Geomagnetic storms today

On Sunday, July 13, 2025, a kIndex reading of 4 indicates a moderate level of geomagnetic activity, typically characterized by minor disturbances in the Earth's magnetic field. This level is often associated with a mix of quiet and unsettled conditions, where auroras may be visible at higher latitudes, but most areas will experience minimal effects. For weather-sensitive individuals, a kIndex of 4 may contribute to mild fluctuations in conditions that can influence well-being. People who are particularly sensitive to changes in atmospheric pressure, electromagnetic fields, or solar activity might experience slight increases in headaches, irritability, fatigue, or mood swings. While these effects are generally mild, individuals with certain health conditions, such as migraines or anxiety disorders, may be more attuned to the subtle changes in their environment. Overall, while a kIndex of 4 suggests increased geomagnetic activity, the associated impacts on daily life and health are typically minimal for most people. It's advisable for sensitive individuals to remain aware of their personal responses to such fluctuations.
