In short
  • Conditions are quiet now, with only light background activity.
  • A minor G1 storm is expected in the current forecast window, with the peak around 2026-07-12.
  • 2026-07-13 and 2026-07-14 look calmer, with no storm level expected.
  • Weather sensitive people may notice mild effects such as tiredness, a heavier head, or sleep changes.

Current situation

Geomagnetic conditions are currently calm, with the K index at 2. This means there is no storm right now, and the background level remains low. For most people, the day should feel steady and uneventful from a space weather point of view.

Even so, the forecast shows a short period of stronger activity ahead. The expected peak reaches Kp 5, which corresponds to a minor G1 geomagnetic storm.

What to expect next

The main disturbance is forecast for 2026-07-12, so the strongest effects are most likely within the current UTC day. This kind of storm is usually modest, but weather sensitive people may still notice mild symptoms such as fatigue, a slight headache, reduced concentration, or restless sleep.

After that, the outlook improves quickly. The forecast for 2026-07-13 drops to Kp 3, which is below storm level, and 2026-07-14 looks even quieter at Kp 2. In other words, the event appears brief, with recovery conditions likely following soon after the peak.

Simple preparation tips

No special precautions are usually needed for a G1 storm, but a calm approach is sensible. Keeping plans flexible for the rest of the day may be helpful if mild discomfort appears, especially for people who are already sensitive to weather or sleep changes.
