Lima, Peru experiences a unique microclimate influenced by the cold Humboldt Current. During this transitional month, the city begins to emerge from its winter season, characterized by cool temperatures, overcast skies, and high humidity. While rainfall is minimal, dense fog, known locally as “gara,” is common, particularly in the coastal districts.
Understanding the specific climatic conditions prevalent in Lima during this period is crucial for visitors and residents alike. This knowledge allows for appropriate clothing choices and activity planning. The gradual shift towards warmer, sunnier days also marks the beginning of the shoulder tourist season, offering potentially lower prices and fewer crowds compared to the peak summer months. Historically, September’s weather patterns have played a significant role in the city’s agricultural practices and cultural traditions.
