The summer solstice has begun in the Southern Hemisphere, marking the official start of the warmest season in Argentina. According to the Argentine News Agency and the Naval Hydrography Service, this astronomical event occurred on December 21st at 15:03 local time. The summer solstice is when the Sun reaches its maximum southern declination relative to the equator. On this day, the Earth's axis reaches its maximum tilt of approximately 23.5 degrees, resulting in the longest day and shortest night of the year. This period also sees the highest incidence of solar radiation. The National Meteorological Service forecasts a summer cycle with temperatures exceeding historical averages. Consequently, authorities have issued warnings about an increased risk of heatwaves, particularly in the northern and central parts of the country. Health officials recommend taking extra precautions: stay hydrated, use sunscreen and appropriate clothing, avoid outdoor activities during peak sun hours, and pay special attention to children, the elderly, and individuals with chronic illnesses. Following the solstice, the period of daylight will gradually decrease until the next autumnal equinox on March 20, 2026.
