Night sky tonight in Warsaw

Tonight's Sky in Warsaw — 2026-09-24

Bottom line: Tonight is a washout for deep-sky observing. The story is the weather, not the stars — heavy cloud cover and precipitation dominate the entire forecast window, and the 92%-illuminated Waxing Gibbous Moon isn't doing you any favors either.

Hour-by-Hour Conditions

• 00:00 (midnight): 11.3°C, 83% cloud cover, light rain (7 mm), wind 2.6 m/s, visibility 13.4 km. Conditions fail your threshold — cloud cover is more than double the 40% limit.
• 01:00: Essentially unchanged — 11.0°C, still 83% clouds, continued precipitation, wind easing slightly to 2.1 m/s, visibility dropping to 11.6 km. No clearing trend in sight.

The forecast shows a static, overcast night: temperatures slowly falling through the low 11°C range, winds light and diminishing, but the cloud deck stubbornly parked overhead.

The Moon & Planets

• Moon: Waxing Gibbous at 92% illumination, rising at 17:39 and up until 03:24. It's the dominant object in the sky — beautiful in its own right, but it will bleach out faint fuzzies even if the clouds part.
• Saturn (mag 0.34): Your best planetary target — transiting due south around 01:08. If you catch a break in the clouds, its rings are worth the wait.
• Uranus (mag 5.65): Transits at 04:33, but at magnitude 5.7 it's a tough catch through clouds and city glow — a binocular or small-scope challenge only if skies clear.

If the Clouds Part

With Bortle 9 inner-city skies and a bright Moon, stick to the heavy hitters:

• M31 (Andromeda Galaxy, mag 3.4) — the brightest galaxy in the northern sky
• M45 (Pleiades, mag 1.6) — a naked-eye cluster rising in the east
• M13 (Hercules Cluster, mag 5.8) — still well-placed in the west

Missed Opportunity

The evening's real highlight was a bright ISS flyby at 19:34 — already passed by now. Keep an eye on the app for the next pass; those are always worth planning around.

Practical advice: Tonight is a good night for catching up on equipment maintenance or planning a session for a clearer evening. The Moon is heading toward Full (age 12.9 days), so the next couple of weeks favor planetary and lunar observing over deep-sky.
