Everything below is collected in one spot so you do not have to cross-check Jacksonville climate: monthly averages by hand. The gap between Jan and Jul is 16.4 C here: 11.2 C against 27.6 C. No month dominates: the wettest is Jun at 6.24 mm/day, the driest Nov at 1.77 mm/day. Taken together that is roughly 1,283 mm of rain a year for the grid cell. Because each page is rebuilt independently, one unavailable upstream never takes the rest of the site down. Exact monthly values are in the table; links below cover adjacent locations and years.

What the Jacksonville climate table shows
Values are multi-decadal climatological averages for the 30.33218, -81.65565 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

Rain is recorded as a daily mean, so 6.24 mm/day is roughly 190 mm across a 30-day month.
Does Jacksonville get the same every year?
Close to it. Averaging decades smooths variation, so treat these as typical rather than guaranteed.
