        At the beginning of November 2025, Earth is expected to experience a series of geomagnetic disturbances. Forecasts from NOAA, ESA SWE, and SpaceWeather indicate increased solar activity from November 3 to 7, with possible moderate to strong storms at levels G1-G2. Below is what scientists predict about magnetic storms, their potential effects on well-being, and recommendations on how to ease discomfort during this period.
Geomagnetic storm forecast
According to models from NOAA, NASA SDO, and ESA SWE, several waves of geomagnetic fluctuations are possible at the start of November.
- November 3-4: moderate activity (Kp index 4)
 - November 5: likely peak up to G2, a short-term strong storm
 - November 6-7: decreasing activity, but residual disturbances possible
 
These levels are considered moderate, but they can still be noticeable for individuals with weather-sensitive conditions and electronic systems.
What a magnetic storm is
A geomagnetic storm occurs when a stream of charged particles from the Sun collides with Earth's magnetic field.
The intensity of such events is measured on the K-index scale (0-9):
- K-index 4-5 is a moderate storm (G1 level), which may cause mild discomfort
 - K-index 6-7 are strong storms (G2-G3), possible short-term disruptions in power grids and navigation
 
Impact on technology and communication
During geomagnetic disturbances, voltage changes in the ionosphere can affect:
- Satellite systems and GPS navigation
 - Radio communication
 - Power grids
 
For a G2-level storm, no serious consequences are expected, but temporary disruptions in communication or navigation are possible.
How storms affect people
Even moderate fluctuations in the magnetic field can influence well-being. The most common symptoms include:
- Headache
 - Dizziness
 - High or low blood pressure
 - Fatigue and drowsiness
 - Irritability and reduced concentration
 
Who is at risk
Geomagnetic fluctuations affect people differently. The most vulnerable groups include:
- Those with cardiovascular diseases
 - People with hypertension
 - The elderly
 - Weather-sensitive and meteorologically dependent individuals
 - Pregnant women
 - Patients with chronic neurological or endocrine conditions
 
On such days, they may experience headaches, increased fatigue, blood pressure fluctuations, insomnia, and reduced concentration.
How to minimize the effects of a storm
Doctors recommend the following during periods of increased activity:
- Sleep at least 7-8 hours
 - Drink plenty of water, avoid coffee, alcohol, and energy drinks
 - reduce stress and overexertion
 - Eat light meals: vegetables, fruits, fish, and minimize salt and fat
 - Take walks in the fresh air, but avoid overexertion
 - Follow medication schedules if you have chronic conditions
 - Monitor space weather forecasts, as solar activity can change daily
 
Although the storms from November 3 to 7 do not pose a global threat, moderate geomagnetic activity may still affect well-being and technology. Be attentive to your health, follow simple guidelines, and stay informed about forecasts. This will help you get through the period without unnecessary stress.
