October to March is the best all-round window for Kerala, but every month has a case. Month-by-month weather, crowds, prices, and festivals to pick your dates.
October to March is the best all-round window for Kerala: dry weather on the coast, calm backwaters, and clear views in the hills. Within that range, January and February have the best weather but also the highest prices and the biggest crowds. October and November are the value sweet spot, with post-monsoon greenery and prices still below the December peak. June to September is the monsoon season: the cheapest hotels of the year and the traditional Ayurveda window, but heavy rain can disrupt sightseeing and the sea turns rough.
Kerala has a tropical climate with three broad phases: a pleasant dry season (roughly October to March), a hot summer (April to May), and the southwest monsoon (June to September). Munnar sits at 1,600 meters and runs about 10 to 15 degrees cooler than the coast, which is why the hills are the refuge in April and May while the coast is at its hottest.
The table below uses long-run monthly averages for Thiruvananthapuram (the state capital, on the south coast). Hill-station figures are estimates derived from the altitude differential, roughly 10 to 15 degrees below coast highs.
| Month | Coast highs | Hill nights (est.) | Rainy days | Sunshine/day |
|---|---|---|---|---|
| January | 32C | 5 to 12C | 1 | 9.1 h |
| February | 32C | 6 to 13C | 2 | 9.2 h |
| March | 33C | 10 to 15C | 3 | 8.8 h |
| April | 33C | 13 to 18C | 7 | 8.0 h |
| May | 32C | 14 to 18C | 9 | 7.0 h |
| June | 30C | 15 to 18C | 17 | 5.0 h |
| July | 29C | 15 to 18C | 14 | 5.3 h |
| August | 30C | 15 to 18C | 12 | 5.8 h |
| September | 30C | 15 to 18C | 9 | 6.2 h |
| October | 30C | 12 to 17C | 11 | 6.1 h |
| November | 31C | 8 to 14C | 8 | 6.0 h |
| December | 31C | 5 to 12C | 4 | 7.5 h |
Coast temperature, rainfall, and sunshine figures are monthly averages from weather records for Thiruvananthapuram; actual conditions vary by year and by location within Kerala.
Cool, dry, and festive. Daytime highs on the coast stay around 31 to 32C with the year's lightest humidity, the backwaters are calm and photogenic, and the hills are clear. This is the best window for a first trip, a honeymoon, or the classic coast-backwater-hills circuit. It is also the busiest and most expensive: mid-range hotel listings typically run Rs.3,000 to Rs.15,000 per night in December to February. Book 4 to 6 weeks ahead for December and January, especially around Christmas and New Year, when the Cochin Carnival fills Fort Kochi with processions and street art. January is arguably the single best weather month; February warms slightly but stays excellent. If you are packing for December specifically, our December packing guide covers the 31C beach days and 10C hill nights in one suitcase.
March is the transition: warming up on the coast, still comfortable in the hills, and one of the better-value months, with hotel prices roughly 20 to 30 percent below December. By April, the coast is genuinely hot and humid, with highs around 33C, and beach lounging gets uncomfortable from noon to 4 PM. The hill stations become the refuge: Munnar and Wayanad stay pleasant through the heat. If your dates fall here, plan the hills first and the coast early or late in the day. Book hill stays early for April and May, since domestic summer holidays fill them. Two festivals can make an April or May trip special: Thrissur Pooram (April or May, dates follow the Malayalam calendar), Kerala's most spectacular temple festival, and Vishu in April, the Malayalam New Year. Houseboats still cruise in these months, but insist on full AC hours in writing: on some budget boats, air conditioning runs only at night. See our houseboat price breakdown for what the different boat categories actually cost in 2026.
The southwest monsoon arrives in June and brings the heaviest rain of the year: Thiruvananthapuram averages 17 rainy days in June, with the Western Ghats getting far more. The sea turns rough and stays dangerous for swimming roughly from May to September. Sightseeing slows and houseboat operators cancel trips on heavy-rain days. So why go? Three reasons: prices, greenery, and Ayurveda. Hotel listing ranges drop to their lowest of the year (roughly Rs.1,500 to Rs.5,000 per night for mid-range stays in June to August), the landscape is at its most dramatic, and the cool, humid monsoon air is traditionally the ideal season for Ayurveda treatments, with retreats quieter and better value. The rain eases through August and September, which is when the culture season peaks: the Nehru Trophy Boat Race in August at Alleppey, and Onam, Kerala's grand harvest festival, in August or September.
Post-monsoon Kerala is the state at its most photogenic: waterfalls at full force, backwaters full, and the hills refreshed. October still brings some retreating-monsoon showers (around 11 rainy days in the south), but November is cool, clear, and lush. Hotel ranges sit around Rs.2,000 to Rs.8,000 per night for mid-range stays, well below the December peak, and crowds are thin. See our 7-day DIY honeymoon budget for shoulder-season cost planning.

| You are travelling for | Best months | Why |
|---|---|---|
| Honeymoon | October to February | Cool hills, calm backwaters, comfortable transfers |
| Family with kids | October to February | Dry, safe weather; everything open and easy for all ages |
| First Kerala trip | October to March | Full access to beaches, backwaters, hills, and wildlife |

| Wildlife (Periyar) | October to March | Dry-season animal sightings around the lake improve toward March and April |
June to September, the monsoon months, usually offer the lowest hotel and houseboat rates, followed by April and May on the coast. The shoulder months just before and after the December to February peak give the best weather-to-price balance.
December has excellent weather but is the busiest month. Hotels, houseboats, and year-end dates fill up early, so book 4 to 6 weeks ahead and expect peak-season prices.
Yes. You get lush scenery, the year's lowest prices, and the traditional Ayurveda season. The trade-offs are heavy rain on some days, rough seas, and possible houseboat cancellations during intense downpours.
October to February is the classic honeymoon window: cool hill stations, private houseboat nights, and beach days without the monsoon. October and November give you the best weather-to-price ratio.
November to February, when the water is calm and the sky is clear. The monsoon can be atmospheric and cheaper if you do not mind rain on deck, but confirm the boat's AC hours and cancellation policy first.
Yes. October brings post-monsoon lushness, full waterfalls, and low crowds, with prices still below the December peak. Expect occasional retreating-monsoon showers, especially in the first half of the month.
