A Dark Sky Community among red rocks — and Arizona keeps the same clock all year.

Stargazing at Centennial TrailheadForecast
Wait for 03:00–05:28 for general stargazing: less cloud (≈46% earlier → ≈7% in the window).
Plan a short look for bright stars; this is not a Milky Way, planet or meteor timing recommendation. Check the latest weather before travelling.
The Tonight engine selects this window because the sky holds clear, Moonlight doesn't affect the best viewing window. Compared with earlier remaining scored hours: less cloud (≈46% earlier → ≈7% in the window). Earlier observing is not ruled out.
Window cloud ≈7%; whole-night mean 32%. Moon altitude in the scored hours: -22°–1°. Cloud, darkness, Moon altitude and rain affect the timing; a full Moon can remain up throughout.
Go means conditions are usable; Wait is shown only when remaining earlier scored hours support a timing improvement; Later window means there is no demonstrated reason to delay. Neither label ranks places. The window is selected by hourly cloud, darkness, Moon altitude and rain, with whole-night context in the verdict. It is not a guarantee or proof that earlier hours are unusable. Artificial light, terrain, access and personal safety are not scored. The former confidence percentage was an uncalibrated internal heuristic using forecast coverage, cloud variation, rain and score margin — not the probability of clear weather or a successful outing. It is no longer shown here.

Each place has its own forecast and calculation. Go and Wait describe timing, not a ranking of places. Compare the chosen window, not only the whole-night cloud average. Artificial light and access rules are not scored; a place marked “Sky conditions only” is not a visit recommendation.

Astronomical darkness
Astronomical darkness begins at 18:55. Faint-star and Milky Way visibility also depends on cloud, Moon, artificial light and the local horizon. Morning: darkness ends 05:28, sunrise 06:54.
Times in America/Phoenix (MST, UTC−7). No daylight saving time in this zone.
Fri 6 NovAstronomy
The Moon is below the horizon in the sampled dark hours; cloud and local lighting still affect the sky.
Galactic centre in SagittariusAstronomy
The window needs astronomical darkness and the core at least 5° up. Core positions include refraction and are sampled each minute; these are timing estimates, not guaranteed visibility. Hills, trees and town glow near the horizon can still hide it.
Above the horizon vs. easy to seeAstronomy
"Favourable geometry" means at least 10° up while the Sun is 12° or more below the horizon. Cloud, Moon and local obstructions are not included; positions are sampled every 15 minutes.

Rates are approximate modelled estimates, not measured or guaranteed counts. Observing windows use 30-minute samples: any start or end is approximate and may differ by almost 30 minutes from a continuous crossing. Radiants use fixed peak positions; daily radiant drift is not modelled. The model assumes a fixed, moderately dark sky; town light can cut what you see well below these figures.
Coming upAstronomy
Year-specific IMO predictions, not guaranteed or observed peaks. Date-only maxima are not assigned an invented local hour. The rate model above still uses typical annual peak dates and fixed radiant positions; it does not model the published peak ranges or daily radiant drift.
Lowest-cloud evening (weather only): Sat 7 Nov (lowest mean night cloud). The overall recommendation at the top also weighs moonlight and darkness, so it can name a different night. Cloud is shown only where the forecast covers the night. Values come from an eight-day forecast — the later evenings are less certain than the first, so check again close to the date.

Astronomy only. No weather is given for this selected date. Moon-up percentages are approximate 15-minute samples across astronomical darkness; Milky Way positions include refraction and one-minute sampling, not visibility guarantees.
Astronomy on the 15th of each month — not a weather or climate forecast. Each core window uses astronomical darkness and its stated altitude threshold (10°, or a lower 5°/2° threshold when the core stays low). Low-altitude windows are marginal geometry, not equivalent to a 10° window or a visibility recommendation.Astronomy

Visit Sedona states that Sedona was designated an International Dark Sky Community in 2014. Its stargazing guide recommends Centennial Trailhead, Baldwin Trailhead and Beaverhead Flat Scenic Overlook.
Source: Visit SedonaVisit Sedona describes Centennial Trailhead as a prime viewing location with little to no light pollution, reached by a paved trail (the tourism page lists 0.7 miles), and less crowded than some alternatives.
Source: Visit SedonaVisit Sedona recommends arriving before sundown because Centennial Trailhead also offers a scenic Sedona vista. Bring a blanket for your observing stop.
