Climate Chart of San Miguel de Tucumán, Argentina

Climate overview

Temperature

The warmest monthly mean temperature occurs in January, at 24.9 °C. This is a monthly mean, not a typical daytime high, so it does not show how warm an individual afternoon may become. The lowest monthly means are shared by June / July, at 12.5 °C. Visitors who prefer cooler monthly averages may use this as a guide when choosing dates, while keeping in mind that a monthly mean does not describe day-to-day swings or guarantee a particular temperature during a visit. Across the calendar-month means, the unweighted mean is 19.2 °C; it is not a day-weighted annual average.

Rain

Mean daily rainfall reaches its highest monthly level in January, at 6.74 mm/day. This is an average daily amount, not a monthly total, and it does not reveal how often rain falls or whether a particular day will be wet; visitors during this period should allow for rain in their plans. The lowest monthly mean daily rainfall is in August, at 0.29 mm/day. That month can be a conditional option for visitors prioritising lower average rainfall, but the figure does not guarantee dry days or quantify rain frequency. The unweighted mean of the monthly daily-rainfall averages is 2.90 mm/day; this is not a monthly accumulation or a day-weighted annual figure.

Sunshine

Mean daily sunshine duration is highest in January, at 10.84 hours/day, and lowest in May, at 7.42 hours/day. These averages can help with planning for outdoor sightseeing, but sunshine duration is not the same as day length and cannot guarantee clear skies on a given date. The unweighted mean across the monthly sunshine averages is 9.24 hours/day per day, offering an overall reference rather than a promise about daily conditions.
