One page for Merida climate: monthly averages, sourced from public APIs and refreshed automatically. Expect 23.3 C at the coldest (Jan) and 29.5 C at the warmest (May) — a 6.2 C spread. Expect a wet season rather than rain year-round: Sep brings 6.26 mm/day against 0.63 mm/day in Mar. Taken together that is roughly 1,042 mm of rain a year for the grid cell. Values come from a public open API; a successful result is cached so a later outage never blanks the page. The table underneath carries the per-month breakdown; the related pages cover the same dataset nearby.

What the Merida climate table shows
Values are multi-decadal climatological averages for the 20.967, -89.62318 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
Why do the numbers differ from a weather app?
An app shows one location on one day. These are long-run averages, so they smooth out single hot or cold spells.
How much rain is 6.26 mm/day in a month?
Rain is recorded as a daily mean, so 6.26 mm/day is roughly 190 mm across a 30-day month.
