This guide describes Ludhiana's historical climate, not a live 15-day forecast. Monthly averages help compare seasons but cannot predict an individual day. Forecast uncertainty generally increases with lead time and depends on the location and weather variable. See the current seven-day forecast for upcoming weather.

67% of Ludhiana's 811 mm falls between June and September, so during those four months a 15-day view is useful for spotting when the next wet spell is due, not for how much rain falls on a given day. The dry half of the year is not completely dry here: 25 rain days and 217 mm between November and April, enough that a two-week view is still worth checking for rain outside the monsoon.
How much a fortnight can tell you in Ludhiana
The wet season builds here rather than breaking. July carries about 6.7 times the rain of May - a real increase, but a gradual one - so a fortnight's view is genuinely about how much and when, not simply whether the season has started.
The other thing worth knowing before reading a two-week forecast here is how far the year swings: 32.2°C between the hottest monthly average maximum and the coldest average minimum. The fastest change is into April, when the average daily maximum moves 7.2°C in a single month - and a forecast crossing that point is doing more work than one in a settled month.
The two turning points in the year
The biggest turn in Ludhiana's year is the monsoon. Over 34 years the first sustained rain arrives around 30 June, and between 17 June and 13 July in half of years. If you are looking at a 15-day forecast in late June, that is the real question you are asking.
The other turn is heat: May averages a daily maximum of 38.7°C, and that falls by 5.1°C once the monsoon is established.
