The lowest recorded temperature is -6.1°C, registered in December, while the highest is 34.6°C, recorded in August. Temperatures drop below 0°C only on a few days during winter, while the rest of the year remains relatively mild. With climate change, the need for cooling is becoming increasingly important and will play a larger role in future building designs.
Relative humidity mostly ranges from 60% to 100%, with exceptions such as a few days in March when it dropped below 40%. These variations can affect indoor comfort and influence energy demand for humidification or dehumidification.
The third graph combines three types of solar radiation data: global horizontal, direct, and diffuse horizontal. Visualizing these together provides a deeper understanding of solar exposure. In this case, the building site at MFH Oberwilerstrasse receives consistent solar radiation throughout the year, which benefits passive solar design and energy generation.
Wind data includes both direction and speed. The prevailing wind comes primarily from the northwest, with relatively low speeds, peaking at around 7 m/s. This suggests wind is not a major concern for structural loads but may influence natural ventilation strategies.
Finally, precipitation is unevenly distributed throughout the year, with the highest amounts occurring during summer. Comparing the precipitation and temperature graphs shows that the wettest periods coincide with the warmest months, which may impact drainage design and water management on-site.
By combining the temperature and relative humidity graphs, an inverse pattern becomes clear: during the colder months in Basel, relative humidity tends to be higher. In contrast, in the warmer months, when temperatures reach their peak, relative humidity typically decreases.
