🌀
Jakarta itself isn't directly hit by tropical cyclones
Being close to the equator on the north side of Java, Jakarta is not affected by tropical cyclones the way parts of southern Java can be. Storms instead form well to the south near the Cocos and Christmas Islands, most often from December to mid-April.
