Swakopmun (German for "Mouth of the Swakop") is a city on the Atlantic coast of northwestern Namibia, 280 km (175 miles) west of Windhoek, Namibia's capital. It is the capital of the Erongo administrative district. As a seaside resort, the weather is cooler here in December to January (Namibia's summer months) so the territorial administration moves to Swakopmund for these months. Swakopmund's population as of 2007 is approximately 28,552.
