Rain months, Mumbai

On IMD normals, most rain falls between June and September, with the southwest monsoon usually setting in during June. A flat shown between November and May has usually had months to dry out and repaint.

Book before you sign, whatever the season. In the dry months a wall that leaked last monsoon usually still reads above the dry reference, but a fully dried seasonal leak can be missed. Ask the seller directly about last monsoon, and consider a re-scan after the first heavy rain if the agreement allows time.
