Satellites Visible from Montevideo
Tonight
Satellite viewing from Montevideo on the night of 23 August 2026 is rated FAIR NIGHT: 2 visible ISS, Tiangong or Hubble passes, the best reaching 29° above the horizon. The best window for satellite spotting over Montevideo on 23 August 2026 is 18:37–20:32 and 05:17–06:41 GMT-3, when most satellites are still catching sunlight. Between those windows the sky is dark but the majority sit inside Earth’s shadow. Individual satellites in lower orbits can be visible a little outside these times. The best pass of the night is picked from live orbital data — the one that climbs highest and stays visible longest.
At 9pm local on 23 August 2026 from Montevideo, Venus is in the west, about 1 fist above the horizon. Planets shine with a steady light, unlike satellites, which cross the sky in a few minutes.
Montevideo (34.9°S) — the ISS can climb high overhead here, giving bright, well-placed passes.
Montevideo, Uruguay offers excellent satellite visibility. The ISS and Tiangong both pass high overhead here, and the AST BlueBirds are visible too. Hubble stays low in the north and needs a clear horizon. OrbitalNodes.ai shows you exactly when and where to look, personalised to your exact location.
Observing notesEvening twilight begins 30 min after sunset, morning 45 min before sunrise. Best viewing away from the city-centre light dome, toward darker outskirts — best April to September, through the clear austral winter.

At 34.9°S, the sky over Montevideo has a geometry all its own. Your best target is the ISS: at magnitude −4 it outshines the glow, delivering high passes from 35° several nights a week. China’s Tiangong, on a 41.5° inclination, also rides high from here — a second naked-eye station over the city.
The stations are just the start — the same latitude arranges the rest of the sky. The Milky Way's core rides almost overhead — culminating about 84° up toward the north — though from the city its glow is mostly lost to light pollution; an hour out toward darker skies brings it back. The Magellanic Clouds are circumpolar, circling the pole all night — though you'll need to escape the city lights to make out the two faint galaxies. Polaris never rises; the Southern Cross and the unmarked south pole, about 35° up, are your guides. The clearest, longest nights here fall through the austral winter, May to August.
Montevideo’s temperate climate clears most reliably in the settled autumn spells; the Atlantic keeps summer nights mild but sometimes hazy.
SATELLITE SPOTTING FROM MONTEVIDEO
When can I see the ISS from Montevideo?
The ISS appears during twilight — roughly 30 to 60 minutes after sunset or before sunrise. From Montevideo's latitude of 34.9°S the best passes climb nearly overhead, and the brightest take four to six minutes to cross. Check OrbitalNodes for the exact times and the compass direction to look.
What satellites are visible from Montevideo?
From Montevideo the headline targets are the ISS (magnitude −4, the brightest), Tiangong, the Hubble Space Telescope and the AST BlueBird satellites. Fresh Starlink trains can also put on a show in the days after a launch.
Where is the best place to watch satellites in Montevideo?
The bright stations cut through city glow, but fainter targets reward darker ground. Even 30 to 60 minutes beyond Montevideo's light dome makes a dramatic difference. The Southern Cross and the southern sky help you orient.
Can I see satellites from Montevideo city centre?
Yes. At magnitude −4 the ISS punches straight through Montevideo's light pollution and needs no equipment, and Tiangong usually shows from the centre too. Only the fainter satellites really need darker skies.
Does Montevideo's latitude make it good for satellite spotting?
Yes — 34.9°S is a strong latitude, with high, bright ISS passes nearly overhead and access to a wide spread of orbits. Tiangong, China's space station, can also ride high here and is an easy second naked-eye target.
What is the best season for satellite spotting in Montevideo?
April to September is best — the austral winter brings the longest, clearest nights, with June and July at their peak.
Montevideo sits in the Southern Hemisphere — and when EARENDIL-1 launches, its steerable mirror could illuminate targeted cities during passes. Track space-mirror passes on OrbitalSolar.ai →
