Northern lights Scotland tonight
Seeing the aurora from Loch Lomond and the Trossachs
Northern lights Scotland tonight? From Loch Lomond and the Trossachs it takes a strong storm. The Met Office says a severe or extreme geomagnetic storm, Kp 8 to 9+, brings the aurora over the UK, and at Kp 6 to 7 it can be faintly visible. Check the live outlook below, then pick a dark spot with a clear view north.

Can you see the northern lights from Loch Lomond?
Yes, but rarely, and only when a strong storm lines up with clear skies. Loch Lomond lies at about 56 degrees north, in the south of Scotland. The British Geological Survey says the further north you are in the UK, the better your chances, so Skye, Caithness and Shetland beat the Trossachs on an ordinary night.
What is Kp? It is a score from 0 to 9 for how disturbed Earth's magnetic field is, worked out every 3 hours from observatories. NOAA says 1 is calm and 5 or more is a geomagnetic storm. Kp 5 is rated G1, Kp 6 is G2 and Kp 7 is G3. The higher the number, the stronger the storm and the further south the lights can be seen.
Which Kp do you need here? No official source gives one number for the Trossachs, so this is our reading of two. The Met Office says it takes a severe or extreme storm, Kp 8 to 9+, to bring the aurora belt over the UK, while at Kp 6 to 7 it can be faintly visible, and the lights are sometimes seen as far south as Scotland if skies are clear. Plan on Kp 6 or more for a first try, expect a faint glow low in the north at that level, and do not expect colour to the eye. A camera shows more than you do: BGS says a faint display may look white or grey to the eye while a long exposure picks up greens, reds and purples.
When is the best time? The strongest magnetic storms tend to happen around the spring and autumn equinoxes, says BGS. VisitScotland gives October to March as the season, with the best window from 9pm to 2am. NOAA announced in October 2024 that the Sun was at solar maximum for Solar Cycle 25, which is why aurora forecasts keep making the news. It gives no end date for the maximum, so do not count on it.
Cloud and the moon decide most nights. The aurora is far above the clouds, but you need cloud-free skies to see it, and a bright full moon washes out a faint display (both BGS). Check the cloud forecast as well as Kp, and look up the moon phase for the night you plan to go.
Aurora outlook for the next three nights
This outlook updates through the day. It is a forecast of storm strength, not a promise of lights: you still need a clear sky to the north.
- TonightKp up to 4.0: unlikely by eye, sometimes caught by a camera on a very dark night.
- Wednesday nightKp up to 3.3: very unlikely.
- Thursday nightKp up to 2.3: very unlikely.

Dark spots with a view north near Loch Lomond
These are places with a road, a car park and an open view, not measured dark-sky sites. We have no sky-darkness readings for any of them. The National Park is not an official Dark Sky Park: VisitScotland lists Galloway Forest Park among Scotland's dark-sky sites and names Loch Lomond & The Trossachs only under other stargazing locations. Face north, keep away from village lights and use a compass app to find north.
| Place | Getting there | Parking | Check first | Map |
|---|---|---|---|---|
| Loch Katrine, Stronachlachar | The B829 from Aberfoyle runs 11 miles to Stronachlachar at the western end of the loch, on a single-track road. Loch Katrine and its steamship has the rest of the loch. | Pay at the parking post. Stronachlachar takes cash only; Trossachs Pier takes cash or card. We found no tariff. | We found no gate or night-time access times. Phone the ticket office on 01877 376315 before an evening trip. | Open in maps |
| Inversnaid | The RSPB reserve at Garrison Farm, FK8 3TU, is reached by the B829 from Aberfoyle: 12 miles (19 km) of single track, then left at the T-junction. Inversnaid on the east shore covers the hamlet. | Not verified for night use. | Single track for 12 miles: allow time, and plan the drive home in the dark. | Open in maps |
| Inveruglas | Inveruglas Visitor Centre, G83 7DW, is on the A82. The An Ceann Mor viewpoint is 126 m from the centre, up 31 steps, with views across the loch to the Arrochar Alps and Ben Lomond. Inveruglas on the west shore has more. | Pay and display machines in the car park, according to the National Park access guide updated in 2019. | That guide gives daytime toilet hours only. Check the car park rules after dark. | Open in maps |
| Rowardennan | The road ends at the east shore of the loch. Forestry and Land Scotland runs the car park, postcode G63 0AR. Rowardennan and Ben Lomond is our guide. | £2 up to 1 hour and £5 all day, by coins, card or RingGo. | Toilets are open Easter to October. Read the signs for overnight rules. | Open in maps |
| Duke's Pass, A821 | The entrance to Three Lochs Forest Drive is on the east side of the A821, about 2 miles north of Aberfoyle, near FK8 3SY. | Not given in the pages we read. | We found no gate or closing times for the forest drive. Check before you drive in after dusk. | Open in maps |
Sky darkness is not measured here. Check a light-pollution map for your exact spot, and tell someone where you are going.
