Aurora Forecast: Aurora Watch

The night the aurora finally reaches your sky, you don't want to hear about it the next morning. Aurora Forecast: Borealis tells you — in plain language — whether it's worth stepping outside tonight, and alerts you the moment the lights are likely overhead and the sky is dark where you are.

If you've ever chased the northern lights, you know the routine: a dozen browser tabs, a "Kp" number that means nothing without a decoder ring, three apps that disagree, and the quiet fear the best show of the year happened while you were inside. Most forecasts hand you raw space-weather data and leave you to guess what it means for where you're standing.

Borealis does the interpreting for you.

IS IT WORTH LOOKING UP TONIGHT?
• One clear "chance overhead" reading for your exact location — not a generic global number
• An honest one-line verdict that accounts for darkness and moonlight, not just Kp
• The numbers that matter, in plain sight: Kp, how far south the oval reaches, darkness, the moon
• A "next best night" hint so you know when it's worth planning around

REAL FORECASTS, NOT RAW NUMBERS
• A 3-day Kp outlook and a live solar-wind snapshot
• Built on live NOAA Space Weather Prediction Center data and the OVATION aurora model
• Unlock the extended hourly probability and 27-day outlook with Pro

GET THE ALERT, NOT THE REGRET (PRO)
• A push the moment the aurora is likely overhead and your sky is dark
• Set your own probability threshold — only get woken up when it's genuinely worth it
• A live preview that shows whether tonight's conditions would alert you

SEE HOW FAR SOUTH THE LIGHTS REACH (PRO)
