Hyderabad woke up to thick fog on the morning of January 1, 2026. Visibility was poor in many parts of the city until around 9 a.m. The India Meteorological Department (IMD) explained that moisture had gathered close to the ground, causing the fog. Naga Ratna, Head of IMD Hyderabad, told The Hindu, “There was some accumulation of moisture at the lower levels of the atmosphere, within about 0.9 km to 1 km above the ground. This resulted in fog formation at the surface level.” She said such dense fog is unlikely to continue. “However, mild fog or mist could occur over the next day depending on prevailing conditions. The situation is not favourable for dense fog to continue, but there could be instances of mist or light fog,” she added.
