The common brown water snake (Lycodonomorphus rufulus) is a species of nonvenomous South African snake. This gentle, harmless snake is by far the most common water snake in southern Africa. It can be found from Cape Town in the south, along the wet east coast of South Africa and inland as far as Gauteng, Lesotho, and Zimbabwe. Throughout its range, its natural habitat is water margins, where it shelters under leaves and logs. It emerges at night to hunt frogs and sometimes rodents. It lays up to 10 eggs at the end of summer.

With luck
About 10% of wildlife watchers report a Common Brown Water Snake sighting in Johannesburg on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 14th most-seen of the 15 reptiles we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
November to February
In those months about 10% of wildlife watchers report a Common Brown Water Snake in Johannesburg on a given day, against under 5% in March to October, the lowest months. Those are among Johannesburg's wettest months, with about 110 mm of rain a month against almost none in July.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Common Brown Water Snake sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 3
Of the 3 cities where we can rate Common Brown Water Snake sightings, Johannesburg ranks 3rd at about 10%. The best odds are in Cape Town (South Africa, about 20%) and Durban (South Africa, about 10%).
Same family: Lamprophiidae
The closest relatives of the Common Brown Water Snake that you can see in Johannesburg (family Lamprophiidae, Lamprophiid Snakes) are Brown House Snake (about 20%) and Aurora House Snake (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Common Brown Water Snake is recorded against all the reptiles logged in Johannesburg (5 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
