Tempe Butte is a mountain peak in Maricopa County, Arizona at about 444 m (1,457 ft) above sea level. It sits roughly 1.7 km (1.1 mi) NNE of Tempe Junction. It is listed on the National Register of Historic Places.
Tempe Butte (O'odham: ʼOidbaḍ Doʼag) is the official name of an andesite butte of volcanic origin, located partially on Arizona State University's Tempe campus in Tempe, Arizona. It is often referred to by locals as A Mountain, after the 60-foot-tall (18 m) gold-painted letter 'A' near the top. Another name for the area, used by the City of Tempe, is Hayden Butte. The highest point of Tempe Butte stands at 1,495 feet (456 m) in elevation, while its base is at approximately 1,150 feet (350 m) in elevation. Tempe Butte is most often seen as the backdrop to games held in Mountain America Stadium (historically Sun Devil Stadium).From the Wikipedia article “Tempe Butte”, licensed under CC BY-SA 4.0.

Golden hour & blue hour by month
Summits catch first and last light — alpenglow can turn rock pink or orange minutes before sunrise and after sunset while valleys stay in shadow.

Local time (America/Phoenix), including daylight saving time. Golden hour runs from about −4° to +6° solar altitude, so the morning golden hour begins during blue hour, before sunrise.
Milky Way & night sky
From Tempe Butte, the Milky Way core is visible in a dark sky from February through October. June gives the longest window (about 6.2 hours on a moonless night), and the core peaks around 28° above the southern horizon. Our light-pollution model puts the sky at about Bortle 9 (inner-city 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: 9 Bortle 9 — Inner-city sky. Only the Moon, planets and a few bright stars are visible. Modeled zenith brightness ≈ 17.96 mag/arcsec².
Weather & best season
Long-term NASA satellite data for this area show June as the clearest month (about 18% average cloud cover) and July as the cloudiest (49%). July 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 mountain peak
- Clouds around the summit add drama — a clear blue sky is often the least interesting condition.
- Photograph the peak from a lake, meadow or ridge at sunrise when the face that looks east lights up first.
- Long lenses compress ridgelines; shoot the peak from several miles away to make it look massive.
- Afternoon thunderstorms are common in summer at high elevations — plan summit hikes for early morning.
- Snow on the summit holds detail best when you expose for the highlights and lift shadows later.
- Check road and trail conditions with the managing agency before you go.
Season: Early summer keeps snow on the peaks with green valleys below; autumn adds aspen or larch color in many ranges.
Suggested gear: Telephoto lens, Lightweight tripod, Warm layers, Microspikes in shoulder seasons. Work out exposures with the depth of field, ND filter and NPF rule calculators.
