Moon Phases Visible from Kapstadt

From Kapstadt at latitude -33.9°, the moon's appearance follows the same 29.53-day synodic cycle visible worldwide — all 8 phases from New Moon through Full Moon and back. However, Kapstadt's mid-latitude latitude affects the moon's maximum altitude in the sky. The moon can reach up to 84.7° altitude when crossing the meridian near summer solstice, and only 27.5° near winter solstice. This seasonal variation determines how high the moon appears above Kapstadt's horizon and affects lunar photography planning.

Kapstadt beherbergt das South African Astronomical Observatory (SAAO) im Stadtteil Observatory — das älteste permanente Observatorium der Südhalbkugel, seit 1820 in Betrieb. Der Tafelberg, der 1.085 Meter direkt hinter der Stadt aufragt, erzeugt ein einzigartiges orografisches Wolkenphänomen namens 'Tischtuch' — eine Wolkenschicht, die entsteht, wenn Südostwinde feuchte Luft die Bergflanke hinaufdrücken und dramatische Sonnenuntergangs-Silhouetten über dem Stadtkessel erzeugen.

Moonrise & Moonset Times at Kapstadt

The moon rises approximately 50 minutes later each day as seen from Kapstadt. This daily delay occurs because the moon orbits Earth eastward at about 1 km/s, moving roughly 13° per day against the background stars. At Kapstadt's latitude (-33.9°), the moon's rise and set positions along the horizon shift seasonally — rising further north in summer and further south in winter. MoonSync calculates exact moonrise and moonset times for Kapstadt using real-time ephemeris data.

Auf 33,9°S feiert Kapstadt seine Dezember-Sonnenwende mit 14 Stunden und 25 Minuten Tageslicht — Hochsommer an der Südspitze Afrikas. Die Lage der Stadt auf einer Halbinsel zwischen zwei Ozeanen (Atlantik und Indik) bedeutet, dass die Sonne über dem Indischen Ozean aufgeht und über dem Atlantik untergeht — ein seltenes geografisches Privileg, das nur eine Handvoll Küstenstädte weltweit bieten können.

Moon Illumination & Kapstadt's Dark-Sky Planning

For stargazing and astrophotography in Kapstadt, moon illumination percentage is the critical number. A Full Moon (100% illuminated) washes out all but the brightest stars and makes deep-sky observation nearly impossible. The 7 days around New Moon (0-15% illumination) provide the best dark-sky window. At -33.9° latitude, combine moon phase with the Twilight Calculator to find nights when both astronomical darkness and minimal moonlight coincide — these 'astrophotographer's golden hours' occur roughly once per month at Kapstadt.

Lunar Data Accuracy for Kapstadt

MoonSync computes moon phase, illumination, moonrise/moonset times, and lunar age for Kapstadt using real-time ephemeris data. Phase illumination is accurate to ±1%. Moonrise and moonset times are calculated from Kapstadt's precise coordinates (-33.9°, 18.4°) and corrected for atmospheric refraction. The Keplerian orbital model used achieves timing accuracy of approximately ±30 minutes over a synodic month. For sub-minute lunar event timing, consult the USNO Phases of the Moon data service.
