Quick Answer
The galactic core, the bright centre of the Milky Way, is visible from roughly February to October in the Northern Hemisphere. The best weeks are late May to mid-July, when it is up for the whole dark night. Go out in the week around new moon, once astronomical twilight has ended, from a place with little light pollution. In June and July the best hours are about 10 PM to 3 AM; by August and September the core is best right after dark.
Why the Milky Way Has a Season
Stars rise about four minutes earlier each night, so over a year every part of the sky takes its turn at night. The galactic core sits in Sagittarius, and from November to January the sun is in front of it: the core is above the horizon only in daylight.
It returns to the pre-dawn sky in February, rises a little earlier each night through spring, is up all night around the June solstice, and by autumn sets soon after dark. How high it climbs depends on your latitude: its highest point is about 90° minus your latitude minus 29°. That is about 24° up from 37°N (Los Angeles, Tokyo) and 21° from 40°N (Denver, Madrid), low over the southern horizon. From Australia, South Africa or Chile it passes almost overhead.
In winter you can still see the fainter outer arms of the Milky Way stretching overhead through Cassiopeia, Perseus and Orion, but the bright core is absent.

Month-by-Month Visibility Guide
Pick your latitude to see the core season, the best weeks, and when the core is up in a fully dark sky each month. It starts at the latitude of your place if you have one set.
Your latitude
40°N · Denver, New York, Madrid, Beijing
- Core season
- Feb 10 – Oct 20
- Best weeks
- May 24 – Jul 12
- Highest it gets
- 21° up
Here is how the season plays out from mid-northern latitudes (about 35–40°N). Clock times include daylight saving time.
February - March
Early Season
Best Time: about 4:30 AM - 6:00 AM, before dawn
The core returns in the pre-dawn sky in February, low in the southeast (10-15° up) and lying almost flat along the horizon. The window is short and ends as dawn breaks. This is for dedicated photographers and early risers; most people should wait a month or two.
April - May
Good
Best Time: 2:00 AM - 5:00 AM (April), midnight - 4:00 AM (May)
The core rises around midnight in the southeast and climbs through the early morning, reaching its full height of about 20-25° before dawn. The window grows to three or four hours. Nights are cool and the air is often clear.
June - July
PEAK SEASON
Best Time: 10:00 PM - 3:00 AM
The best weeks of the year. The core is already up when twilight ends, is highest (about 20-25° from 35-40°N) around midnight, and is still up at 2-3 AM, standing nearly upright over the southern horizon. Late May to mid-July is the stretch when it's up for the whole dark night. Plan your dark-sky trips around the June and July new moons.
August - September
Excellent
Best Time: 9:30 PM - midnight (August), 8:30 - 10:30 PM (September)
Still excellent, and easier: the core is highest as soon as the sky is dark and sets in the southwest before midnight in September. No need to stay up late, which makes these the best months for families.
October
Last Call
Best Time: about 8:00 PM - 8:30 PM, right after dark
The last weeks of the season. The core is low in the southwest (about 10-15° up) once twilight ends and sets within the hour. Good for photographers who want the core low over a foreground.
November - January
Not Visible
Best Time: N/A
The core is up only in daylight. You can still see the fainter outer Milky Way overhead on moonless nights, especially away from city lights.
Best Time of Night
Even during Milky Way season, the time of night matters. Here's what to consider when planning your viewing session.
Wait for Astronomical Twilight to End
The sun needs to be at least 18 degrees below the horizon for true darkness. This is called astronomical twilight. Before this point, residual sunlight scatters in the upper atmosphere, creating a faint glow that washes out faint stars and the Milky Way.
Around the June solstice, astronomical twilight doesn't end until about 10:30-11 PM across much of the northern US and even later in Canada and northern Europe. In May and August it ends around 9:30-10 PM. As a rule of thumb, the sky is fully dark about 90-120 minutes after sunset.
The "Golden Hours" for Milky Way Viewing
For most of the summer, the best viewing happens between 11 PM and 2 AM. During this window:
-
The sky is fully dark (no twilight)
-
The galactic core is at or near its highest point
-
You're looking through less atmosphere (better clarity)
-
Dew hasn't formed yet (clearer optics for cameras and telescopes)
Seasonal Time Recommendations
| Months | Best hours (35-40°N, daylight saving time) |
|---|---|
| February - March | 4:30 AM - 6:00 AM |
| April - May | 1:00 AM - 4:30 AM |
| June - July | 10:00 PM - 3:00 AM |
| August - September | 9:00 PM - midnight |
| October | 8:00 PM - 8:30 PM |
Moon Phase Matters More Than You Think
You can have perfect weather, the right season, and the right time of night, but if the moon is bright you won't see much of the Milky Way. A full moon is about 30,000 times brighter than Sirius, the brightest star, and its light scatters across the whole sky.
New Moon
Ideal - 0% illumination
The moon is not up at night at all. This is the darkest possible sky: the Milky Way is vivid and detailed, showing dust lanes and star clouds. Plan your trips around new moon ±2 days for the absolute best conditions.
Thin Crescent
Excellent - under 25% illumination
A thin crescent is still workable, especially one that sets soon after the sun or rises just before dawn. New moon ±5 days falls in this range.
Quarter Moon
Marginal - 50% illumination
At half illumination the moon is bright enough to wash out the fainter parts of the Milky Way. A first-quarter moon sets around midnight, so the hours after it sets can still be good; a last-quarter moon rises around midnight, leaving the evening dark.
Full Moon
Poor - 100% illumination
A full moon is up all night and brightens the sky like a small city's light pollution. The Milky Way all but disappears. Wait a week for the moon to wane, or plan for a different week.
The Perfect Night Checklist
Use this checklist to judge whether tonight (or any upcoming night) is worth the trip to dark skies. All four should line up.
- Milky Way season? Is the core up in a dark sky at your latitude this month? (Late May to mid-July is peak from the north.)
- Moon out of the way? Is the moon under about 25% lit, or down while the core is up?
- Clear weather? Is cloud cover under 20% while the core is up? (0-10% is ideal.)
- Fully dark? Are you out after astronomical twilight ends, roughly 90 minutes or more after sunset?
All four checked? You've got a Milky Way night, the kind that comes a handful of times a month in peak season. Our forecast checks all four for you, and the dark sky map helps you find a clear, dark spot to go.

Frequently asked questions
What month is best to see the Milky Way?
In the Northern Hemisphere, June and July: the galactic core is up for the whole dark night from late May to mid-July. May and August are nearly as good. In the Southern Hemisphere the best months are May to July, when the core passes almost overhead.
What time of night is the Milky Way visible?
It depends on the month. In April the core rises after midnight and is best in the hours before dawn; in June and July it is up from the end of twilight (around 10 pm) until about 3 am; in August and September it is best in the evening, right after dark. Our forecast gives the exact window for your location every night.
Can you see the Milky Way during a full moon?
Not well. A full moon lights the whole sky and hides all but the brightest parts of the Milky Way. Go out in the week around new moon, or on nights when the moon sets before the sky gets dark or rises after the core has set.
Why can't I see the Milky Way core in winter?
From November to January the galactic core, in Sagittarius, is in the same part of the sky as the sun, so it is above the horizon only in daylight. You can still see the fainter outer Milky Way through Cassiopeia, Perseus and Orion on dark winter nights.
How high does the Milky Way core get?
Its highest point is about 90 degrees minus your latitude minus 29 degrees. That is about 24 degrees up at 37 degrees north, 16 degrees at 45 degrees north and barely clears the horizon at 55 degrees north, but it passes nearly overhead from Australia, South Africa and Chile.
