1.5m) and the average period is a weak 8.6s. Almost all of the energy arrives from the NNW (52.4%) and NW (31.7%), with only 10.1% from WNW - meaning the waves tend to be windswell and short-period. The wave-height distribution is concentrated in the 1-1.5m range, with a meaningful share of 1.5-2m sets, but those sets rarely have the power to penetrate the sandbar. The wind is offshore only 19% of the time; the NNW thermal (62.9% of all wind) dominates the coast, often exceeding 20-30kph. That combination of small swell and strong north-northwest wind creates messy, bumpy conditions that are best avoided unless you're desperate for a grovel. Air temperatures peak around 19.4°C and the water is a warm 18.1°C, so the beach is inviting, but the surf is not.
