    The nortada

    15 Jun – 15 Sep · usuallyWind seasonRisk

    The north wind gets up most summer afternoons, which is why Guincho belongs to kitesurfers and why the sheltered town beaches fill instead. Mornings are the calm half of the day.

    The Atlantic upwelling keeps this coast cold well into summer and it only comes round in August and September. The bay beaches are always a little warmer than Guincho.
