Milky Way & night sky
From San Gregorio nude beach, the Milky Way core is visible in a dark sky from March through September. June gives the longest window (about 5.5 hours on a moonless night), and the core peaks around 24° above the southern horizon. Our light-pollution model puts the sky at about Bortle 5 (suburban sky), 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: 5 Bortle 5 — Suburban sky. The Milky Way is weak near the horizon and washed out overhead; long exposures pick up a sky glow. Modeled zenith brightness ≈ 19.94 mag/arcsec².
Weather & best season
Long-term NASA satellite data for this area show October as the clearest month (about 44% average cloud cover) and December as the cloudiest (59%). September is the warmest month and January the coldest, which matters for gear, snow access and how long batteries last at night.

Photography tips for this beach
- Watch for sneaker waves; never turn your back on the ocean on exposed coasts.
- Salt spray coats lenses quickly; wipe often and rinse gear afterward.
- Fog and marine layers can make minimalist images; don't give up on grey days.
- Time visits around low tide to reveal tide pools, sea stacks and reflective sand — check the tide widget below.
- Slow shutter speeds (0.5–2 s) turn receding waves into streaks that lead toward the horizon.
- Check road and trail conditions with the managing agency before you go.
Season: Winter storms bring dramatic surf on Pacific coasts; summer and autumn sunsets are popular on Atlantic and Gulf beaches.
Suggested gear: Tripod, ND filters, Rain cover, Lens cloths. Work out exposures with the depth of field, ND filter and NPF rule calculators.
