Aurora Forecast Tools & Websites: The 10 Best Resources Reviewed

Government space weather agencies produce the original data and forecasts that every other aurora tool depends on. Knowing these sources directly — rather than through third-party aggregators — gives you access to the most authoritative information, often before it appears in apps and websites that relay it.

1. NOAA Space Weather Prediction Center (swpc.noaa.gov) — Essential

Rating: The gold standard. SWPC is the official U.S. government operational space weather forecasting agency. For aurora watchers, three products are most relevant: the 3-day geomagnetic forecast (updated 4x daily, shows predicted KP by 3-hour window), the 30-minute Ovation Prime aurora oval map (updated every 30 minutes from real-time DSCOVR data), and the real-time ACE/DSCOVR solar wind display showing Bz, speed, and density with running charts. The interface is functional but not designed for casual users — it prioritizes data completeness over presentation. Highly recommended for enthusiasts who want primary-source data without intermediaries. Free, no registration required. Alerts and warnings can be subscribed to by email at no cost.

2. Veðurstofa Íslands / vedur.is (vedur.is/weather/forecasts/aurora) — Iceland Essential

Rating: Best regional tool in the world for Iceland-based aurora watching. The Icelandic Meteorological Office's aurora forecast page is unique because it combines geomagnetic activity prediction (0–9 scale) with cloud cover forecast in a single visual grid showing the next 3 days hour by hour. Each cell shows both the expected aurora activity level AND whether skies are predicted to be clear, partly cloudy, or overcast. This is exactly the combination needed for practical viewing decisions. The cloud cover data draws on high-resolution local weather models optimized for Iceland's complex terrain. For anyone visiting Iceland, this page should be bookmarked immediately upon arrival. All content is available in English.

3. UK Met Office / AuroraWatch UK (aurorawatch.lancs.ac.uk) — UK Essential

Rating: The best UK-specific aurora alert service. AuroraWatch UK, operated by Lancaster University with Met Office collaboration, monitors geomagnetic activity at UK observatories and issues color-coded alerts: Green (no significant activity), Yellow (minor activity possible), Amber (aurora likely from northern Scotland), Red (aurora likely across the UK). The alert emails and API are free and reliable — the notification system is faster than many commercial apps for UK-relevant events. Combine AuroraWatch UK alerts with the Met Office hourly cloud cover forecast for a complete UK aurora planning system.

Several independent websites have built comprehensive aurora and space weather dashboards by aggregating government data with their own visualization, alert systems, and community features. These are the best single-stop resources for aurora enthusiasts who want more than an app's simplified probability score.

4. SpaceWeatherLive (spaceweatherlive.com) — Best All-in-One Dashboard

Rating: The most comprehensive aurora forecasting website available to the public. Belgian-operated and maintained with exceptional attention to detail, SpaceWeatherLive presents real-time solar wind parameters (Bz, speed, density, pressure), a live KP gauge, the current aurora oval, magnetometer readings from stations across the auroral zone, active NOAA alerts, and a solar activity summary — all on a well-organized dashboard that loads quickly on mobile. Their magnetometer page is particularly useful: it shows real-time H-component readings from stations across Scandinavia, Iceland, Canada, and Alaska in a single view, allowing you to see exactly which geographic regions have active aurora happening right now. The SpaceWeatherLive app (iOS and Android) replicates most of the website's functionality and sends reliable push notifications. The free tier is excellent; their premium subscription adds enhanced data views and archive access.

5. Spaceweather.com — Best for CME Event Coverage

Rating: The most-read space weather news and information site, updated daily by professional science writer Tony Phillips. Where SpaceWeatherLive excels at real-time data dashboards, Spaceweather.com excels at explaining what is happening: why today's solar wind conditions developed, which active regions on the sun are Earth-directed, and what observers around the world are reporting seeing. During major CME events, Spaceweather.com posts photo submissions from aurora watchers worldwide within hours of a display, providing real-world confirmation of what forecast models predicted. The "NOAA Forecasts" sidebar links directly to SWPC products. Subscribe to the free daily email newsletter for a curated summary of the day's space weather conditions.

6. Soft Serve News / SolarHam (solarham.net) — Best for Solar Monitoring

Rating: A one-person-operated site maintained by a dedicated amateur space weather enthusiast that has become an essential resource for experienced aurora watchers. SolarHam's front page aggregates real-time data that would otherwise require visiting 5–6 different government websites: the latest ACE/DSCOVR solar wind plots, the current NOAA aurora oval, active region sunspot maps, the latest SOHO coronagraph imagery (for spotting CMEs leaving the sun), and a live X-ray flux chart. Less polished than SpaceWeatherLive but extremely content-dense. Particularly useful for tracking CME development from eruption to Earth arrival in real time.

Borealis — our own app, built for exactly this (iOS, launching soon): We are building Borealis to fold everything this page covers into one screen — a Smart Aurora Probability Score computed from NOAA's live feeds for your exact location, alert thresholds you set yourself, a live aurora map, and a feed of confirmed sightings from other hunters. It is not on the App Store yet, so it does not appear in the numbered rankings below. See the full feature list and get notified at launch.

Mobile aurora apps are essential for practical viewing because they deliver push notifications — the mechanism that alerts you while you are asleep or away from your computer that aurora conditions have become favorable. Here are the top apps with detailed assessments of their strengths and limitations.

