Porto Santo lies northeast of Madeira and is a different island in almost every way: flat, dry and golden, with nine kilometres of sand running along its south coast. That beach is the reason people come, since Madeira itself has almost none. Christopher Columbus lived here, and the house that bears his name is a museum in the town. The sand has long been considered good for aching joints, and people bury themselves in it as a treatment.

The climate is mild and dry all year, with summer afternoons around 24–26 °C and winter days near 18–19 °C. Rain is scarce and falls mostly in short winter spells. Surrounded by deep Atlantic water, the sea changes slowly and gently, running roughly 19–23 °C across the year, which makes swimming comfortable in months when the mainland is out of the question.

When is the sea warmest in Porto Santo?

From August to October, when the water reaches its high of about 23–24 °C. The low point comes in February and March at around 19 °C, still warmer than the mainland manages in midsummer. The seasonal swing here is one of the smallest in Portugal.

How do you get to Porto Santo?

By ferry from Funchal, a crossing of about two and a half hours, or by a short flight from Madeira, with direct flights from the mainland in season. The ferry can be rough in winter swell. Most visitors stay several days, since the island is small and very quiet once the day boat leaves.

What is Porto Santo like compared with Madeira?

Flatter, drier and far quieter. Madeira is green, mountainous and rocky at the shore, while Porto Santo is essentially one long sandy beach with a small town behind it. If you want a beach holiday in the archipelago, this is where it happens.
