How the year runs in Munnar — the southwest monsoon, the frost mornings on the high estates, the school-holiday peaks — month by month.
Pick a month
The current month is selected to start.
January
Peak frost season: cold, clear mornings and full viewpoints. Book ahead, start early, and expect weekend gridlock in town.
Weather
Cool, dry and clear. Frost on high-estate mornings — Chenduvarai touched −1°C in January 2023.
Prices
high
Crowds
busy
These are patterns from past years, not a forecast. The Eravikulam closure window is announced each year by the Forest Department. The Neelakurinji's 12-year mass bloom last covered the hills in 2018 and is next expected in 2030.

The year at a glance
January
Peak frost season: cold, clear mornings and full viewpoints. Book ahead, start early, and expect weekend gridlock in town.
February
Good dry walking weather. Eravikulam National Park was closed for tahr calving through February in 2026 — check the year's dates before planning around it.
March
Fine weather between the peaks. In 2026 Eravikulam stayed closed through March and reopened on 1 April — the window is announced each year.
April
Summer holidays begin and the crowds return. Eravikulam reopened on 1 April in 2026, so the park queue joins the town traffic.
May
The other peak, driven by school holidays. By late May the roads can already feel monsoonal.
June
The quietest, cheapest, greenest month — if you accept rain most days and the road risk that comes with it. Check the daily district rain alerts.

July
For mist-lovers on a budget. Landslides on the access roads are a real possibility — read the collector's advisories before travelling.
August
Onam (Thiruvonam falls on 26 August in 2026) lifts Kerala's own travel. August is also the month of Munnar's worst disasters — the 2018 floods cut the town off, and the Pettimudi landslide came on 6 August 2020 — so take rain warnings seriously.
September
The tail of the monsoon — still wet, steadily improving, and quiet.
October
The hills at their greenest as the rain clears out. A good-value shoulder month.
November
One of the best all-round months: still green from the rains, clear enough for the viewpoints, before the December rush.
December
The frost season begins and the crowds come with it — local papers report the season's low temperature as good news. Book early and expect weekend gridlock in town.
October
Post-monsoon: fresh green hills, occasional rain, the air washed clear.
