You can see the Northern Lights best in the high-latitude night skies during clear, dark conditions, typically from late autumn to early spring. Here are top-region options and quick tips. Where to see them

• Norway: Tromsø and the Lyngen Alps are famous for frequent aurora displays and accessible infrastructure. Tromsø is a convenient base with many tours that chase auroras, while areas beyond the city offer very dark skies.
• Iceland: The countryside around Reykjavik, as well as more remote spots like Thingvellir or remote low-light valleys, provide strong chances when geomagnetic activity is high.
• Finland (Finnish Lapland): Rovaniemi and especially areas around Abisko-like microclimates in Finnish Lapland offer reliable aurora opportunities with long winter nights.
• Sweden (Swedish Lapland): Abisko is widely highlighted for its favorable weather patterns and clear skies, aided by its rain-shadow location.
• Canada and Alaska (for North American travelers): Yukon, the Northwest Territories, and Alaska’s interior (Fairbanks) sit in strong aurora zones with long, dark nights.

Timing and conditions

• Best months: September–April, with peak viewing often in December–March when nights are longest.
• Weather: Prioritize clear, cold nights. In winter, snow and wind can limit visibility, so consider multi-night plans or guided tours that monitor forecasts.
• Moon phase: A new moon or crescent moon reduces sky brightness and improves visibility of fainter auroras.

Practical tips

• Choose a dark, open location away from artificial lights. Even a short drive from town can make a big difference.
• Dress warmly and bring layers, plus a thermos and snacks if you’ll be waiting for long periods.
• Consider guided aurora tours; guides know local weather patterns, vantage points, and photography tips.
• If you’re flexible, plan around aurora forecasts and be prepared to chase clear skies rather than staying in one fixed spot.
• For photography: use a sturdy tripod, a wide-angle lens, exposure times around 5–20 seconds, ISO 800–3200 depending on light and aurora activity, and manual focus set to infinity.
