Conditions at Guincho in July
July: Peak Summer Slump
July is the slowest month of the year at Guincho. Average swell slips to 4-5ft (1.2-1.5m), the period bottoms out at 8.5s, and the swell rose is dominated by NNW at 54% and NW at 33%. This is pure summertime windswell, almost always generated by the same summertime wind that makes it unrideable. NNW winds blow 65% of the time, and ideal wind for Guincho registers just 2% - the worst of the year. The Portuguese nortada is in full force, churning up the beach and keeping wave quality low even when the waves themselves look inviting. Small windows can happen very early in the morning or when the wind briefly veers toward the east, but the surface is quickly chopped out. Water temperature reaches 17.9°C, air averages 20°C, and blue skies and dry conditions are the norm. This is definitely the season for longboards, bodyboards, or anyone content with slow, sectiony walls before the wind takes over.
