The Portuguese west coast summer classic.
Portuguese water
The west coast rarely leaves 14–19°C — a 3/2 in summer and a 4/3 in winter cover most sessions. The Algarve reaches 21–22°C in late summer; the North drops to 13–14°C in March, the coldest water month (not January — the sea lags the air by about two months).
Wind steals more heat than the water does: on a windy day, dress as if the water were 1–2°C colder.
