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 São José dos Pinhais) is explained once on the São José dos Pinhais year overview and on the Sources, method and limits page.

Curitiba and Pinhais lie in the same rainfall cell, so their rainfall figures are identical to these; temperatures differ because they come from smaller 0.1° cells.
