Travancore & Kuttanad · Western Coastal Strip
Terrain and eco-zones
Tropical monsoon with two wet seasons. The southwest monsoon lands first on this coast in the first week of June and runs to September; the northeast monsoon returns in October and November as evening thunder. Annual rainfall runs roughly 2,500–3,000 mm on the plain and well over 4,000 mm on the Agasthyamalai slope. The lagoon districts are humid year-round and rarely drop below 22 °C at night.

Through the year
| Season | Months | Typical | What it is like |
|---|---|---|---|
| Punja preparation and harvest | October–March | 23–33 °C | The agricultural year that defines Kuttanad. Bunds are repaired from October, the fields are pumped out, sowing follows in November and December, and the harvest runs February to March. The Thanneermukkom shutters stay shut across most of it to keep salt water out of the crop. |
| Summer | March–May | 26–36 °C | Humid and still on the lagoon. Chettikulangara Bharani and the Padayani season fall here, and the backwater is at its lowest and saltiest before the shutters open. |
| Southwest monsoon | June–September | 23–30 °C | Continuous rain, flooded fields and the whole vallam kali calendar — Champakulam in June or July, the Nehru Trophy in August, Aranmula and Payippad at Onam. Boat races exist because this is when there is enough water to row on. |
| Sabarimala season and the northeast monsoon | November–mid-January | 22–32 °C | Mandala pooja runs for 41 days from mid-November, and Makaravilakku falls on 14 January. Pathanamthitta district and every road towards Pamba and Erumeli work to that calendar. |
Best time to visitNovember to March for the backwaters, the coast and the Kuttanad harvest. August if the point is the snake boat races, which means accepting mid-monsoon rain. Aranmula's race falls on Uthrattadhi, the day after Thiruvonam, so it moves with the Malayalam calendar and needs checking against the year.
