Munnar in January

October through May gives you the best weather – clear skies, comfortable temperatures, and minimal rain. December and January can actually get cold enough for sweaters, with temperatures dropping to 5°C at night. This is peak season though, so expect crowds and inflated prices. The monsoons from June to September transform the landscape into something otherworldly – everything turns impossibly green and waterfalls appear overnight. But heavy rains make some roads impassable and outdoor activities risky. Here's the sweet spot: visit in October or April for good weather without the December-January crowds. The tea plants look their greenest just after monsoon season ends.
