Sources, method and limits

How these numbers are made (what the highs, lows and rain days mean, the sources and the model cell used for Ribeirão Pires) is explained once on the Ribeirão Pires year overview and on the Sources, method and limits page.

São Bernardo do Campo and Santo André lie in the same rainfall cell, so their rainfall figures are identical to these; temperatures differ because they come from smaller 0.1° cells.
