About 79.8% 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 24.4° up, staying low, so a clear southern horizon matters.
At 49 m elevation, roughly 1% of the atmosphere's mass is already below you, which measurably reduces extinction near the horizon.
