The entire region is in the rain-shadow of the Andean Cordillera, making for a cool, dry climate with temperatures averaging 66°F in January and 45°F in July. It's very windy; bring extra warm clothes regardless of the season.

The most popular time is June through December, when southern right whales are mating and raising offspring at Península Valdés. But August to September is when there are whales, low-season prices and there are fewer people.
