Traveller notes on Mindelo in September
Other months in Mindelo
Forum posters describe April across Cape Verde as normally lovely and sunny, with visitors pretty much guaranteed non-stop sunshine and daily sunshine hours running toward their February-through-June peak. Posters are consistent, though, that it still runs a bit windy this time of year, with the trade winds behind Cape Verde's generally pleasant year-round temperatures also capable of making evenings chilly enough to want a light jacket or coat. Given limited destination-specific detail for Mindelo on Sao Vicente specifically, this note leans on that broader archipelago-wide pattern, which should apply reasonably well across the islands: sunny, dry, and windy, with April sitting comfortably within Cape Verde's generally mild, low-rainfall stretch of the year.
