Best time to visit Antofagasta
Chile · 20-year averages
Antofagasta has no real season. The best month scores 100 and the worst 87, a spread of just 13 points, so the honest answer to "when should I go" is whenever the flights are cheapest. 9 of the twelve months sit within ten points of the best, so there is more than one right answer.
February is the warmest month at 22.5 °C and July the coolest at 16 °C — a 6.5 °C spread across the year. It never reaches 30 °C in an average year, which takes heat off the list of reasons to avoid any particular month.
Rain is spread evenly through the year — between 0 and 1 wet days in every month — so there is no dry season to aim for and no wet one to dodge. Whatever you plan, the odds of rain are much the same.
The sea is comfortable for swimming in January to March — 22.4 °C at its warmest against 15.3 °C at its coldest. The water peaks a month or two after the air does, so the best swimming falls later in the year than the best weather. Daylight runs from 10.7 hours in winter to 13.6 in summer, enough to notice on a sightseeing itinerary.
The three strongest months are January, March, December. The one to think twice about is August. Each month below has its own page with rainfall reliability, extremes, daylight, sea temperature and crowd levels.
