The cape rain frog or giant rain frog (Breviceps gibbosus) is a species of frog in the family Brevicipitidae. Adults grow up to 45 mm in length. It was the first African frog species to be scientifically described by Carl Linnaeus in 1758, under the name Rana gibbosa. It is the most common and largest of rain frogs. The name "rain frog" that is applied to the genus refers to a belief that these frogs bring rain.
The species is endemic to South Africa, where it occurs in the far southwestern Cape, in Cape Town and northwards as far as Citrusdal. In this area it inhabits Mediterranean-type shrubby vegetation, known as fynbos, renosterveld, pastureland on farms, rural gardens, and even urban areas. It seems to adapt well to suburban gardens, but like most frog species it is vulnerable to herbicide poisons and domestic pets.
Breviceps gibbosus is part of the family Brevicipitidae. All species in this family of frog are considered terrestrial breeders by laying and burrowing eggs. The cape rain frog exhibits a rounded shape, with short arms. There are sexual dimorphisms between sexes, the females are larger in size compared to the males. Cape... Wikipedia →

With luck
About 10% of wildlife watchers report a Giant Rain Frog sighting in Table Mountain National Park on a given day, based on 147 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 7th most-seen of the 18 amphibians we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
June
In that month about 20% of wildlife watchers report a Giant Rain Frog in Table Mountain National Park on a given day, against under 5% in December and January, the lowest months. That is one of Table Mountain National Park's wettest months, with about 110 mm of rain against 15 mm in February.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Giant Rain Frog sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Table Mountain National Park, in our data
Table Mountain National Park is the only park on Wallace's Line with enough records to rate Giant Rain Frog sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Giant Rain Frog is recorded against all the amphibians logged in Table Mountain National Park (147 verified sightings from 2019 to 2026), 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.
