Weather data comes from WeatherAPI.com and is refreshed once daily, covering temperature, "feels like," humidity, wind speed, and UV index. "Feels like" is WeatherAPI's own computed figure, factoring in humidity and wind to estimate perceived temperature, which can run noticeably higher than the actual air temperature during India's summer and monsoon months.
