Golden hour & blue hour by month
Lighthouses work at both ends of the day: blue hour when the beacon is lit, and golden hour when white towers take on warm tones.

Milky Way & night sky
From Mukilteo Light, the Milky Way core is visible in a dark sky from April through July. June gives the longest window (about 1.3 hours on a moonless night), and the core peaks around 13° above the southern horizon. Our light-pollution model puts the sky at about Bortle 7 (suburban / urban transition), so expect visible sky glow; drive away from towns for better results.

Window when the galactic core is at least 10° high during astronomical darkness on the 15th of each month. Pick nights within a few days of the new moon. Plan exact nights with the Milky Way planner.
Estimated sky darkness: 7 Bortle 7 — Suburban / urban transition. The whole sky has a grey-white glow; the Milky Way is invisible to the eye. Modeled zenith brightness ≈ 18.8 mag/arcsec². Aurora needs roughly Kp 4.5+ to show low on the northern horizon here.
Weather & best season
Long-term NASA satellite data for this area show July as the clearest month (about 46% average cloud cover) and January as the cloudiest (80%). August is the warmest month and December the coldest, which matters for gear, snow access and how long batteries last at night.

Photography tips for this lighthouse
- Moonrise or the Milky Way over the tower makes a classic night composition; plan with the azimuth tables.
- During blue hour, use 5–15 second exposures to capture the beam; check whether the light is still active.
- Shoot from the beach or a jetty to place the tower against open sky and sea.
- Stormy weather and crashing surf add drama; keep a safe distance from waves on rocks and piers.
- A telephoto from across a bay compresses the tower against cliffs or the moon.
- Tell someone where you're going in remote areas and carry the ten essentials.
Season: Summer brings open towers and tours; autumn and winter offer storms, fewer crowds and lower sun angles.
Suggested gear: Tripod, Telephoto lens, ND filter for smooth water, Rain cover. Work out exposures with the depth of field, ND filter and NPF rule calculators.
Tides
The nearest NOAA tide prediction station is Glendale, Whidbey Island, 3.9 km (2.4 mi) away. Low tide often reveals tide pools, wet-sand reflections and sea stacks.
