India’s southwest monsoon has shown weak progress over western India, especially Maharashtra, amid developing El Niño conditions and a large early-season rainfall deficit. IMD’s latest monsoon outlook, rainfall data and extended-range forecasts point to weak cross-equatorial flow, below-normal rainfall risk, heatwave conditions in parts of Maharashtra, and possible implications for kharif sowing, food inflation, water security and disaster preparedness.

The India Meteorological Department (IMD), in its June 2026 ENSO and Indian Ocean Dipole bulletin, has confirmed that El Niño conditions have emerged over the equatorial Pacific Ocean and are likely to strengthen through the southwest monsoon season. The announcement follows a similar confirmation by the US NOAA and accompanies IMD's revised 2026 monsoon forecast of 90% of the Long Period Average — a "below normal" season. This article explains El Niño, the ENSO cycle, the Niño 3.4 index and the Indian Ocean Dipole, shows how the Walker Circulation links Pacific warming to a weaker Indian monsoon, and assesses what a deficient monsoon means for agriculture, food prices and heatwaves in India.

The Zojila Tunnel, beneath the avalanche-prone Zojila Pass on National Highway-1, achieved its final excavation breakthrough on 9 June 2026 when engineers blasted through the last stretch of rock to link the Kashmir and Ladakh ends. Once operational, this high-altitude tunnel will provide India's first year-round road link between the Kashmir Valley and Ladakh, ending the region's winter isolation. This article explains the project's features, the strategic and defence significance of the route, India's broader Himalayan border-connectivity push, and the engineering and economic dimensions of this landmark.

With the Strait of Hormuz effectively closed and contested amid the 2026 Iran war, energy tankers are increasingly "going dark" — switching off their AIS transponders to cross the chokepoint undetected. Once a tactic of the sanctioned-oil "shadow fleet", dark transits now make up the majority of crossings, raising collision and enforcement risks. This article explains the geography and importance of the Strait of Hormuz, how AIS and the dark/shadow fleet work, the conflict context, India's heavy dependence on the strait for oil, LNG and LPG, India's energy-security response, and the wider issue of maritime chokepoints — all mapped to the UPSC syllabus.

The India Meteorological Department (IMD), in its second-stage long-range forecast on 29 May 2026, lowered its 2026 Southwest Monsoon estimate to 90% of the Long Period Average (LPA), pushing the season into the "below normal" category amid a developing El Niño. This article explains the monsoon mechanism, the meaning of LPA and IMD's rainfall categories, how El Niño (ENSO) and the Indian Ocean Dipole (IOD) shape Indian rainfall, the impact on agriculture and inflation, and why ample reservoirs and foodgrain buffers offer a silver lining.

India and China held the 35th meeting of the Working Mechanism for Consultation and Coordination on India-China Border Affairs (WMCC) in Beijing on 27 May 2026, with both sides describing the talks as "constructive and forward-looking." The two nations discussed delimitation of the Line of Actual Control (LAC), border management, mechanism building and cross-border cooperation, while reaffirming that peace and tranquillity in border areas remain the foundation for gradual normalisation of bilateral relations. This article explains the WMCC framework, the Special Representatives mechanism, the chronology of disengagement after the 2020 Galwan clashes, the historical roots of the boundary dispute, key bilateral agreements (1993, 1996, 2005, 2013), the trans-border rivers issue, and the strategic significance of the upcoming Doval–Wang Yi talks for UPSC aspirants.

Western and Central Europe are in the grip of an extraordinary May heatwave, with the UK and France recording their highest-ever May temperatures and parts of Spain crossing 38°C — temperatures 10 to 15°C above seasonal norms. Driven by a "heat dome" trapping warm air, the event coincides with the rapid emergence of an El Niño phase in the equatorial Pacific, which the India Meteorological Department (IMD) has flagged as a key reason for cutting its 2026 Southwest Monsoon forecast to 90% of the Long Period Average — a "below normal" category. This article explains the science of heat domes, ENSO, Walker Circulation, the Indian Ocean Dipole, climate whiplash, IMD's heatwave criteria, and what a strong El Niño could mean for India's agriculture, inflation, and food security.
