Windhoek weather in March

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.

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.
