Overhead, rising and never-setting constellations for October–December 2026, with a live chart for tonight
The table lists the constellations over Montréal 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 Montréal'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 Montréal 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 Montréal, latitude decides how high each familiar pattern can climb above an ideal horizon.
Latitude-screened constellations for Montréal
Each entry below gives an approximate maximum altitude at meridian transit and a practical season; an asterisk means circumpolar in this simplified centroid model: Perseus: 89.5°, all year *; Ursa Major: 79.5°, all year *; Cassiopeia: 75.5°, all year *; Draco: 70.5°, all year *; Cepheus: 65.5°, all year *; Ursa Minor: 58.5°, all year *; Auriga: 86.5°, winter; Cygnus: 84.5°, summer; Andromeda: 82.5°, autumn; Lyra: 80.5°, summer; Boötes: 74.5°, spring; Gemini: 66.5°, winter; Taurus: 62.5°, winter; Leo: 59.5°, 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 Montréal
Montréal is represented by 45.5088° N, 73.5878° W, in Quebec, using the IANA zone America/Toronto. This is a mid-latitude viewpoint: the relevant celestial pole stands about 45.5° above its horizon. No source elevation is used, so a flat horizon remains the transparent default.
Twelve monthly light estimates for Montréal
The following pairs are approximate daylight / night duration around the 15th of each month: January: 8 h 53 / 15 h 07; February: 10 h 09 / 13 h 51; March: 11 h 37 / 12 h 23; April: 13 h 18 / 10 h 42; May: 14 h 42 / 9 h 18; June: 15 h 28 / 8 h 32; July: 15 h 09 / 8 h 51; August: 13 h 56 / 10 h 04; September: 12 h 18 / 11 h 42; October: 10 h 41 / 13 h 19; November: 9 h 14 / 14 h 46; December: 8 h 32 / 15 h 28. The longest estimated night in this model is December at 15 h 28; the shortest is June at 8 h 32. “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 Canadian dollars (CAD).
Frequently asked questions
What constellations can I see tonight from Montréal?
In mid-October around 9:00 pm: Cygnus, Cepheus, Pegasus, Cassiopeia, Lyra and Andromeda overhead, Perseus, Aries, Cetus and Auriga rising in the east. In mid-November: Andromeda, Cassiopeia, Perseus, Cepheus, Aries, Pisces and Pegasus overhead, Taurus, Gemini and Orion rising.
Which constellations never set from Montréal?
Ursa Major, Ursa Minor, Cassiopeia, Cepheus and Draco stay above the horizon all night, all year, from Montréal's latitude (45.5° N).
Can I see the Southern Cross from Montréal?
No. From Montréal, the Southern Cross never rises above the horizon.
When is the best time to look?
After full darkness (7:47 pm in mid-October, 6:06 pm in mid-November, 5:59 pm in mid-December) and away from the full Moon (October 26, 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 Montréal, Cygnus and Cepheus are overhead in mid-October; by mid-December, Perseus and Aries have taken over and Gemini is rising in the east. Latitude matters too: it decides which groups never rise and which never set.
