The best place to stargaze in Madeira tonight is Paul da Serra plateau, forecast at about 18% cloud between 22:00 and 02:00. The moon is 100% lit, bright enough to drown out the Milky Way, stick to planets, the moon itself and bright clusters. Paul da Serra plateau is a Bortle 2 site at 1450 m. Each site's darkness class comes from VIIRS satellite night-light measurements; the cloud figures are tonight's 22:00–02:00 forecast.

Central-west Madeira · Bortle 2 · limiting magnitude ~6.8
The darkest easily-drivable sky on the island. Open moorland with a clean horizon in every direction and almost no light domes except a faint glow south-east over Funchal.
Access: ER110 road, wide gravel pull-offs; 45 min from Funchal
Central massif · Bortle 3 · limiting magnitude ~6.5
Highest road-accessible point in Madeira and usually above the cloud inversion. Funchal's light dome sits low to the south, so face north for the darkest sky.
Access: Paved road to the summit car park; 40 min from Funchal
North-west, Porto Moniz council · Bortle 2 · limiting magnitude ~6.7
Very dark, but the most fog-prone site on this list, the same moisture that makes the ancient til trees photogenic ruins the seeing on maybe half of all nights.
Access: ER209 off the Paul da Serra road; unlit forestry car park
Above Santana, north coast · Bortle 2 · limiting magnitude ~6.7
North-facing, so the Funchal light dome is fully blocked by the ridge. Best site on the island for northern-sky and aurora-adjacent airglow photography.
Access: Sealed road from Santana to the Pico Ruivo trailhead car park
Western tip · Bortle 3 · limiting magnitude ~6.3
Sea-level horizon over 270°, which makes it the best spot for low southern objects and for catching the Milky Way core setting into the Atlantic.
Access: Drive to the lighthouse, park and walk 200 m clear of the beam
Porto Santo island · Bortle 3 · limiting magnitude ~6.4
Porto Santo is drier and far less cloudy than Madeira, so clear-night odds are the best in the archipelago even though the sky is slightly brighter.
Access: Narrow paved road to the summit viewpoint
Roughly 250,000 people live on an island 57 km long, and almost all of them are on the south coast. The central ridge rises to 1,862 m and physically blocks Funchal's light dome from everything north and west of it, which is why a 45-minute drive takes you from a Bortle 6 city sky to Bortle 2 moorland. Add an Atlantic location with no neighbouring landmass for 700 km and there is no distant glow on the horizon at all.
The catch is cloud. Paul da Serra and Pico do Areeiro often sit above the inversion layer, so the same night can be overcast in Santana and perfectly clear at 1,600 m. That is what the per-spot cloud forecast above is for.
