It occurs when sea surface temperatures in the central and eastern Pacific Ocean are cooler than normal, which in turn affects global weather conditions. For India, La Ni\u00f1a often brings heavier monsoons, leading to above-average rainfall. While this can be beneficial for agriculture, it may also cause flooding in certain regions. Additionally, La Ni\u00f1a tends to lower temperatures across the country, particularly during the winter months. Understanding La Ni\u00f1a is essential for preparing for its varied effects on India&#8217;s climate and economy.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><a
