Alleppey (Alappuzha) in September
Kerala, India
Monsoon rains taper but afternoons stay wet; houseboat canals are full yet humidity peaks
September in Alleppey is the trickle back. Rainfall drops to 350-400mm across 16-18 wet days, mostly first half. Daytime 25-30C, humidity easing toward 80 percent. Southwest monsoon retreats from Kerala around September 25-30 (IMD declares formal withdrawal). Onam celebrations linger through the first week with snake-boat traditions; Aranmula Boat Race on the Pampa (a religious vallam kali, part of the Aranmula Parthasarathy Temple festival) lands on Uthrattadi day during Onam — typically early September (verify exact date via Kerala Tourism keralatourism.org). Houseboat operators (Lakes & Lagoons, Spice Coast Cruises, Soma Houseboats, KTDC) rebuild full schedules from mid-month. Cruise rates climb 20-25 percent versus August lows: AC houseboats ₹10-15k, luxury ₹18-28k, Marari Beach Resort ₹11-16k. Coconut Lagoon CGH Kumarakom holds full Karkidakam-tail Ayurveda packages through the second week. The full clean cruising window opens from October 10-15 onward.
