Northern lights in Duvall

Duvall needs an active night: from about Kp 4.7 the aurora appears low over the north-north-east horizon, and it rises higher as activity grows. Since 1995 that level (Kp 4.7) was reached during darkness here on 877 nights.

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.

  1. Kp 0–2 Quiet Only under the auroral oval: northern Norway, Swedish and Finnish Lapland, Iceland, Alaska, northern Canada.
  2. Kp 3 Unsettled next 24 h camera in Duvall Bright in the Arctic; low on the horizon in central Scandinavia and southern Iceland.
  3. Kp 4 Active Overhead in the Arctic; low in the north from southern Norway, Sweden, Finland and northern Scotland.
  4. Kp 5 Minor storm (G1) eye in Duvall Scotland, southern Scandinavia, the Baltic states, the northern US states and southern Canada.
  5. Kp 6 Moderate storm (G2) Northern England, Denmark, northern Germany and Poland, the US Midwest — often clearer in photos than to the eye.
  6. Kp 7 Strong storm (G3) Most of the UK, the Netherlands, Germany, Poland, Czechia; red glow in photos from France and the northern Alps.
  7. 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.
  8. 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

Rural to suburban. Some sky glow from nearby lights. Moderate displays are fine; faint ones are easier a few kilometres out.

A noticeably darker area starts about 10 km to the 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 5° above the horizon towards the north-north-east. That hides low aurora: here you need about Kp 4.7 instead of Kp 4.7. A hilltop, shore or open field with a clear view to the north-north-east helps.

Questions and answers

What Kp do you need to see the aurora in Duvall?

Duvall needs an active night: from about Kp 4.7 the aurora appears low over the north-north-east horizon, and it rises higher as activity grows.

Which way should I look for the aurora in Duvall?

Face north-north-east (about 16° from true north). At Kp 4.7 the lower edge of the aurora sits roughly 13° above the horizon; stronger activity lifts it higher and further across the sky.

What is the best month to see the aurora in Duvall?

Over 2005–2025, September gave the best odds in Duvall (5% of nights dark, active enough and mostly clear), followed by April (3%).

When is the aurora season in Duvall?

Duvall 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 Duvall?

Some sky glow from nearby lights. Moderate displays are fine; faint ones are easier a few kilometres out. A noticeably darker area starts about 10 km to the east.

When was the aurora last possible in Duvall?

The most recent night in our data when activity reached the level Duvall needs, during darkness, was 4 October 2026 (Kp 5.0). It has happened on 877 nights since 1995.
