The southwest monsoon has arrived over Kerala eight days earlier than its usual onset of June 1, marking its earliest appearance in 16 years. This early onset, last seen in 2009, has triggered heavy rains across Kerala, Karnataka, Tamil Nadu, and Telangana, with alerts for extremely heavy showers on May 25–26. The India Meteorological Department forecasts above-normal rainfall this season, offering a major boost to India’s agrarian economy and timely sowing of Kharif crops. With neutral El Niño conditions, experts remain optimistic. The four-month monsoon season contributes over 75% of India's annual rainfall, vital for millions of farmers. (PC: News18)

Delhi is witnessing stark temperature variations across different neighborhoods due to the Urban Heat Island (UHI) effect. Densely populated and concretized areas such as Palam have recorded temperatures 2–3°C higher than greener, less developed zones like Ridge or Lodhi Garden. While Safdarjung showed 40°C, Palam reached nearly 43°C. This localized heating is caused by limited green cover, heat-trapping buildings, and high energy use, particularly air conditioning. Experts warn that these micro-climates are often excluded from official temperature data, masking the real extent of urban heat experienced by residents across the capital. (PC: ANI)

On May 21, 2025, Delhi and the National Capital Region (NCR) were struck by a sudden dust storm accompanied by rain and hail, bringing temporary relief from extreme heat but causing widespread disruption.

On May 21, 2025, Delhi experienced a severe dust storm followed by heavy rain and hail, leading to significant disruptions. Between 7:45 pm and 8:45 pm, at least 10 flights were diverted—primarily to Jaipur and one to Mumbai—and over 50 flights were delayed due to wind shear and intense rainfall. Wind speeds peaked at 74 km/h around 8 pm, causing temperatures in Palam to plummet from 37°C to 23°C within an hour. The India Meteorological Department attributed the sudden weather change to a cyclonic circulation over Haryana, embedded in an east-west trough from Punjab to Bangladesh, with moisture from both the Arabian Sea and Bay of Bengal.

NASA has issued an alert after a powerful X2.7-class solar flare erupted from sunspot AR4087 on May 14, 2025. The flare has already caused radio blackouts across Europe, Asia, and the Middle East. Accompanied by a coronal mass ejection (CME), the solar storm is expected to hit Earth, potentially disrupting GPS systems, satellite operations, and even causing power outages. As the Sun nears its solar maximum in the 11-year cycle, NASA warns of more such intense events. Global authorities are closely monitoring the situation and advising precautionary measures to minimize technological disruptions. (PC: Business Standard)
