The Météo-France station at Saint-Gladie
Saint-Gladie is 7.3 km south-west of Orion. Every figure on this page is the station’s, not a measurement in Orion itself.
| Station (Météo-France number) | Saint-Gladie (64480001) |
| Distance from the town | 7.3 km south-west |
| Station altitude | 73 m |
| Town altitude (its center) | 216 m |

Orion sits 143 m higher than the station. Air usually cools by about 0.65°C every 100 m, so expect Orion to run about 0.9°C cooler than these figures.
TownRatings matches each commune to one station with at least 24 years of temperature and rain records: the nearest, counting every 100 m of height difference as 10 km, never across the sea.
