Climate overview
Temperature
The coldest monthly mean is -16.6 °C in January, while the warmest is 19.0 °C in July. These are monthly mean temperatures, not daytime highs, so they describe the average conditions of each month rather than the upper temperatures visitors might experience on individual days. The unweighted mean across the monthly means is 1.6 °C; it summarizes the month-level figures without weighting them by the number of days in each month.
Rain
Mean daily rainfall reaches its monthly high of 2.40 mm/day in July and its low of 0.01 mm/day in January. The broader month-level summary is an unweighted mean of 0.97 mm/day. These are daily averages, not monthly rainfall totals: the lower average can help identify an option for visitors prioritising less rainfall, but it does not guarantee dry days or indicate how often rain occurs.
Sunshine
Mean daily sunshine is highest at 12.98 hours/day in June and lowest at 1.48 hours/day in December. The unweighted mean across the monthly means is 7.06 hours/day. These figures can help with planning outdoor time around typical sunshine duration, but they measure average daily sunshine, not day length, and do not promise clear skies on a particular date.
Snow
Mean daily snowfall reaches its reported monthly high of 11.03 mm/day in December; the unweighted mean across monthly means is 4.25 mm/day. These daily averages describe amounts, not the number of snowy days, snow depth or how long snow cover lasts, so they cannot establish what ground conditions a visitor will find.
Best Travel Time Guide for Tomsk (Sibiria), Russian Federation: Ideal Seasons and Weather Insights
For visitors prioritising cooler monthly average temperatures, January is the relevant option, with a monthly mean of -16.6 °C; this is not a forecast of daytime temperatures on travel dates. Those planning outdoor sightseeing around sunshine may instead look to June, when mean daily sunshine is 12.98 hours/day, while remembering that sunshine duration is not day length or a guarantee of clear weather. If lower average rainfall is the priority, January is the conditional choice, with mean daily rainfall of 0.01 mm/day. For rain preparation, note that the highest monthly mean daily rainfall is 2.40 mm/day in July; pack for changeable conditions rather than treating the average as a prediction for any given day. These criteria point to different considerations, not a single universally best time to visit.
