Can you see the northern lights in Rothesay?
From Rothesay the aurora is seen only during geomagnetic storms (about Kp 5.3 or more), usually as a glow low in the north-north-west. Cameras often pick it up before the eye does. Since 1995 that level (Kp 5.3) was reached during darkness here on 474 nights.

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.

Weather in Rothesay
The aurora only shows through clear skies, so the weather matters as much as the Kp index. Here is the general forecast for Rothesay: temperature, wind and the chance of rain for the coming days.

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 Only under the auroral oval: northern Norway, Swedish and Finnish Lapland, Iceland, Alaska, northern Canada.
- Kp 3 Unsettled next 24 h Bright in the Arctic; low on the horizon in central Scandinavia and southern Iceland.
- Kp 4 Active camera in Rothesay Overhead in the Arctic; low in the north from southern Norway, Sweden, Finland and northern Scotland.
- Kp 5 Minor storm (G1) eye in Rothesay 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 10 km to the east-north-east. 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 3° above the horizon towards the north-north-west. That hides low aurora: here you need about Kp 5.3 instead of Kp 5.3. A hilltop, shore or open field with a clear view to the north-north-west helps.

Which way should I look for the aurora in Rothesay?
Face north-north-west (about 344° from true north). At Kp 5.3 the lower edge of the aurora sits roughly 19° above the horizon; stronger activity lifts it higher and further across the sky.
What is the best month to see the aurora in Rothesay?
Over 2005–2025, September gave the best odds in Rothesay (3% of nights dark, active enough and mostly clear), followed by May (2%).
When is the aurora season in Rothesay?
Rothesay gets dark enough for the aurora all year round, though the long winter nights give the most hours to watch.
Is there much light pollution in Rothesay?
Little artificial light. Faint displays are visible once your eyes have adapted. A noticeably darker area starts about 10 km to the east-north-east.
When was the aurora last possible in Rothesay?
The most recent night in our data when activity reached the level Rothesay needs, during darkness, was 3 July 2026 (Kp 7.0). It has happened on 474 nights since 1995.
