What to expectMetro through the year

Metro changes little through the year. Average daily highs stay between 29 and 31 °C, so no month stands out as a season in the way it would further from the equator.

Counted across a normal year, 365 days a year reach 25 °C, 159 of them reach 30 °C. The warmest reading in the 1991–2020 record is 38 °C, in October.

Rain is strongly seasonal. December averages 273 mm against 66 mm in September — 4.1 times as much. Planning around the dry months matters more here than planning around temperature.
