Visibility, however, usually improves quickly within a few hours after sunrise when the mist dissipates. Fig 3 – Hourly variation of rainfall for each month (1981-2010). The inter-monsoon months (April, May, October and November) are transition periods between the monsoons and show lighter and more variable winds. Relative humidity shows a fairly uniform pattern throughout the year and does not vary much from month to month (Fig 7). About 17% of these are temperature instruments. Wind Its daily variation is more marked, varying from more than 90% in the morning just before sunrise and falling to around 60% in the mid-afternoon on days when there is no rain.
