Why this forecast?
Aurora Zone
Higher Aurora Zone = better aurora visibility. Your location's Aurora Zone determines how often auroras appear overhead.
Status Levels:
Kp index
Kp measures global magnetic disturbance. Higher Kp = stronger auroras visible at lower latitudes.
Status Levels:
Cloud Cover Impact
Clear skies are essential for aurora viewing. Clouds block your view of the northern lights. The percentage shows cloud coverage (0-25% = clear, 85%+ = overcast).
Status Levels:
Moonlight
Bright moonlight can wash out faint auroras. New moon provides the darkest skies for optimal viewing.
Status Levels:
Darkness
Darker skies are essential for aurora viewing. The sun must be below the horizon for auroras to be visible.
Status Levels:

Aurora is Rare in Sliema — But Not Impossible
Aurora Borealis Viewing in Sliema
Coastal resort town with no northern lights.
Sliema sits at 35.8° magnetic latitude, which means aurora typically becomes visible when the Kp index reaches 9+. Aurora sightings in Sliema require stronger geomagnetic storms (Kp 9+), which occur a few times per year. When storms do hit, the best viewing window is 10 PM to 2 AM local time under clear, dark skies.
Cloud cover is the most common reason people miss aurora even during strong storms. AuroraMe combines the Kp index with real-time cloud forecasts, moon phase, and darkness data to give you a single visibility status — so you know whether it's worth going outside tonight.

Based on its magnetic latitude of <strong>35.8°</strong>, aurora viewing in Sliema is <strong>extremely rare (visible only during exceptional geomagnetic storms)</strong>. We are currently near solar maximum (2024-2025), so expect higher-than-average activity.
Best viewing season: September to March, with peak activity during equinoxes (September and March).
What Kp index do I need to see aurora in Sliema?
For Sliema, you need a minimum Kp index of <strong>8.0</strong> for aurora to be visible. This threshold is calculated based on the city's magnetic latitude (35.8°).
Higher Kp values produce brighter, more active displays:
- Kp 8.0-9.0: Faint aurora visible in dark skies
- Kp 9.0-10.0: Moderate aurora with dancing patterns
- Kp 10.0+: Strong, colorful displays visible even with some light pollution
Current Kp index: 2.3
Where should I look for aurora in Sliema?
Aurora is rarely visible this far south. When it does appear during extreme storms (Kp 7+), look for a faint glow on the northern horizon.
For best results, seek locations with minimal light pollution and unobstructed views of the sky. From Sliema, aurora typically remains closer to the horizon, so elevated viewing locations help.
