Hailstorms are more intense than regular rainfall. They are fast-moving and accompanied by falling hailstones, intense wind gusts, and in many cases, lightning. These weather events usually occur in the evening or night after hot daytime conditions. The impact of hail, strong winds, and lightning can directly damage crops—especially cardamom plants, which are widely cultivated in Idukki.
🌧️ Onset of Rainy Season – Pre-Monsoon Warning Signs
During May, before the official arrival of the Southwest Monsoon, changes in weather patterns begin to appear in the Western Ghats. This phenomenon is known as pre-monsoon convective activity, where heat and atmospheric pressure differences cause localised hailstorms and showers.
Rising Temperatures
In Idukki, daytime temperatures currently range between 28°C and 31°C. This heat during the day supports the formation of clouds, and by evening or night, it often results in hailstorms.
Rain & Hail Forecast for Idukki
May 5 to May 8: Heavy hailstorms with lightning and gusty winds.
May 9 to May 11: Scattered hailstorms and localized intense rainfall in certain areas.
Impact on Cardamom Plants
1. Leaf Tear and Scorching
Hailstorms can cause serious physical damage. Hailstones strike with force, tearing cardamom leaves or bruising them, while lightning and wind can scorch them. This affects the plant’s ability to conduct photosynthesis, leading to stunted growth.
2. Waterlogging & Pest Outbreaks
Accumulated rainwater creates a moist environment that attracts insects and supports the growth of fungi. This leads to leaf blight, grey mold, and other plant diseases in cardamom plantations.
3. Drop in Cardamom Yield
With damaged leaves and weakened plants, cardamom pods fail to develop properly. The result is poorly formed, immature pods that affect the market quality and quantity of the crop.
Reduced Yield – Economic Consequences
Cardamom is a primary source of income in Idukki. Hailstorms during a single growing season can cause 30% to 50% yield loss per acre. This has a ripple effect:
Major income reduction for farmers
Difficulty in repaying crop loans
Job loss for seasonal plantation workers
Idukki is entering a weather pattern where hailstorms are becoming more frequent. Taking early precautions is essential for protecting livelihoods and agricultural output. Farmers and residents should stay updated with daily weather alerts and implement safety measures to avoid losses.
