Everything below is collected in one spot so you do not have to cross-check Madurai climate: monthly averages by hand. The gap between Dec and Apr is 7.0 C here: 23.5 C against 30.5 C. Precipitation peaks in Oct (6.34 mm/day) and bottoms out in Jan (0.28 mm/day), so a 22.6x difference between the two. Taken together that is roughly 955 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. Exact monthly values are in the table; links below cover adjacent locations and years.

What the Madurai climate table shows
Values are multi-decadal climatological averages for the 9.919, 78.11953 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 6.34 mm/day in a month?
Rain is recorded as a daily mean, so 6.34 mm/day is roughly 193 mm across a 30-day month.
