Traveller notes on La Serena in October
Other months in La Serena
La Serena's forum is clear that hot February days don't mean warm water — regulars describe the sea as frigidly cold with powerful currents that keep most people out of it altogether, even at the height of Chilean summer. It's peak vacation season for Chileans too, so accommodation books up well ahead.
