Read the numbers correctly
Climate, not a promise.
These patterns help compare months. They cannot tell you the weather on a specific day of your trip.
Sources, method and limitsHow these numbers are made (what the highs, lows and rain days mean, the sources and the model cell used for Shahrīār) is explained once on the Shahrīār year overview and on the Sources, method and limits page.
Karaj, Moḩammad Shahr and Shahre Jadide Andisheh lie in the same rainfall cell, so their rainfall figures are identical to these; temperatures differ because they come from smaller 0.1° cells.
