Northern lights in Tofte
Tofte needs an active night: from about Kp 3.3 the aurora appears low over the north horizon, and it rises higher as activity grows. Since 1995 storms of Kp 4.7 or more reached this place during darkness on 890 nights.

Only in photos, if at all
- Solar activity Enough for a camera: Kp 2.7 expected, 1.7 needed for photos, 3.3 for the eye.
- Sky Mostly clear (1% cloud).
- Darkness Dark from 19:33 to 06:33.
What to do: Point a phone in night mode north (3–10 s exposure). A red or green glow often shows on the screen before you can see it.

How far ahead can the northern lights be forecast?
- Minutes to an hour: satellites 1.5 million km away measure the solar wind before it reaches Earth. This is the surest warning — the “Right now” box uses it.
- 1–3 days: when the Sun throws out a cloud of particles, it takes one to three days to arrive. NOAA's 3-hourly forecast covers these nights; the timing can still be off by a few hours.
- 4–27 days: the Sun turns once every 27 days, and regions that disturbed Earth's field last time often do it again. NOAA's 27-day outlook gives this rough trend — new eruptions are not in it yet.

Cloud layers and weather
Low cloud blocks the aurora completely. Thin high cloud often still lets a bright aurora shine through, so a sky with only high cloud is worth a look.

The Kp scale in plain words
Kp is a 0–9 score for how strongly the Earth's magnetic field is being shaken by the solar wind. The higher it goes, the further from the poles the northern lights reach. Kp 0–2 is a quiet night; Kp 5 and above is a geomagnetic storm.
- Kp 0–2 Quiet camera in Tofte Only under the auroral oval: northern Norway, Swedish and Finnish Lapland, Iceland, Alaska, northern Canada.
- Kp 3 Unsettled next 24 h eye in Tofte Bright in the Arctic; low on the horizon in central Scandinavia and southern Iceland.
- Kp 4 Active Overhead in the Arctic; low in the north from southern Norway, Sweden, Finland and northern Scotland.
- Kp 5 Minor storm (G1) Scotland, southern Scandinavia, the Baltic states, the northern US states and southern Canada.
- Kp 6 Moderate storm (G2) Northern England, Denmark, northern Germany and Poland, the US Midwest — often clearer in photos than to the eye.
- Kp 7 Strong storm (G3) Most of the UK, the Netherlands, Germany, Poland, Czechia; red glow in photos from France and the northern Alps.
- Kp 8 Severe storm (G4) Central Europe to the eye; red sky in photos from northern Italy, Spain, the Balkans and Turkey's Black Sea coast.
- Kp 9 Extreme storm (G5) Seen across Europe and the US; in photos as far south as the Mediterranean, Turkey and North Africa (May 2024).
Light pollution
Dark rural sky. Little artificial light. Faint displays are visible once your eyes have adapted.
A noticeably darker area starts about 40 km to the west. Open in OpenStreetMap
Estimate from NASA VIIRS night-light data (sky-glow model within 50 km). Check access and private land before you go.
Hills and mountains
The terrain rises to about 9° above the horizon towards the north. That hides low aurora: here you need about Kp 3.3 instead of Kp 3. A hilltop, shore or open field with a clear view to the north helps.

Darkness through the year
- No full darkness (Sun 12° below the horizon) from 12 May to 31 July — the sky stays too bright for most auroras.
- Next new moon 9 November, next full moon 26 October. The darkest skies are in the week around new moon.

Tofte needs an active night: from about Kp 3.3 the aurora appears low over the north horizon, and it rises higher as activity grows.
Which way should I look for the aurora in Tofte?
Face north (about 358° from true north). At Kp 3.3 the lower edge of the aurora sits roughly 25° above the horizon; stronger activity lifts it higher and further across the sky.
What is the best month to see the aurora in Tofte?
Over 2005–2025, March gave the best odds in Tofte (12% of nights dark, active enough and mostly clear), followed by February (9%).
When is the aurora season in Tofte?
From 12 May to 31 July the sky in Tofte never gets dark enough. Outside that period the aurora can be seen whenever activity and clouds allow.
Is there much light pollution in Tofte?
Little artificial light. Faint displays are visible once your eyes have adapted. A noticeably darker area starts about 40 km to the west.
When was the aurora last possible in Tofte?
Activity last reached storm level (Kp 5 or more) during darkness in Tofte on 10 October 2026 (Kp 7.0) — 890 such nights since 1995. Here the aurora also appears on many quieter nights.
