Chennai feels like “Where the monsoon arrives in October, the beach runs thirteen kilometres, and Tamil matters more than Hindi”, while Lausanneis “Olympic capital on a steep lakeside hill, built around EPFL and the world's steepest metro”. Climate is a real differentiator: Chennai — tropical wet and dry — hot and humid year-round, with the main rains in the october-to-december north-east monsoon. Lausanne — lake-moderated and noticeably milder than the swiss plateau — mild enough for the lavaux vineyards, though winter fog often sits on the upper districts while ouchy stays in sun.
