Climate Chart of Santiago, Chile

Climate overview

Temperature

Monthly mean temperature is highest in January, at 22.0 °C, and lowest in July, at 9.9 °C. These are averages for each month rather than daytime high temperatures, so they describe the broad thermal pattern without indicating the full range visitors might experience during a day. Across the calendar-month means, the unweighted mean is 16.0 °C. It is a useful broad summary, but it is not a day-weighted annual average and does not replace the month-specific figures when choosing travel dates.

Rain

The mean daily rainfall reaches its highest monthly average in June, at 2.22 mm/day; this is a daily mean, not a monthly rainfall total. Visitors planning for that period may want rain-ready clothing, while the figure alone cannot show how often rain falls or whether a particular day will be wet. For visitors prioritising lower average rainfall, March is the lowest-rainfall month in these figures, with a mean daily amount of 0.09 mm/day. This is a conditional option rather than a promise of dry weather; the unweighted mean across monthly daily-rainfall averages is 1.00 mm/day.

Sunshine

Mean daily sunshine is highest in December, at 12.99 hours/day, and lowest in June, at 6.92 hours/day. These averages can help with planning outdoor sightseeing, but sunshine duration is not the same as day length and does not guarantee clear conditions. The unweighted mean of the monthly sunshine averages is 10.02 hours/day per day. Treat it as a year-wide summary, not as a forecast for a particular visit.

Snow

The highest monthly mean daily snowfall is recorded in July, at 0.35 mm/day, while the unweighted mean across monthly averages is 0.04 mm/day. These amounts do not establish how many days have snow, snow depth or snow cover, so they cannot determine conditions for skiing or other snow-dependent plans.
