Everything below is collected in one spot so you do not have to cross-check Shiraz climate: monthly averages by hand. The gap between Jan and Jul is 24.6 C here: 4.3 C against 28.9 C. Precipitation peaks in Jan (1.72 mm/day) and bottoms out in Sep (0.02 mm/day), so a 86.0x difference between the two. Taken together that is roughly 275 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 Shiraz climate table shows
Values are multi-decadal climatological averages for the 29.6103, 52.5311 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 1.72 mm/day in a month?
Rain is recorded as a daily mean, so 1.72 mm/day is roughly 52 mm across a 30-day month.
