During this month, temperatures average between 26°C (78.8°F) to 31°C (87.8°F), which, while still warm, represents a slight decrease from the peak temperatures of August. The influence of the Atlantic Ocean ensures that coastal cities such as Praia and Mindelo experience the lower end of this temperature range, offering a more moderate climate.

Despite this increase, rainfall events remain sporadic, and many days in September are still sunny and clear, continuing to favor outdoor activities.

As for wind conditions, the Harmattan winds from the Sahara are not present in September. This absence results in clearer skies and lower dust levels, improving visibility across the archipelago, particularly within the interior regions of the islands.

Looking forward to October, the next month, temperatures continue to decrease as autumn progresses. However, the amount of rainfall begins to decline, signaling the end of the wetter season. Consequently, the transition from September to October in Cape Verde is marked by cooling temperatures and a reduction in rainfall, moving back towards the typically dry conditions characteristic of the archipelago.
