Strong G3-level magnetic storm hit the Earth: possible consequences for Cyprus residents

On September 15, 2025, the Earth faced a powerful G3 (Strong) geomagnetic storm, as reported by the U.S. NOAA service. The phenomenon was caused by a stream of high-speed solar wind originating from a large coronal hole on the Sun. Scientists note that the storm turned out stronger than predicted, and its effects are being felt worldwide.

According to experts, geomagnetic disturbances may last for several days, with varying intensity. New surges of activity are expected soon, increasing the risk of disruptions in navigation systems, satellite communications, and power grids.

For Cyprus residents, the consequences will manifest not only in possible technical malfunctions but also in health issues. Doctors warn that during such periods, people with chronic cardiovascular diseases experience worsening conditions, while complaints of fatigue, headaches, and irritability become more frequent. On the island, where a significant portion of the population suffers from hypertension, doctors advise closely monitoring health and avoiding excessive strain.

There is also a likelihood that the storm will affect maritime and aviation navigation. In the ports of Limassol and Larnaca, as well as in the international airports of Larnaca and Paphos, operators have been advised to consider the possibility of temporary GPS and communication system failures. This is especially important during the active tourist season, when tens of thousands of travelers arrive in Cyprus.

Scientists at the University of Cyprus emphasize that strong magnetic disturbances can indirectly affect the island’s energy system, where in September demand traditionally increases due to widespread use of air conditioners.

Cyprus residents are advised to follow official meteorological service announcements, take care of their health, limit the use of unprotected household appliances when possible, and pay attention to the elderly and children, who are most sensitive to geomagnetic fluctuations.
