Ant Nuptial Flight Predictor

Will they fly today?

Every ant colony waits for the perfect day - then fills the sky with winged queens on their nuptial flight. Ant keepers wait for the same day. This app tells you when it's coming.

THE ANT FLIGHT INDEX Instead of a meaningless percentage, every day gets a clear rating - No-fly, Quiet, Watchful, Promising or Prime - based on how today's weather compares with years of historical days at your latitude and time of year. Prime means the top ~10% of days in your season: drop everything and get outside.

HONEST ODDS "About 1 in 7 days like this see a reported flight." Calibrated against thousands of real sightings - never a made-up probability.

HOUR BY HOUR Flight confidence for the next 24 hours, the best three-hour window to go looking, and the week ahead at a glance.

WHY THIS FORECAST? Full transparency: see exactly how temperature, wind, humidity, cloud, rain and pressure moved today's rating - straight from the model, no hand-waving.

POWERED BY ANT KEEPERS The forecast is a machine-learning model trained on 10,000+ real flight reports from users worldwide. Report a sighting (or "I looked - no flights") and you make it smarter for everyone.
