Kolukkumalai Tea Estate is known for being one of the highest tea plantations in the world. Given its elevation and the subtropical highland climate of the region, the best time to visit is typically from September to May. During these months, the weather is pleasantly cool and is conducive for sightseeing and tea plantation tours. Visitors can enjoy the panoramic views and breathe in the aroma of fresh tea without the hindrance of heavy rainfall that can occur during the monsoon season from June to August. The temperature ranges between 10°C and 25°C, which is ideal for strolling among the tea bushes and experiencing the verdant surroundings at their most vibrant.
The peak tourist season is from December to February when Munnar experiences a cool, sometimes chilly climate. This is the perfect time for tea enthusiasts and photographers to capture the sprawling emerald-green plantations against the backdrop of clear blue skies. Early mornings at Kolukkumalai are magical, with chances to witness a spectacular sunrise above the rolling hills. Although the mornings can be misty, the mist usually clears by noon, offering a clear view of the stunning landscape. It's vital to bring along warm clothing if you plan a visit during these colder months, as temperatures can dip quite low, especially in the early morning and evenings.
