If you only need Tbilisi climate: monthly averages, the figures and table here are the whole story. Tbilisi runs from 1.0 C in Jan to 26.0 C in Jul, a swing of 25.0 C. Rain is spread through the year, with May the wettest month at 1.88 mm/day and Dec the driest at 0.56 mm/day. Taken together that is roughly 377 mm of rain a year for the grid cell.

What the Tbilisi climate table shows
Values are multi-decadal climatological averages for the 41.6914, 44.8341 grid cell, not a single year. Rain is the daily mean, so a value of 2.00 mm/day is about 60 mm across a 30-day month. Averages smooth over extremes, so use them for planning rather than for what to pack for next Tuesday.
Frequently asked questions
Is Tbilisi climate data a forecast?
No. These are multi-decadal averages for the grid cell, not a prediction for any particular year.
Why do the numbers differ from a weather app?
An app shows one location on one day. These are long-run averages, so they smooth out single hot or cold spells.
