The Météo-France station at Campistrous
Campistrous is 1.4 km east of Lagrange. Every figure on this page is the station’s, not a measurement in Lagrange itself.

- Temperature, rain and day counts: Météo-France’s fiche climatologique for Campistrous, 1.4 km away: statistics for 1991–2020.
- Which station: among stations with at least 24 of the 30 years of temperature and rain, the nearest to the commune’s population-weighted center, counting each 100 m of height difference as 10 km; mainland towns use mainland stations and each overseas département its own.
- Altitudes: the town’s from IGN’s RGE ALTI® at its population-weighted center; the station’s from Météo-France.
- Sunshine: the nearest station with at least 10 years of sunshine records, Campistrous, 1.4 km away.
- Comparisons: every town of 2,500 or more in mainland France, read the same way; the dots are the towns of 2,500+ in Hautes-Pyrénées.
