Best 8 Aurora Forecasts in 2026: Find Dark-Sky Windows

Introduction

My Aurora Forecast & Alerts is the best overall aurora forecast app for most people. This roundup compares iPhone and Android apps for alerts, visibility estimates, space-weather data, maps, webcams, cloud cover, and local viewing conditions. Keep in mind that accuracy depends on your location, darkness, clouds, and changing solar activity.

Quick comparison table

1. My Aurora Forecast & Alerts

Best for: Most iPhone users who want a balanced aurora forecast.

Current KP readings, visibility estimates, global aurora maps, solar-wind data, and forecasts from the next hour to several weeks give this app plenty of useful information. Push alerts and live aurora webcams also help you decide whether conditions are worth checking outside.

Its main strength is balance. You get quick guidance for tonight as well as longer-range planning, without having to rely on a single space-weather measurement.

2. Hello Aurora:Alerts & Forecast

Best for: iPhone users who want customizable alerts and local context.

Set viewing locations, check real-time aurora forecasts, review solar-activity metrics, and include cloud cover when deciding whether to head outside. Community sightings offer a useful second opinion when the forecast points to activity but the situation is still uncertain.

The best part is the flexible notification control. Pro features add longer-range forecasts, peak viewing hours, and more alert options for people who want fewer, more relevant notifications.

3. Hello Aurora: Aurora Forecast

Best for: Android users who want forecasts plus community reports.

Frequently updated predictions, aurora and substorm alerts, a live map, custom locations, and photos from other observers make this a practical Android option. Solar-activity explanations also help newcomers understand what KP levels and substorms mean for visibility.

Its main advantage is the mix of a readable forecast and live community sightings. You get both model-based information and reports from people watching the sky.

4. Aurora Forecast.

Best for: iPhone users who want detailed maps and technical data.

This app brings together NOAA OVATION maps, probability maps, solar-wind and geomagnetic readings, multi-day KP charts, and a 3D globe. Community sightings and webcams provide useful reality checks when forecast models point to possible activity.

Its standout feature is the range of visual tools. Instead of reducing conditions to one score, it lets you inspect the maps, readings, and geographic outlook for yourself.

5. Aurora Forecast & Alerts

Best for: iPhone users who want forecast windows and configurable KP alerts.

Interactive aurora maps sit alongside solar-wind measurements, 30-minute geomagnetic forecasts, and three-day and 27-day space-weather outlooks. SWPC alerts provide another source for significant solar-weather events and can be useful during stronger activity.

Its main strength is the range of forecast windows. Immediate geomagnetic information helps with tonight’s decision, while the longer outlooks support travel and general planning.

6. Aurora Alerts - Northern Light

Best for: Android users who want visibility probabilities tied to their location.

Short-term, three-day, and 27-day forecasts are combined with KP readings, solar-wind data, and local weather information. Configurable alerts let you wait for a notification instead of opening the app repeatedly to check for changes.

The key feature is its location-based visibility probability. It turns space-weather information into a more practical question: are conditions near your saved location worth viewing?

7. Aurora Forecast by Aurora Labs

Best for: Android users who want aurora and weather information on one dashboard.

The color-coded layout combines viewing conditions, live alerts, community sightings, and solar-wind measurements. Its 24-hour, three-day, and 27-day KP forecasts cover both immediate decisions and longer trip planning.

The dashboard is the main draw. Color coding makes several changing conditions easier to scan, especially when you want a quick answer instead of a technical explanation.

8. AuroraMe: Northern Lights App

Best for: Android users who want a visibility score based on local sky conditions.

AuroraMe combines space weather with cloud cover, moon data, hourly forecasts, saved locations, and a 3D globe. Storm and viewing alerts cover both major solar events and everyday chances to see the lights.

Its main strength is the aurora visibility score. By combining several inputs into a simpler local recommendation, it can be easier for beginners than reading raw solar-wind and geomagnetic charts.

How we picked these apps

We compared how quickly each app updates its forecast, how clearly it presents short-term signals, and whether it offers useful planning tools beyond tonight. Short-term predictions are generally more helpful when deciding when to look, while three-day and 27-day outlooks work better as planning guides.

We checked for practical indicators such as:

• KP index and geomagnetic activity
• Solar-wind measurements
• Cloud cover and moonlight
• Visibility probabilities or local viewing scores
• Hourly, three-day, and 27-day forecasts

Alert controls also mattered. The better apps let you save a location, adjust notification thresholds, or choose between general aurora alerts and specific events such as substorms or high KP readings.

Additional tools helped set the apps apart. We considered aurora maps, NOAA data, 3D globes, live webcams, community sightings, weather dashboards, and explanations of space-weather terms. These features can make a forecast easier to understand, especially if you are not familiar with solar-wind speed or geomagnetic activity.

Finally, we kept iOS and Android availability separate. A technically strong app is not much use if you cannot install it on your phone. None of these apps can guarantee a sighting. Clouds, light pollution, darkness, timing, and your exact location still matter more than a promising number on the screen.

Frequently asked questions

What does an aurora forecast app measure?

Most apps combine the KP index, solar-wind conditions, and geomagnetic activity to estimate where aurora may be visible. Some also add cloud cover, moonlight, local weather, and a visibility probability or score to show whether the sky near you is actually suitable.

How far ahead can I trust an aurora forecast?

Short-term alerts and forecasts covering the next few hours are usually the most useful when deciding whether to go outside. Three-day forecasts can help with general planning, while 27-day outlooks show possible patterns rather than dependable viewing times. Solar activity can change quickly.

Does a high KP index guarantee visible northern lights?

No. A high KP value does not guarantee a sighting from your location. You still need darkness, clear skies, limited light pollution, suitable timing, and a location far enough north for the activity. Moonlight can also make faint aurora harder to see.

Apps that provide visibility scores are often easier for beginners because they combine several conditions into one recommendation. Experienced viewers may prefer raw KP, solar-wind, and geomagnetic data so they can judge the situation themselves.

Two aurora forecast apps may disagree because they update at different times, use different models, cover different locations, or trigger alerts at different thresholds. Save your actual viewing location, allow location access only when needed, and always check cloud cover before traveling.

Some features may require a paid upgrade, including longer-range forecasts, peak viewing hours, advanced alert settings, or additional local details.

The verdict

My Aurora Forecast & Alerts is the strongest overall pick because it balances visibility estimates, KP data, maps, alerts, solar-wind details, longer forecasts, and webcams. Aurora Forecast. is the runner-up for iPhone users who prefer detailed maps, NOAA data, and technical readings. On Android, Aurora Forecast by Aurora Labs stands out for its clear aurora and weather dashboard. Check short-term conditions and cloud cover before relying on any forecast.
