São Miguel in December
Not the best time
December wraps São Miguel in winter's gray blanket. You'll have the island mostly to yourself, but outdoor adventures take a back seat to hot springs and museum visits.
Weather
December brings winter's full return with frequent rain, strong Atlantic winds, and the year's coolest temperatures. Storms can be intense, and overcast skies are the norm. Humidity reaches 78% as the island turns thoroughly damp.

All Months
May through October offers the most reliable weather, but São Miguel's climate stays mild year-round. July and August bring the most tourists and highest prices – book accommodations well ahead. September hits the sweet spot with warm weather, calmer seas, and fewer crowds.
Winter means more rain and rougher Atlantic conditions, but temperatures rarely drop below 15°C. Hot springs feel even better when it's drizzly outside. Just pack layers – weather changes quickly in the mountains.
Avoid major Portuguese holidays like Easter week when mainland tourists flood in. Festa do Senhor Santo Cristo in May brings religious processions and packed hotels. The Azores Trail Run in October attracts serious hikers but doesn't overwhelm the island like summer crowds do.
