From May 19 to the end of June, astronomers and space weather centers expect a series of magnetic storms of varying intensity. The period falls within a phase of increased solar activity, and 2026 is already emerging as one of the most "stormy" in terms of the number of geomagnetic disturbances over the last decade. Experts warn that such phenomena affect both technological systems and people with increased sensitivity to changes in the geomagnetic environment.
What to expect between May 19 and the end of June
Forecasts for geomagnetic activity are based on observations of solar flares, solar wind, and indices that describe the state of the Earth's magnetosphere. Data indicates that from the second half of May to the end of June, several consecutive episodes of increased activity are possible – from milder disturbances (level G1) to moderate magnetic storms (G2–G3).
Since the beginning of the year, the number of days with geomagnetic events has been growing, and the first months showed more "stormy" days compared to the averages for previous years. This supports the expectation that in 2026 we will observe more frequent and longer periods of an unstable geomagnetic environment.
The specific dates and strength of the storms are subject to constant updates – forecasts are adjusted every few hours according to the actual behavior of the Sun and registered flares. However, the general framework remains: between May 19 and the end of June, the probability of magnetic storms is significantly higher than usual.
Why 2026 is "stormier" than usual
Magnetic storms are directly related to the solar cycle, which lasts approximately 11 years. In the period around the peak of the cycle, the number of sunspots, flares, and coronal mass ejections increases – these are precisely what generate strong streams of charged particles reaching the Earth.
In previous years, a gradual increase in solar activity was observed, and 2025 was already recorded as one of the busiest in terms of the number of magnetic storms within the current cycle. 2026 is expected to continue this trend, with the number of days with geomagnetic disturbances remaining high, even if the peak of activity is gradually beginning to pass.
In practice, this means that the period from May to June 2026 falls into a "window" with an increased risk of frequent, though not always extremely strong, magnetic storms – a factor that must be considered by both infrastructure operators and people with chronic illnesses.
Effect on technology and infrastructure
A magnetic storm is a reaction of the Earth's magnetic field to powerful streams of solar particles. When these streams reach the Earth, they can disrupt the operation of satellites, navigation systems, radio links, and power grids.
During stronger storms (level G3 and above), there is an increased risk of errors in GPS signals, interruptions or degradation of radio communications, disturbances in the operation of satellite systems, and even induced currents in power lines, which in extreme cases can lead to damage to electrical infrastructure. Therefore, network and communication operators monitor space weather forecasts daily and implement protective modes as necessary.
In the daily life of ordinary consumers, the effect is usually felt as short-term disturbances in communications or navigation, but in combination with other factors, it can create difficulties in transport and logistics.
How magnetic storms affect health
The scientific community still lacks a unified position on the exact degree of influence of magnetic storms on the human body, but observations and medical practice show that for some people, there is a connection between geomagnetic disturbances and certain complaints.
Most often, weather-sensitive individuals and those with chronic diseases report:
– headaches and a feeling of heaviness;
– increased fatigue and difficulty concentrating;
– irritability, tension, anxiety;
– sleep disturbances – difficulty falling asleep or restless sleep;
– fluctuations in blood pressure and heart palpitations in people with cardiac problems.
People with hypertension, cardiovascular diseases, diabetes, autonomic disorders, and elderly patients are at higher risk. For them, any additional stress factor – including a change in the geomagnetic environment – can exacerbate pre-existing symptoms.
Practical precautionary measures from May 19 to the end of June
Experts emphasize that magnetic storms are not a cause for panic, but for reasonable planning. This is especially important for people with chronic diseases and those who know they react more sensitively to changes in the weather.
What weather-sensitive people and those with chronic diseases can do:
– Ensure regular and sufficient sleep, trying to maintain a constant bedtime and wake-up routine.
– Reduce intense physical exertion on days with expected stronger storms – replace them with walks and light exercises.
– Drink enough water and avoid heavy, fatty, and highly salty foods that place additional strain on the cardiovascular system.
– Monitor your blood pressure if you are prone to hypertension, and do not miss prescribed medications.
– Limit caffeine, alcohol, and nicotine, which can increase heart palpitations and feelings of tension.
Tips for organizing daily life:
– If you feel dizzy or unsteady, postpone long car trips or entrust them to another driver.
– Plan more demanding tasks for days with calmer geomagnetic conditions, if possible.
– Reduce screen time in the evening (phone, computer, TV) so as not to burden the nervous system and to improve sleep quality.
– If you have implanted medical devices, strictly follow the recommendations of your attending physician and do not miss check-ups.
Information as the best defense
Forecasts for solar activity and magnetic storms are updated regularly, and specialized websites and media publish daily and monthly calendars of expected disturbances. People with increased sensitivity can monitor such sources to more carefully plan their schedule between May 19 and the end of June.
Magnetic storms are a natural part of the interaction between the Sun and the Earth. In a year like 2026, when their frequency is higher, the key is awareness, moderation, and care for one's own health. Thus, even people who feel "space weather" more strongly can get through this period more calmly and under control.
