Geomagnetic storms today

On Friday, October 31, 2025, the geomagnetic activity level, indicated by a kIndex of 4, is categorized as moderate. This level signifies a range of geomagnetic fluctuations that can occasionally impact Earth’s magnetic field but is generally considered manageable for daily activities. For weather-sensitive individuals, such as those with certain medical conditions or those who are more attuned to environmental changes, a kIndex of 4 might lead to mild disruptions in their comfort levels. Symptoms could include headaches, fatigue, or changes in mood, as these individuals may be more reactive to geomagnetic shifts. While it is not as severe as higher kIndex levels, awareness of geomagnetic activity can help those sensitive to it prepare for potential fluctuations in their well-being. Overall, a moderate kIndex like 4 is unlikely to cause major disruptions but can serve as a reminder for sensitive individuals to stay attuned to their health and adjust their routines as necessary.
