Best Time to Visit Kerala: Month-by-Month Weather and Seasons

Short answer: The best time to visit Kerala is December to February, when the coast is dry at 28–32°C, Munnar is a cool 15–22°C and the backwaters are at their clearest. October–November and March are good shoulder months with fewer visitors. The south-west monsoon runs roughly June to September; it is wet, green and cheap, and the traditional season for Ayurveda. April and May are hot and humid on the coast but still pleasant in the hills.

Why does Kerala have two monsoons?

Kerala is the first part of mainland India that the south-west monsoon reaches. The India Meteorological Department treats the onset over Kerala as the official start of India’s rainy season, with a normal date of 1 June; in 2026 the IMD forecast arrival around 4 June (Onmanorama, 2 Jun 2026). The heaviest rain falls in June and July, with a lull in August and a tail into September. The Western Ghats catch most of it, which is why Munnar and Wayanad are so green.

The second, lesser-known monsoon is the north-east monsoon, which brings afternoon and evening thunderstorms from roughly mid-October to the end of November. It is far lighter than the summer monsoon and rarely wrecks a day, but it is why October mornings are often brilliant and October afternoons can be wet. By the first week of December the sky usually settles into the dry season that lasts until the pre-monsoon showers of April and May.

The practical consequence for visitors is that Kerala has a clear best window (December to February), two decent shoulder periods, and a monsoon that is a different kind of trip rather than a bad one.

Kerala month by month

Temperatures are typical ranges from our own trips and standard climate averages; Kerala’s humidity makes 32°C feel hotter than the same reading in Rajasthan. Where to go in each winter month across the rest of India is in our guides to India in January, February and March.

Is December to February really the best time to visit Kerala?

For a first visit, yes. The backwaters are calm and clear, Munnar has crisp mornings and the beach towns of Varkala and Kovalam have their full season of cafés and yoga. It is also when Europe and North America are coldest, so flights are busiest; book international legs early. Hotels in Munnar and premium houseboats sell out for 20 December to 5 January, and our Kerala Honeymoon Special runs about 25 per cent higher in that window than in the 1 November–19 December and 6 January–14 March off-season bands. See Kerala in December for the Christmas specifics.

The one thing December–February cannot give you is Eravikulam National Park in February or March. The park near Munnar closes for the Nilgiri tahr calving season every year and reopened on 1 April 2026 (Outlook Traveller, 1 Apr 2026). If seeing the tahr matters, come in December–January or April–May. Our Munnar travel guide has the alternatives.

What is the shoulder season like?

October–November is our favourite period for value. The land is still green from the monsoon, waterfalls such as Athirappilly are at their fullest, and hotel rates have not yet climbed to December levels; our Kerala trip cost guide shows how prices move through the year. The cost is the north-east monsoon’s afternoon storms, so we schedule drives and sightseeing before lunch and keep afternoons for the pool, a massage or a covered verandah. By late November the storms fade.

March is the other shoulder. It is dry and warming on the coast (mid-30s by the end of the month) but perfect in the hills. It is also when the Kathakali and temple festival calendar is busy across central Kerala, and when Holi, barely celebrated in Kerala, empties North India of visitors heading south.

Should you visit Kerala in the monsoon?

It depends on what you want. Three groups do well in June–September:

• Ayurveda guests. Traditional practitioners hold that the cool, moist monsoon air opens the pores and makes treatment more effective. Resorts run their most serious programmes now, at lower rates. See our Ayurveda retreat guide.
• Photographers and slow travellers. The rain comes in bursts, not all day. Between showers the light on the paddies and tea gardens is remarkable.
• Festival travellers. The snake-boat racing season starts with Champakulam in July and peaks with the Nehru Trophy on Punnamada Lake, Alleppey, held on Saturday 22 August in 2026 (Alappuzha district administration). Onam follows in late August or September; Thiruvonam is listed for 13 September 2027 (Astrosage; confirm nearer the time).

Who should avoid it: anyone whose trip depends on Periyar boat rides and Munnar viewpoints, both of which can be cloud-bound for days, and anyone nervous about hill roads, where landslips occasionally close the Munnar and Wayanad routes for hours. Houseboats keep running, but the backwaters are brown and high rather than mirror-calm. For a route that works in every season, see our 5, 7 and 10-day Kerala itinerary.

What about April and May?

The coast is hot (33–36°C) and humid, and pre-monsoon thunderstorms arrive by late afternoon. It is still workable if you split the day: beach or backwater before 10:00, hills or air-conditioning in the afternoon. Munnar, Thekkady and Wayanad are at their best in April, with Eravikulam reopened and the tahr with young. Thrissur Pooram, Kerala’s largest temple festival with caparisoned elephants and a percussion ensemble of hundreds, is listed for 17 April 2027 (Drik Panchang; check locally before booking). Indian school holidays make the hills busy in May.

Which festivals should you plan around?

How does the season change the itinerary?

In the dry season we run the full loop: Kochi, Munnar, Thekkady, a houseboat night and a beach finish, with time on the water at every stop. Our backwaters guide and Alleppey houseboat guide cover the water side; the 20 best Kerala experiences covers everything else.

In the monsoon we shorten hill transfers, swap a houseboat for a homestay with a covered canoe trip, and build the trip around an Ayurveda resort. In April–May we put the hills in the middle of the day and the coast at dawn and dusk. Whichever month you choose, a light rain shell, a sun hat and quick-dry clothing belong in your bag; our India packing list has the rest.

Frequently asked questions

What is the best month to visit Kerala?

January. The south-west and north-east monsoons are both over, days are dry at 23–32°C on the coast and 8–20°C in Munnar, and the Christmas–New Year price surge has passed. December and February are nearly as good. If you prefer fewer people and lower rates, November and early March are the next-best choices.

When is the monsoon in Kerala?

The south-west monsoon normally arrives about 1 June and lasts until September, with June and July the wettest. In 2026 the IMD forecast onset around 4 June. A lighter north-east monsoon brings afternoon thunderstorms from mid-October to late November. Kerala receives rain from both, which is why it stays green all year.

Is Kerala worth visiting in the monsoon?

Yes, if you want Ayurveda, low prices and green landscapes rather than beaches and boat rides. Rain falls in bursts, houseboats keep running and resorts run their most serious treatment programmes. Avoid it if your trip hinges on Periyar wildlife boats, Munnar viewpoints or long hill drives, which cloud and landslips can disrupt.

Is Kerala too hot in April and May?

The coast is hot and humid at 33–36°C with afternoon thunderstorms, so plan beach and backwater time before 10:00. Munnar, Thekkady and Wayanad stay pleasant at 14–27°C, and Eravikulam National Park reopens in April after its calving closure. Thrissur Pooram, listed for 17 April 2027, is the big festival of the period.

When should you book for Christmas and New Year in Kerala?

Three to four months ahead for houseboats and Munnar resorts, and earlier for popular Ayurveda retreats. The 20 December to 5 January window carries surcharges of roughly 25 per cent on our packages and more at some hotels, and premium houseboats sell out. Flights into Kochi from Europe and the Gulf are also at their fullest.

When does Eravikulam National Park close?

Every year in February and March for the Nilgiri tahr calving season; it reopened on 1 April 2026 (Outlook Traveller). If the tahr matter to you, visit Munnar between April and January. During the closure, tea estates, Top Station, Mattupetty and the Kolukkumalai estate are the Munnar alternatives.
