Long-term monthly averages for temperature, precipitation, humidity, wind, and daylight

Climate Profile and Monthly Weather Normals for Südhänge des Neckartales, Berghänge des Haugenloches, Alte Bildechinger Steige, Altheimer Tal und angrenzende Hochflächen

Annual climate patterns for this Baden-Württemberg landscape are derived from a representative elevation point using NASA POWER data covering 1991 to 2020. This profile provides twelve-month averages for daily temperature, precipitation rates, relative humidity, wind speed, and daylight hours. These figures represent historical norms rather than current weather or forecasts, facilitating geographic comparison of atmospheric conditions across the region.

A deep winter-to-summer temperature rise with precipitation highest in July

Southern Neckar slopes and Altheimer valley annual climate pattern

The southern Neckar slopes, Haugenloch hillsides, Altheimer valley, and adjoining plateaus have a 1991–2020 mean-temperature rise from -0.8°C in January to 18.1°C in July. At one point near 556 metres, average minima and maxima add the daily range while precipitation moves from 1.94 mm/day in April to 3.13 mm/day in July, describing climate normals rather than uniform terrain conditions.

Twelve-month climate

Long-term temperature, precipitation, humidity, wind, and daylight at one point

Southern Neckar slopes and Altheimer Tal monthly climate comparison

The southern Neckar slopes, Haugenloch hillsides, Altheimer Tal, and adjacent plateaus have 1991–2020 monthly climate normals from a representative point near 556 metres. The twelve records compare average temperature limits and daily precipitation with humidity, wind, and calculated daylight without extending one coordinate across every valley, slope, and plateau.

Southern Neckar slopes and Altheimer valley monthly climate highlights

The southern Neckar slopes, Haugenloch hillsides, Alte Bildechinger Steige, Altheimer valley, and adjoining plateaus use 1991–2020 monthly averages to establish seven climate leaders. Calculated near 556 metres, the comparison distinguishes warm, cool, wet, dry, humid, windy, and bright periods without asserting records or identical exposure across this varied terrain.

Compare the southern Neckar slopes and Altheimer valley climate across parks

The southern Neckar slopes, Haugenloch hillsides, Altheimer valley, and adjoining plateaus provide a varied-terrain baseline for comparing temperature and precipitation by month. Standard humidity, wind, and daylight records support wider cross-park analysis, without implying that candidates share these exposures, the same climate, equal elevation, or geographic closeness.
