How Our Midge Forecast Works
Our forecast analyses real-time weather data from the Open-Meteo forecast service to predict midge activity across 12 Scottish regions. Data is refreshed hourly so you always have up-to-date predictions for the week ahead.
What We Measure
Five weather factors are scored and weighted based on their influence on midge behaviour:
- Wind speed (heaviest weighting) — midges cannot fly in winds above about 6 mph, making this the single best predictor of midge activity.
- Temperature — midges are most active between 12–20°C. Below 10°C or above 25°C, activity drops sharply.
- Humidity — high humidity (above 70%) creates ideal conditions; dry air suppresses activity.
- Cloud cover — overcast skies favour midges; bright sunshine reduces activity.
- Rainfall — light rain keeps conditions damp and humid, but heavy downpours temporarily suppress midges.
These factors are combined with a seasonal modifier (midges are dormant outside late May–September) and converted into a 1–5 risk scale.
Understanding the Risk Levels
- 1 — Very Low: No precautions needed. Midges unlikely to be noticeable.
- 2 — Low: Minor activity possible at dawn and dusk. Most people won’t be bothered.
- 3 — Moderate: Noticeable midge presence, especially in sheltered spots. Repellent recommended.
- 4 — High: Significant midge activity. Repellent and long sleeves strongly advised.
- 5 — Very High: Severe conditions. Head nets and full precautions essential for comfort outdoors.

Forecast FAQ
How accurate is this midge forecast?
Our forecast is based on the weather conditions known to drive midge activity — wind, temperature, humidity, cloud cover, and rain. It provides a reliable indication of likely midge levels, but local conditions can vary (a sheltered glen may have worse midges than an exposed hillside in the same region). Use the forecast as a planning guide alongside your own observations on the ground.
How often is the data updated?
Weather data is refreshed hourly from the Open-Meteo forecast service. The 7-day forecast updates automatically, so the predictions for later days become more accurate as those days approach.
Why does my region show “Very Low” in winter?
Highland midges are only active from roughly late May to September. Outside this window, the seasonal modifier reduces all scores to 1 (Very Low) regardless of weather conditions, because midges are dormant during the colder months.
Can I use this forecast to plan a trip?
Yes — check the 7-day forecast for your destination before travelling. If you’re flexible on location, compare regions to find lower-risk areas. East coast and island regions typically score lower than the west Highlands. For detailed trip-planning advice around midge season, see our complete midge guide.
