Within Kerala itself, the highest rainfall occurs in the Western Ghats (e.g., Neriamangalam, Peerumedu, Walakkad), where orographic lift of the Southwest Monsoon yields 3,000–5,000 mm annually. Kerala's state average is ~3,000 mm; the Ghats' windward slopes catch the moisture before it crosses into the Deccan rain shadow.
