What to expectGuayaquil through the year

Guayaquil changes little through the year. Average daily highs stay between 28 and 29 °C, so no month stands out as a season in the way it would further from the equator.

Rain is strongly seasonal. March averages 375 mm against 52 mm in November — 7.2 times as much. Planning around the dry months matters more here than planning around temperature.
