The Indian Climate shows simulation data, not measured data, for the selected coordinate (lat: 12°49'60"N, lon: 79°45'0"E | Olaiyur) and is not compared to measured data of a weather station. Wind and temperature data are calculated with the average altitude therefore, the temperatures for mountains and coasts can be different from the data at the exact coorinate which you have selected.
