Conditions at Nazare in July
July: Peak Summer Smallness
July is the quietest month of the year on average. Combined swell height averages just 4ft (1.3m), and the period drops to 8.7 seconds, putting most waves in the small, groveling to fun-sized categories. The swell is nearly all from the north: NW 50.4 percent, NNW 31.1 percent, WNW 15.1 percent, and true W only 2.0 percent. These are classic summer NW pulses, but with such short periods they struggle to generate quality at Nazare. The wind is the bigger issue: ideal offshore wind occurs only 26 percent of the time, while NNW blows an incredible 63.7 percent of the time. That keeps the surface bumpy and cross-shore for much of the day. Air temp averages 19.4°C, water temp 18.0°C, so it feels like summer, but the surf is better suited to a longboard than a big gun.
