Overhead, rising and never-setting constellations for October–December 2026, with a live chart for tonight

The table lists the constellations over San Antonio for each month of October–December 2026; the live chart then shows tonight's sky for the city or your exact location, with the Moon and planets. Both are free.

Why choose Starry Memory

  • Computed for the city's sky — The lists are calculated for San Antonio's latitude and local evening time, month by month, not copied from a generic seasonal chart.
  • Overhead, rising and setting — Knowing where a constellation stands helps you find it: overhead ones are the easiest, rising ones climb through the evening, setting ones are best early.
  • Never-setting groups — The circumpolar constellations of San Antonio are listed: they are there on any clear night of the year.
  • Live chart for tonight — The chart below recomputes the constellations, the Moon and the planets for tonight and for your exact location.

From San Antonio, latitude decides how high each familiar pattern can climb above an ideal horizon.

Latitude-screened constellations for San Antonio

Each entry below gives an approximate maximum altitude at meridian transit and a practical season; an asterisk means circumpolar in this simplified centroid model: Draco: 54.4°, all year *; Cepheus: 49.4°, all year *; Ursa Minor: 42.4°, all year *; Boötes: 89.4°, spring; Lyra: 83.4°, summer; Gemini: 82.6°, winter; Andromeda: 81.4°, autumn; Cygnus: 79.4°, summer; Taurus: 78.6°, winter; Auriga: 77.4°, winter; Leo: 75.6°, spring; Perseus: 74.4°, winter; Orion: 65.6°, winter; Ursa Major: 63.4°, spring. This is a planning guide, not a promise that every star will be visible from a bright street. Date, hour, local obstructions and light pollution still matter. The live sky tool performs the date-specific projection that a static latitude table cannot.

For constellation screening, latitude difference becomes a meridian-altitude difference; a small change is reported as small rather than exaggerated for local copy.

The astronomical fingerprint of San Antonio

San Antonio is represented by 29.4241° N, 98.4936° W, in Texas, using the IANA zone America/Chicago. This is a tropical viewpoint: the relevant celestial pole stands about 29.4° above its horizon. The source elevation is 198 metres; terrain can hide a low object even when the geometric calculation says it rises.

Twelve monthly light estimates for San Antonio

The following pairs are approximate daylight / night duration around the 15th of each month: January: 10 h 19 / 13 h 41; February: 10 h 59 / 13 h 01; March: 11 h 47 / 12 h 13; April: 12 h 43 / 11 h 17; May: 13 h 28 / 10 h 32; June: 13 h 52 / 10 h 08; July: 13 h 43 / 10 h 17; August: 13 h 04 / 10 h 56; September: 12 h 10 / 11 h 50; October: 11 h 16 / 12 h 44; November: 10 h 29 / 13 h 31; December: 10 h 07 / 13 h 53. The longest estimated night in this model is December at 13 h 53; the shortest is June at 10 h 08. “Night” here is the complement of daylight on a flat horizon. Civil, nautical and astronomical twilight are not interchangeable, and weather is not predicted by this table.

What the calculation does — and does not claim

Coordinates, date and local time feed the same astronomical workflow used by the poster. The HYG catalogue provides star entries, while Astronomy Engine calculates moving bodies. The page does not claim that city-centre coordinates equal a hospital, venue or home: selecting an autocomplete suggestion replaces the shortcut with that location. It also separates astronomical geometry from weather and light pollution, so a correct map never becomes a claim that the ground-level sky was cloudless.

Free gyroscope first, optional poster second

On a compatible phone, the gyroscope turns the calculated sky into a movable window: tilt and rotate to explore, with star names shown beside key points. That experience is free. If a date deserves a keepsake, the same place can continue into the editor. The protected preview remains watermarked before payment; the €3.99 purchase unlocks the 4960 × 7016 px, 300 DPI file. Physical formats appear only when availability, delivery supplement and timing can be checked for the destination. Checkout is in euros; the card issuer shows the current conversion to US dollars (USD).

Frequently asked questions

What constellations can I see tonight from San Antonio?

In mid-October around 9:00 pm: Cygnus, Pegasus, Lyra and Aquila overhead, Aries, Perseus and Cetus rising in the east. In mid-November: Andromeda, Pisces, Pegasus, Cassiopeia and Aries overhead, Taurus, Auriga, Eridanus and Orion rising.

Which constellations never set from San Antonio?

Ursa Minor and Cepheus stay above the horizon all night, all year, from San Antonio's latitude (29.4° N).

Can I see the Southern Cross from San Antonio?

Only low in the south: the Southern Cross reaches at most 1° above the horizon from San Antonio, best on spring evenings.

When is the best time to look?

After full darkness (8:22 pm in mid-October, 7:00 pm in mid-November, 7:02 pm in mid-December) and away from the full Moon (October 25, November 24, December 23). The new Moons of October 10, November 9, December 8 give the darkest skies.

How do I find constellations from a city?

Start from the brightest stars, let your eyes adapt for 15 to 20 minutes, and look for the main outline rather than every star. Light pollution hides faint stars, so patterns such as Cassiopeia's W or Orion's belt are the easiest first targets.

Why does the sky change during the year?

The stars rise about four minutes earlier each night, so the evening sky shifts by about two hours a month as the Earth orbits the Sun. From San Antonio, Cygnus and Pegasus are overhead in mid-October; by mid-December, Aries and Andromeda have taken over and Orion is rising in the east. Latitude matters too: it decides which groups never rise and which never set.
