New Delhi: The maximum temperature in the national capital on Tuesday settled at 37.9 degrees Celsius, a notch above normal, while the weather office has forecast light rain on Wednesday.

The relative humidity in the evening was 54 per cent. It was 80 per cent at 8 am. The minimum temperature was recorded at 30 degrees Celsius, two notches above normal, according to the India Meteorological Department.
