Tonight in Surrey
1%
Peak chance of a visible display tonight, from the same model the Revon app runs. Surrey needs Kp 7 to see anything at all, and tonight the forecast peaks at Kp 4.7. Short of the threshold, which is what most nights look like here.

The next 30 nights in Surrey
Every night to come, scored the same way as tonight. The best of the open week is Sunday 2 Aug at 1%. Not one of the seven reaches the Kp 7 that Surrey needs, which is normal rather than unlucky — it averages 3.1 viable nights a year. The 23 nights past the seven-day window move with the 27-day solar rotation and are updated daily in the app.

Wait for an alert; do not book a week
At Kp 7, Surrey needs a severe geomagnetic storm before anything shows above the northern horizon. Storms that size arrive a handful of times per solar cycle and announce themselves a day or two ahead. Watching for one beats picking dates and hoping.

Solar declination and hour angle at −18°
Nothing to see from June
Through those months the sun never falls more than 18° below the Surrey horizon, so the sky never darkens fully. Plan around the darker half of the year.
Getting clear of the light
With 568,322 people around you, the sky over central Surrey is Bortle 8. The glow hides anything but the brightest display, so the drive out matters more here than the forecast does.

The months that actually deliver
Counting only nights that were both stormy enough and dark enough, May, September and August came out ahead in Surrey. That is storm season and darkness overlapping — the equinoxes tend to be geomagnetically active, and the nights are already long by then.
Darkest nights of the coming year
A bright moon washes out a weak display as effectively as street lighting. These new moons fall inside the Surrey viewing season.

Where the horizon opens up near Surrey
The display sits low on the northern horizon, so what beats a better forecast is open ground facing that way. Height gets you above the town glow; water gives you an unbroken skyline. These are within a short drive of Surrey.

What to do with the daylight
Aurora watching is a night job, and in winter that leaves a short, bright day to fill. Close to Surrey you will find HVDC Vancouver-Island - Metallic Return Branch, KLYN-FM (Lynden) and KARI-AM (Blaine), and for a day when the cloud sits low, Semiahmoo Park Maritime Museum are indoors and near by.
Keep the daylight loose: the sky decides the evening, and the forecast can turn within a few hours.

Where to stay
Staying central in Surrey is fine for everything except the aurora itself — you will still need to drive out. If seeing it matters more than convenience, base yourself on the edge of town facing your dark spot.

Common questions about the aurora borealis in Surrey
Can you see the aurora borealis from Surrey?
Yes. On the last 10.0 years of NOAA Kp records, Surrey had about 3.1 nights a year when the storm was strong enough and the sky dark enough at the same time.
What Kp index do you need to see the aurora borealis in Surrey?
Kp 7. Surrey sits at geomagnetic latitude 54.5°, and the auroral oval only reaches that far from the pole once activity hits Kp 7. Storms that size occur about 3.2 nights a year.
When is the best time of year to see the aurora borealis in Surrey?
May, September and August. Those months scored highest once both conditions are counted together: geomagnetic activity and enough hours of real darkness. From June the sky over Surrey never gets fully dark, so nothing is visible however strong the storm.
Where can you escape the light pollution near Surrey?
The centre of Surrey reads Bortle 8. The nearest sky at Bortle 4 is about 44 km north around Electoral Area A. On a marginal night that drive matters more than the forecast does.
Where is the nearest place to Surrey with reliable aurora borealis?
Juneau, United States — 1,272 km north-north-west. It needs only Kp 5 and averages 28.7 viable nights a year against 3.1 in Surrey.
