Climate Chart of Columbia, USA
Monthly data: Temperature °C, Rain (mm), Sunshine (h) · 2013–2023
For Columbia, USA, the climate data describe conditions across 2013–2023. Monthly mean temperatures range from January at 1.9 °C to July at 26.0 °C, giving a sense of the shift between the coolest and warmest monthly averages. Rainfall and sunshine also vary by month, while the snowfall figures record daily mean amounts rather than snowfall totals or the number of snowy days. Together, these measures offer useful context for planning, but monthly averages do not predict conditions on a particular day.
Climate overview
Temperature
Temperature varies markedly across the year in the monthly averages: the coolest is January at 1.9 °C, while the warmest is July at 26.0 °C. These are monthly mean temperatures, not daytime highs, so they describe the average level rather than the warmth visitors can expect at a particular time of day. Across the calendar-month means, the unweighted mean is 14.1 °C. It provides a broad summary, but does not represent a day-weighted annual average or show the range of temperatures within any month.
Rain
Mean daily rainfall reaches its highest monthly average in July at 5.36 mm/day; visitors then may wish to plan for wet-weather interruptions and bring suitable rain protection. The lowest monthly average is in January at 1.90 mm/day, making that a conditional option for those prioritising lower average rainfall. The unweighted mean across monthly daily-rainfall averages is 3.42 mm/day. These are daily mean amounts, not monthly totals, and the averages do not indicate how often rain falls or guarantee dry weather in the lower-rainfall month.
Sunshine
Mean daily sunshine is highest in July at 11.41 hours/day and lowest in December at 5.47 hours/day. These figures can help with planning outdoor time, but sunshine duration is not the same as day length and does not promise clear skies on any given day. The unweighted mean across monthly sunshine averages is 8.37 hours/day per day, a broad reference rather than a forecast for individual dates.
Snow
Mean daily snowfall is highest in January at 4.47 mm/day. This records an average amount, not the number of snowy days, snow depth or snow cover, so it cannot establish whether snow will be present during a visit. The unweighted mean across monthly daily-snowfall averages is 1.14 mm/day; it summarizes the monthly means without describing conditions on a particular day.
Best Travel Time Guide for Columbia, USA: Ideal Seasons and Weather Insights
If cooler monthly-average temperatures are your priority, January is the relevant point of reference, with a mean of 1.9 °C. For lower average rainfall, January is the conditional option at 1.90 mm/day; these criteria identify different aspects of travel weather, not a single universally best time to visit. For rain preparation, note that mean daily rainfall is highest in July at 5.36 mm/day. A monthly average cannot tell you how frequently rain occurs or whether a particular day will be wet, so flexible plans and rain protection remain sensible.
Visitors planning outdoor sightseeing around sunshine may find July useful to consider, when mean daily sunshine is 11.41 hours/day; December has the lowest monthly mean at 5.47 hours/day. These are averages of sunshine duration, not guarantees of clear weather or measures of daylight length. Mean daily snowfall is highest in January at 4.47 mm/day, but this average does not establish snowy-day frequency or snow cover. Treat it as background climate information rather than a guide to whether snow will affect your plans.
