How accurate are the weather forecasts available to the public in India

In this study, forecasts from three weather websites (Real Time Weather System, Weather Underground and Accuweather) are evaluated for six Indian regions. Average statistics for all the Indian locations are calculated for the standard weather parameters - maximum and minimum temperature, wind speed, wind direction, pressure and rainfall. The correlation between predictions and synoptic observations is similar for all three forecasters. Bias magnitude is also similar for all three websites. Regional analysis demonstrates that Accuweather predicts maximum temperature best in the Central, Northwest and West regions, and Weather Underground performs well for the East and West regions. Real Time Weather System produces consistently accurate minimum temperature forecasts for all regions.
