Windhoek weather in May

May opens Namibia's dry season, which runs through to October, and the forum rates May and June as the quiet, high-value end of it: the rains have stopped, game viewing in Etosha improves as animals concentrate on waterholes, and the crowds have not arrived. Windhoek runs near 24°C by day with essentially no rain — under one wet day in the month — beneath blue, cloudless skies. The catch is the mornings: an average low near 11°C, and campers report 2°C at dawn. Regulars pack warm jackets, gloves, socks and hats for early starts, and that is not over-preparation.

Forum posters describe November in Namibia as building toward stuffy, hot nights, with daytime heat intensified by generally dry air and little cloud cover to offer relief - posters name October and November as feeling like the hottest months of the year for exactly that reason. One visitor's November 2017 trip reported a genuinely dry heat throughout, with no rain at all aside from a sandstorm and heavy wind near Swakopmund. Posters consistently recommend a sun hat as essential and suggest a light sweater for early mornings, while noting evenings otherwise don't require much beyond typical warm-weather clothing. Posters generally rate November as hot but manageable for visiting Windhoek, with the dry heat easier to handle than a humid equivalent.
