With luck
About 10% of wildlife watchers report a Marbled sand frog sighting in Kruger National Park on a given day, based on 21 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 17th most-seen of the 28 amphibians 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 April
In those months about 10% of wildlife watchers report a Marbled sand frog in Kruger National Park on a given day, against under 5% in May to October, the lowest months. Those are among Kruger National Park's wettest months, with about 70 mm of rain a month against almost none in August.
Between 6 and 9 pm
Across all the parks we cover, that three-hour window holds the most Marbled sand frog sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is most active around dawn and dusk.
Only Kruger National Park, in our data
Kruger National Park is the only park on Wallace's Line with enough records to rate Marbled sand 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 Marbled sand frog is recorded against all the amphibians logged in Kruger National Park (21 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.
