Magnetic storms in April 2025: when to expect
Kyiv • UNN
In April 2025, magnetic storms of varying intensity are expected, especially in the second half of the month. The most powerful storms are predicted for April 12, 25 and 26.
In April, we are expecting a series of geomagnetic bursts of varying intensity throughout almost the entire month. Storms of medium and high intensity will occur mainly in the second half of April. This is reported by UNN.
The level of magnetic storms is estimated by the Kp-index (index of geomagnetic activity):
- 0–3: no disturbances;
- 4–5: weak storm;
- 6–7: moderate storm;
- 8–9: strong storm.
According to preliminary forecasts, storms are expected in April:
- Weak magnetic storms: 5, 6, 30 April;
- Medium intensity storms: 1, 2, 9, 10, 15, 16, 17 April;
- Powerful magnetic storms: 12, 25, 26 April.
Very strong disturbances can be felt even by healthy people. Moderate ones will mainly affect weather-dependent people. And weak ones are unlikely to cause much discomfort.
During geomagnetic fluctuations, a person may experience a deterioration in mood and well-being, irritability, anxiety, an increase or decrease in blood pressure, headache, drowsiness or insomnia, rapid heartbeat, etc.
How to reduce the impact of magnetic storms on health
For weather-dependent people, it is important to regularly monitor forecasts of geomagnetic activity. This will allow you to prepare in advance and reduce the negative impact on your well-being.
On these days, it is advisable to reduce physical and psychological stress, ensure a good night's sleep, maintain water balance in the body (drink at least 2 liters of water a day), and avoid fatty foods and alcohol. Add walks to your daily routine or at least ventilate the room more often: fresh air will help improve your well-being.
The most powerful storms in history
The Carrington Event (1859) - the sun released an unprecedented amount of magnetized plasma, causing an extremely powerful storm. It destroyed telegraph lines around the world, causing fires. During the peak, the storm reached a maximum level of G5 (Kp=9).
The "Fatima Storm" of 1938 - massive emissions on the sun lasted more than 9 hours in a row. Transatlantic radio communications were completely interrupted for 12 hours. The aurora borealis was so strong that people around the world mistook it for fire and firefighters.
1989 - in Canada, due to a magnetic storm, an entire Canadian province was left without electricity for 9 hours. Even over Simferopol at this time, the Northern Lights were observed. Satellites lost contact with Earth, and the aurora borealis was seen even in Mexico.
