It is pleasant to walk with an umbrella in the drizzle. And the storms of April through November particularly those of October and November which account for half the annual rainfall can serve up first rate son-et-lumiere shows with rolling bass drums of thunder and lightning that forks across the sky and backlights clouds. Note that October and November can also if rarely, bring rain for days at a time or very rarely a cyclone. Clouds are another delight in puducherry. They pile over the sea in cumulous baroque billows and fronts with fine cirrus detailing. And they often produce remarkable sunsets at both the western and eastern horizons. It is a good idea to keep your head up except in March and April when the skies are remorselessly clear and more bleached than blue. The Bay of Bengal is affected by the weather as well as by the moon. The sea has many aspects, most of the grey cast. In the mid-morning, waves carry tons of blinding molten light to extinction on the rocky shore.
