The climate of Portoviejo
Located in the South American country of Ecuador, Portoviejo experiences a tropical wet and dry climate, also referred to as savanna, as per the Köppen climate classification (Aw). This classification wholly depends upon a sharp contrast witnessed between the wet and dry seasons.
Throughout the year, Portoviejo undergoes subtle but significant variations in weather parameters such as temperature, humidity, and rainfall. Monthly average high temperatures tend to hover around 28.4°C (83.1°F) and 29.8°C (85.6°F), while lows float between 19.6°C (67.3°F) and 22.4°C (72.3°F). This consolidated data indicates quite a consistent and scorched climatic condition, with the highest mean temperatures occurring around April and May at 29.8°C (85.6°F).
Relative humidity percentages remain fairly high throughout the twelve months, reflecting the tropical climate. These percentages range from 69% to 84%, with February marked as the most humid month. Rainfall demonstrates a more distinct yearly pattern, with totals dropping to a minimal 6mm (0.24") in July and August and peaking typically at 132mm (5.2") in January.

One may witness a clear transformation between a wetter, overcast period of the year and the drier, sunnier months, dictated by the tropical savanna climate.
