Patagonia: Get wise about the weather

Late November to early March—summer in the southern hemisphere—is high season in Patagonia. Demand for accommodations is highest in January and February, so reservations are vital. Summer weather is pleasantly cool. Bring an extra layer or two, even when the sun is shining. Windbreakers are essential. On or near Antarctic waters, stiff breezes can be biting. In spring (September to November) and fall (March to May) the weather is usually delightfully mild, but can also be downright cold. The region goes into virtual hibernation in the winter months of June, July, and August.
