Sunset Forecast: May 20-26 — 1 exceptional evening (Thursday!)
Thursday 5/21 is THE night — textbook 38% cloud coverage with stable conditions. The rest of the week is mostly clear skies (pretty, but not dramatic). If you're chasing color this week, block out Thursday evening.

Mid-level clouds at 38% coverage is the sweet spot — enough texture to catch crimson/magenta light scatter, but not enough to block the sun's path. Combined with moderate PM2.5 (from recent air quality readings showing 45-62 AQI), you'll get enhanced reds and purplish tones. Calm 9mph winds = stable atmosphere, which gives you green flash potential if you position on a western horizon with clear ocean sightline (Presidio Park's western edge or descend to a coastal spot 5 min before sunset).
Presidio Park tip: Park at the Serra Museum lot, walk to the western grassy bluff. You're 160 feet up with unobstructed Pacific views, Old Town's terracotta roofs in the foreground, and almost no one knows about this angle. The tourists are all at Sunset Cliffs.
Monday backup: Mount Soledad gives you a different play — watch the sunset color the eastern sky and inland peaks (alpenglow), which most people miss by staring west. The 8% clouds won't be dramatic on the horizon, but the post-sunset glow is reliably gorgeous from up there.

Exceptional sunsets need 30-70% cloud coverage at mid-altitudes (5,000-20,000 ft). Below 20% = boring gradient. Above 70% = the sun gets blocked. This week is mostly high-pressure clear skies (typical May pattern), so Thursday's 38% is an anomaly worth chasing. The PM2.5 particulates currently hovering at moderate levels (45-62 AQI per San Diego APCD data) act as additional scattering agents — they're what turn a nice sunset into a saturated, Instagram-breaking sunset.

Green flash watch Thursday: If you want to attempt a green flash (rare but possible), you need a perfectly clear western horizon at sea level and calm air. Thursday's stable 9mph onshore flow and lack of marine layer make it your best shot this week. Get to coast 10 min early, use binoculars, watch the very last sliver of sun as it dips — the flash lasts 1-2 seconds. Cabrillo National Monument tidepools or Garbage Beach access (local name, south of La Jolla Shores, requires scramble) give you unobstructed ocean horizon.
Shoot Thursday. The rest of the week is fine if you just want a peaceful evening, but it won't be memorable.