Plan a night out
Check the outlook the afternoon before
Use the live block above, then confirm with the NOAA and Met Office pages listed there. Kp is a forecast, and forecasts change. Expect to be disappointed more often than not, and treat a good night as a bonus.
Check the cloud
You need gaps in the cloud over the northern horizon. Use a cloud forecast for the exact area, and if the hills are in cloud, move. What the weather is like around the loch explains how fast it changes.
Check the moon
A bright full moon washes out a faint aurora. The nights around a new moon give the best chance of seeing a weak display.
Pick a spot and a time
Choose a place with an open view north and no lights, and be there before 9pm if the outlook is good. The window VisitScotland gives runs to 2am. Give your eyes time to settle and keep phone screens dim.
Bring a camera or phone
A phone with a night mode on a steady surface will often pick up more than you see. Keep exposures long and the camera still.
Plan the drive home
Most of these spots are on single-track roads. Which car park to choose lists prices and rules for the main sites, and a warm layer matters more than you expect after an hour standing still.
Check before you go
- The Kp and the cloud forecast for tonight, not just one of them.
- Whether the car park or road is open after dark. We found no published night-time access for Loch Katrine, Inversnaid or Three Lochs Forest Drive.
- That someone knows where you are, and that your phone is charged. Mobile signal on the single-track roads is not guaranteed.
- The weather where you are standing: the loch shores can be much colder and windier than the road to them.
- That you are not on private land, and not blocking a passing place or a gate.
More planning
Camping on the shore for a night under the sky needs a permit in the summer management zones: camping and motorhome rules has the dates and the map. If you would rather sleep indoors, accommodation around the loch compares the bases.
The aurora is a bonus, not a plan. If the outlook is poor, the same spots work for stargazing on any clear night: the National Park says a dark sky shows over 1,000 stars, against fewer than 100 from a city centre.
Questions people ask
What is the best month to see the northern lights in Scotland?
VisitScotland gives October to March, and BGS says the strongest storms tend to cluster around the spring and autumn equinoxes. In the south of Scotland, including Loch Lomond, the nights around those equinoxes with a clear sky and a strong Kp give the best chance.
Where is the Aurora Borealis visible?
Mainly in a belt around the pole, over Norway, Iceland and Greenland. The UK is south of that belt, so it takes a strong storm to bring the aurora over us. The Met Office says it is sometimes seen as far south as Scotland and Northern England if skies are clear.
Will the Northern Lights be visible in Scotland in 2026?
Nobody can promise a date. NOAA announced in October 2024 that the Sun was at solar maximum, which raises the odds of storms, and it gives no end date. Use the live outlook and the cloud forecast for the night itself.
How long do the northern lights last?
VisitScotland says displays last from a few minutes to several hours. Stay put and keep your eyes adjusted to the dark rather than driving between spots.
Is the aurora visible tonight in Scotland?
Check the live outlook near the top of this page and the NOAA and Met Office forecasts it links to. From Loch Lomond you also need a clear sky to the north, and Kp 6 or more for a faint display.
How likely is aurora tonight?
The live outlook gives the forecast Kp for the next three nights. At the Trossachs' latitude, Kp 6 to 7 may give a faint glow, and Kp 8 to 9+ is needed for the aurora to reach overhead, according to the Met Office.
What time will the aurora be best tonight?
VisitScotland says the best window is 9pm to 2am. Storm timing is hard to predict, so be in place before 9pm and stay as long as the sky is clear.
When to see aurora in Scotland?
October to March, with the equinoxes most active. Check the moon and the cloud for the night as well.
What Kp do you need for northern lights in Scotland?
The Met Office says Kp 8 to 9+ brings the aurora over the UK, and Kp 6 to 7 can make it faintly visible. For Loch Lomond we suggest Kp 6 or more, with a clear northern horizon.
Is Loch Lomond a Dark Sky Park?
No. VisitScotland lists Galloway Forest Park among Scotland's dark-sky sites, and names Loch Lomond & The Trossachs only among other stargazing locations.
