<p>Water levels can modify the tidal amplitudes and generate the overtides, which are very crucial in tide-dominated shallow coastal environments for practical applications. High-frequency, long-period water level observations are limited in creek channels due to shallow depth restrictions. This study attempts to investigate the tidal behavior and its impact on a shallow creek environment utilizing a network of buoy-based observations. The amplification of diurnal constituents by 0.92% and the damping of semi-diurnal constituents by 22.46% were identified at the riverine upstream as compared to coastal environment. The shallow water constituents were generated in the creek due to nonlinear interaction with the primary constituents, which in turn was amplified by 11.94% at the upstream, and a similar behavior was noticed in the long period constituents by 9.6%. Average water temperature recorded by buoy 1 was 30.24&#xa0;°C and at buoy 2 was 30.48&#xa0;°C during August 2023, similarly, 29.23 ℃ and 29.05 ℃ during October 2023. High tide reduces the water temperature by 2.17 ℃ in August 2023 and increases by 0.55 ℃ in October 2023 at the upstream. Semi-diurnal tide has a strong impact on water temperature, with the existence of thermal stratification in August 2023 and a well-mixed water column in October 2023. Study also signifies that near-surface air temperature and relative humidity were slightly influenced by the tidal action. The tide regulates the near-surface latent heat flux, dominated by the semi-diurnal band; however, the sensible heat flux has a minor influence on tides. The findings clearly signify the impact and role of tides in a shallow coastal environment utilizing high-frequency observations.</p>
