How does the migraine weather calculation work? calculates the migraine forecast for the coming 7 days. This forecast should be interpreted as the weather’s influence on migraine symptoms that already exist. The forecast consists of 5 categories:

  1. Very low (green)
  2. Low (yellow)
  3. Moderate (orange)
  4. High (red)
  5. Very high (purple)

When conditions are very favourable the weather has a positive influence and can alleviate migraine symptoms. When conditions are very unfavourable the weather can significantly aggravate migraine symptoms.

The following parameters can cause a unfavourable score:

  • Decreasing pressure
  • Extreme heat
  • Extreme cold
  • High humidity
  • Bright sunlight
  • Strong increase in wind
  • Thunderstorms
