Thermokarst lakes are shallow bodies of freshwater that develop in permafrost regions, and they an essential focus international research. However, research regarding the mechanisms driving temperature fluctuations thermokarst factors influence these changes is limited. We aimed to analyze seasonal variations surface water temperature, clarify historical trends phenological characteristics lake ice, predict future using air2water model. The results indicated comparison with air lake’s showed a certain lag significantly higher values warm season. warming rate average based on data from 1957 2022 was 0.21 °C per decade, notably August (0.42 decade) than other months. Furthermore, ice-covered period steadily decreased by 2.12 d decade. Based Coupled Model Intercomparison Project 6 projections, 2100, temperatures during season projected increase 0.38, 0.46, 2.82 (under scenarios SSP126, SSP245, SSP585), respectively. Compared typical tectonic Qinghai–Tibet Plateau, have ice-free periods, exhibit (0.21 decade). These elucidate response lakes’ ice climate change.
