Summary Spatial variability in exponential mean soil temperature for a full year in a newly planted forest in northern England was examined using the sucrose inversion method of temperature measurement. The exponential mean temperature decreased significantly with soil depth ( P < 0.001). The rate of this decrease varied significantly between different areas of the forest with slightly different soil profiles (0.001 < P < 0.01). Exponential means for 30–50cm depth in the forest and comparable arithmetic means for the nearest meteorological stations were similar. Exponential mean temperatures at 5 cm soil depth were, on average, 1.5° higher in the ridges than in the adjacent flat areas ( P < 0.001). The exponential mean for the flat areas was, on average, 0.3° higher to the south‐west of the ridge than to the north‐east (0.001 < P < 0.01). It was also 0.9°C lower than the mean at 5 cm depth in the neighbouring rides (0.001 < P < 0.01).
