August weather forecast
Peru

August brings subtle changes to the weather across Peru's diverse regions as the country begins its transition towards spring.

In the coastal region, where cities like Lima and Trujillo are located, August still falls within the winter season. However, average temperatures begin to rise slightly, ranging from 14°C (57.2°F) to 20°C (68°F). The coastal mist, known locally as garúa, continues to be a common occurrence, and rainfall remains scarce.

In the Andean highlands, August is one of the driest months. Cities such as Cusco and Arequipa experience minimal rainfall, with average precipitation levels around 5mm (0.2"). Daytime temperatures typically fluctuate between 10°C (50°F) and 18°C (64.4°F), while nighttime temperatures can fall below freezing, particularly at higher altitudes.

Over in the Amazon rainforest, cities like Iquitos and Puerto Maldonado experience a similar climate to July. Rainfall in August averages around 100mm (3.94"), and temperatures remain consistently high, generally exceeding 30°C (86°F).

Comparing to July, August's weather patterns remain fairly consistent across all three regions. However, looking forward to September, all regions expect a gradual increase in both rainfall and temperatures as Peru moves closer towards the spring season.
