Everything below is collected in one spot so you do not have to cross-check Guayaquil climate: monthly averages by hand. The gap between Mar and Dec is 1.4 C here: 26.5 C against 27.9 C. Precipitation peaks in Feb (7.60 mm/day) and bottoms out in Sep (0.08 mm/day), so a 95.0x difference between the two. Taken together that is roughly 781 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 Guayaquil climate table shows
Values are multi-decadal climatological averages for the -2.1962, -79.8862 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 Guayaquil get the same every year?
Close to it. Averaging decades smooths variation, so treat these as typical rather than guaranteed.
