Local sky character in Castro Marim
Northern mid-latitudes · northern hemisphere · 6 m elevation

- About 80.2% of the whole sky rises above the horizon at some point in the year from this latitude.
- The Milky Way's core in Sagittarius culminates about 23.8° up, staying low, so a clear southern horizon matters.
- At 6 m elevation, roughly 0% of the atmosphere's mass is already below you, which measurably reduces extinction near the horizon.
Castro Marim is small enough that local light domes are limited — on a clear, moonless night the Milky Way is realistically within reach.
