Abstract: As the climate becomes more extreme and heat waves become more prevalent, the effects of climate change spill over into previously unnoticed areas. One such prominent result of global warming is the adverse effect of outdoor weather on pedestrians at night. To investigate this rather overlooked effect, we carried out a large-scale field study in 232 different locations in three different cities in Israel–Tel Aviv-Yafo (106 locations), Haifa (49 locations), and Beersheba (77 locations). The study, involving 30,216 observations on the feeling/s of safety (FoS) performed by 491 participants, started in August 2019 and lasted almost one year. As the study reveals, people feel safer, with all other factors being constant, when the temperature is moderate and humidity is high. According to the study findings, if temperature increases from 25 °C to 30 °C, illumination should be increased by ~20 lx to maintain the same level of FoS. However, if the temperature drops, less illumination can be supplied, which makes a case for smart illumination policies. As providing sufficient FoS is important for an active life outdoors, this study generates knowledge that can help support active and secure mobility in urban areas and beyond. As temperatures rise and humidity patterns change, our findings may have broad implications for urban areas worldwide, both in Israel and beyond.
