Data for air temperatures at the old astronomical observatory in Stockholm since 1756 are provided. The data are available both with, and without, adjustments for the urban heat island effect, knowledge about incorrectly calibrated old thermometers, and supposed exposure of old thermometers to radiation. Account is taken for changed routines regarding daily observation time points.

The measured temperatures are on average about 2.3 °C to 2.5 °C warmer after the year 2000 compared to the average before 1900. About 0.8 °C of this warming comes from the local effect of the growing city, while most of the warming is due to the regional climate change over southeastern Sweden.

Data are divided into three separate datasets: (i) individual thermometer observations, (ii) daily mean temperatures, (iii) monthly mean temperatures, also including seasonal and annual means.
