What the Porto climate table shows
Values are multi-decadal climatological averages for the 41.1579, -8.6291 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.
