When to go to Valdes Peninsula and Atlantic Patagonia
December - February
These are the summer months, with the hottest temperatures reaching 30°C and little rainfall. December is the end of the breeding season for southern right whales, while orcas and penguins will also be visible in the waters. This is the busiest month for visitors as it coincides with the Latin American holiday season.

September - November
Temperatures begin to warm up and rainfall decreases, making this a pleasant time to visit weather-wise. These spring months are also the best for wildlife watching - look out for southern right whales and elephant seals, and the fluffy penguin chicks which first emerge in November. For those interested in the Welsh colonist community of Patagonia, late October sees the traditional celebration of Eisteddfod de Chubut.
