What the Aguascalientes climate table shows
Values are multi-decadal climatological averages for the 21.88262, -102.2843 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 Aguascalientes get the same every year?
Close to it. Averaging decades smooths variation, so treat these as typical rather than guaranteed.
