What is the overall climate: is it extremely hot or cold, wet or dry, at any time of year, for example?
Summers are warm and wet: nighttime lows in the high teens / low 20s, daytime highs in the high 20s / low 30s. There is supposed to be rain almost every day, in dramatic fashion - clouds close in around 2pm, it rains for half an hour (sometimes famously hail the size of basketballs), and then the skies open for 4pm and a dramatic sunset. In recent years, lots of days have simply rained all day. Winters are generally clear - as in no rain for 4 months - but cold. Nighttime lows are always below 10, and sometimes (like 4 times in 4 years) dip below 0. Daytime highs can touch 20, but don't expect it to be warm - everywhere inside will still be below 10, so you'll need to wear a jacket indoors, or keep the heat on if you're lucky enough to have any. - Jun 2022
Hot dry summers - but surprisingly cool in the shade. Mild winters that generally have cool days and colder nights. November through February, roughly, is the rainy season. - Oct 2019
Sunny all year round. Winters have cold nights but generally mild days. Summers can be hot but not humid. Even during rainy season (November-March), it's not generally humid, as rain often passes quickly. - Apr 2017
Lovely. But the houses really are poorly insulated. So if it's cold outside, it's cold inside, etc. - Sep 2016
summer is in the 70s and is the rainy season. winter ranges from the 50s to 70s and is dry. - Aug 2011
Climate is mild most of the time. Summers are nice with a bit of rain, but it does get kind of cold in the winters and there is no central air so bring your electric heating blankets. - Jul 2010
It is quite possibly the best weather in the world! It does get cold in the winter and in the evenings, and none of the buildings or houses is heated--which takes some getting used to. Otherwise it is sunny, sunny, sunny! And little to no humidity. The weather is one of the best things about Joburg. - Oct 2009