7. My Aurora Forecast & Alerts (iOS & Android) — Best Overall App

Rating: The most widely used aurora app worldwide, with consistently high app store ratings above 4.5 stars. Uses your GPS location to calculate a location-specific aurora probability and KP value, then delivers push notifications when activity crosses your chosen threshold. The free version provides core notifications and basic data. The paid Pro version (typically $2–4 USD) adds the aurora oval visualization, real-time solar wind charts, magnetometer data, and a cloud cover layer. The notification system is reliable and fast — typically within 5–10 minutes of a threshold crossing. The main limitation of the free version is limited data depth; for enthusiasts wanting to understand the underlying conditions, the Pro upgrade is worthwhile.

8. Aurora Alerts — Northern Lights (iOS) — Best for Notification Customization

Rating: Strong iOS-focused alternative with the most customizable notification system of any aurora app. Allows notifications based on KP threshold, aurora probability percentage for your location, and optionally suppresses alerts when cloud cover is forecast to exceed a set percentage — a genuinely useful feature that reduces wasted alerts on cloudy nights. The cloud cover integration uses Open-Meteo or similar weather APIs at your device location. Interface is clean and fast. The data depth is slightly less than My Aurora Forecast Pro but the notification intelligence is superior for users who want fewer, more actionable alerts.

9. Northern Eye Aurora Forecast (iOS) — Best in Scandinavia and Iceland

Rating: Popular in Nordic countries and Iceland for its regional tuning and clean Scandinavian design aesthetic. Provides aurora probability on a 1–9 scale calibrated for your specific latitude (so a "6" means the same thing for a user in Tromsø as for a user in Edinburgh — the scale accounts for the different baselines). Includes a cloud cover overlay using local Scandinavian weather model data (leveraging met.no data in Norway and FMI data in Finland). Historical aurora data for your location allows comparison with current conditions. Particularly well-regarded among users in northern Norway and Finland.

Beyond the global tools, several regional forecast services offer localized data that global apps cannot match. Here are the most useful regional resources by geographic area.

10. Finnish Meteorological Institute Aurora Service (en.ilmatieteenlaitos.fi) — Best for Finnish Lapland

Rating: The FMI operates the MIRACLE scientific monitoring network across Finnish Lapland — one of the world's most extensive auroral observing networks. Their public aurora service includes a real-time aurora activity indicator, cloud cover forecast for key viewing locations in Lapland, and live imagery from all-sky cameras at stations including Sodankylä, Nurmijärvi, and Kevo. The magnetometer data from these stations confirms real-world aurora occurrence independent of forecast models. Particularly useful for self-organizing aurora trips in Finland — Rovaniemi, Saariselkä, and Kakslauttanen aurora tourism operators all reference FMI data. All content available in English.

Norwegian Space Agency All-Sky Cameras (northern.no/en/arctic-light) — Best for Northern Norway Visual Confirmation

Rating: A network of all-sky cameras positioned across northern Norway — including Tromsø, Alta, and Andøya — streaming live imagery. Unlike forecast models, all-sky cameras provide visual confirmation that aurora is actually occurring at a specific location right now. During active events, watching the Tromsø all-sky camera show rapidly brightening aurora is one of the most reliable confirmation signals that conditions are excellent. The Northern Lights Centre website provides a user-friendly interface for viewing multiple cameras simultaneously. Free access; no registration required.

AuroraMax (aurora.ualberta.ca) — Best for Canada

Rating: Operated by the University of Alberta and the Canadian Space Agency, AuroraMax is a live all-sky camera at Yellowknife, Northwest Territories, broadcasting high-quality aurora footage from one of the world's prime aurora locations. The website provides live streaming (weather permitting) plus an archive of imagery by date and time. For North American aurora watchers, AuroraMax provides the same real-world visual confirmation function as the Tromsø cameras do for European observers — if AuroraMax is showing aurora, the auroral oval is active over North America. Live streams are particularly valuable during major storm events.

No single aurora tool is sufficient on its own. The most effective aurora watchers use a hierarchy of tools matched to their planning stage — from trip planning weeks out to real-time monitoring on an active night. Here is a practical workflow that uses the tools reviewed above together.

Trip planning (weeks to months ahead):

• NOAA 27-day space weather outlook — to identify elevated activity windows aligned with your trip
• Our aurora season guide — for month-by-month statistics and equinox effect timing
• Vedur.is (for Iceland trips) or yr.no (for Scandinavian trips) — to evaluate historical cloud cover patterns for your destination

Daily monitoring (1–3 days before and during your trip):

• NOAA SWPC 3-day geomagnetic forecast — check twice daily for the KP prediction and narrative discussion
• SpaceWeatherLive front page — for the current solar wind trend and any active NOAA alerts
• Spaceweather.com daily update — for expert interpretation of what is driving current conditions

Same-evening decision (afternoon before going out):

• Vedur.is or yr.no cloud cover — hourly cloud forecast for your viewing location
• SpaceWeatherLive current Bz chart — is Bz currently negative and trending more negative?
• NOAA Ovation model — is the oval approaching or covering your latitude?
• Aurora app notification — is your location-specific probability elevated?

Real-time monitoring (once outside):

• SpaceWeatherLive app — live Bz and KP updates every few minutes
• Northern.no or AuroraMax all-sky cameras — visual confirmation aurora is occurring at key reference stations
• SpaceWeatherLive magnetometer map — see which geographic areas are showing active aurora from ground-truth sensors

Building this workflow takes 30 minutes of initial setup — bookmarking the right pages, installing the right app with alerts configured — and then becomes routine. Experienced aurora chasers run this workflow almost unconsciously during aurora season. See our Aurora Watch page and Aurora Alerts page for integrated monitoring across all these sources in one place.
