This is the short version of Columbus climate: monthly averages, with the monthly detail underneath. The gap between Jan and Jul is 26.0 C here: -2.6 C against 23.4 C. No month dominates: the wettest is Jun at 3.45 mm/day, the driest Jan at 2.09 mm/day. Taken together that is roughly 984 mm of rain a year for the grid cell. The build runs on a schedule and caches the last good response, so the numbers stay put even when the upstream API is having a bad day.

What the Columbus climate table shows
Values are multi-decadal climatological averages for the 39.96118, -82.99879 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
Does Columbus get the same every year?
Close to it. Averaging decades smooths variation, so treat these as typical rather than guaranteed.
