Likely
About 40% of wildlife watchers report a Rough Mabuya sighting in Kubah National Park on a given day, based on 28 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 9th most-seen of the 29 reptiles we can rate there. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.
July
In that month about 60% of wildlife watchers report a Rough Mabuya in Kubah National Park on a given day, against under 5% in September and November, the lowest months. That is one of Kubah National Park's driest months, with about 200 mm of rain against 520 mm in January.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Rough Mabuya sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 7 parks where we can rate Rough Mabuya sightings, Kubah National Park ranks 2nd at about 40%, level with the leaders once rounded. The best odds are in Sepilok (Malaysia, about 40%).
GBIF citizen-science records
It is estimated from how often the Rough Mabuya is recorded against all the reptiles logged in Kubah National Park (28 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.
