Best time to visit Kerala, month by month
By Ganesh ·
When to visit Kerala: the seasons, a month-by-month guide, the best time for backwaters, beaches, hills, wildlife and Ayurveda, festivals like Onam and Thrissur Pooram, and whether the monsoon is worth it.
The short answer: the best time to visit Kerala is September to March, when the weather is warm and dry, the beaches are calm and the hills are clear, with December and January the busiest. The monsoon (June to August) is the best time for Ayurveda, lush green hills, waterfalls and low prices, though beaches are rough. April and May are hot on the coast but pleasant in Munnar, Wayanad and Vagamon. Festivals tip the balance: Onam in August–September, Thrissur Pooram in April–May and Theyyam in North Kerala from November to May.
Weather and festival dates vary from year to year. Check before you go.

Month by month
- January: peak season; perfect for Alleppey houseboats, Varkala and Kovalam, Periyar and the hills. Book early.
- February: still dry and pleasant; Attukal Pongala in Thiruvananthapuram usually falls in February or March. Eravikulam National Park in Munnar usually closes for a few weeks around now for the tahr calving season.
- March: warming up; good value at the end of the season; temple festival season begins.
- April: hot on the coast; Vishu festival; head for Munnar, Wayanad or Vagamon. Thrissur Pooram usually falls in April or May.
- May: peak domestic summer travel to the hills; pre-monsoon showers late in the month.
- June: the monsoon usually arrives in the first week. Dramatic, green, cheap, and wet.
- July: heaviest rain; the traditional month (Karkidakam) for Ayurvedic treatments.
- August: rain easing; the Nehru Trophy snake-boat race on Punnamada Lake, usually on the second Saturday; Onam may start late in the month.
- September: Onam (in most years), green hills and fewer tourists; good shoulder month.
- October: the north-east monsoon brings afternoon showers; landscapes are at their greenest.
- November: season starts; Theyyam rituals begin in North Kerala (Kannur and Kasaragod); Sabarimala pilgrimage season brings crowds in the south.
- December: peak season, Christmas and New Year, the Cochin Carnival in Fort Kochi; prices at their highest.
Best time by experience
- Backwaters and houseboats: November to February; monsoon cruises are atmospheric and cheaper.
- Beaches (Varkala, Kovalam, Marari): October to March. Avoid swimming in the monsoon.
- Hill stations (Munnar, Wayanad, Vagamon, Thekkady): September to May; April–May for escaping the plains' heat.
- Wildlife (Periyar, Wayanad, Eravikulam): October to April, when animals gather near water.
- Ayurveda: June to August is traditionally preferred.
- Festivals: Onam (August–September), Thrissur Pooram (April–May), Theyyam (November–May), boat races (July–September).
- Neelakurinji bloom: once every 12 years in Munnar, the last was 2018, so the next is expected around 2030.
Monsoon in Kerala: worth it?
Yes, if you plan for it. Hotels and houseboats can be 30–50% cheaper, waterfalls like Athirappilly are at full force and the hills are spectacular. The downsides: heavy rain can disrupt sightseeing, hill roads sometimes close after landslides, and the sea is closed for swimming. Keep a flexible plan and a buffer day.
Practical tips
- Pack light cotton for the coast and a jacket for the hills, whatever the month.
- Carry an umbrella in every season.
- Book December–January stays and houseboats 6–8 weeks ahead.
- Indian searches for Kerala trips peak around May and November; plan before those months.
- Build a classic loop (Kochi, Munnar, Thekkady, Alleppey, Varkala) in Sancharees to see drive times and share the plan.
