Munnar in May
Kerala, India
Tea estates blur under pre-monsoon haze; visibility won't return until post-June
May in Munnar splits cleanly in two. The first fortnight extends April: daytime 22-28C, humidity 75 percent, Eravikulam NP at Rajamala open at full tempo, tea estate walks workable till noon. Hotel rates at year-low ahead of the monsoon (luxury ₹5-9k, mid-bracket ₹3-5k, homestays ₹1,500-2,500). By the third week, southwest monsoon advance squalls start hitting Kerala — Munnar at 1600m receives the first of the season's 4,000-6,000mm annual rainfall, typically as 1-2 hour afternoon downpours. Visibility from Top Station (32km) and Lockhart Gap viewline collapses to under 200m on rainy afternoons. Mattupetty Dam pedal-boat operations suspend on heavy days. Eravikulam NP suspends visits when trail conditions become unsafe — check eravikulam.kerala.gov.in same-day. Tea Museum at the Nallathanni estate stays open 9am-4pm. The Kochi-Munnar 130km NH85 drive becomes landslide-watch country from May 22 onward — KSEB reports clearance daily but afternoon arrivals risk being held at Adimali for 1-3 hours. Lock the first 10 days, gamble or skip the last fortnight.
