A new study focusing on the Gush Dan region—which includes cities such as Tel Aviv, Bnei Brak, Ramat Gan, Bat Yam, Holon, and Rehovot—has highlighted a significant temperature disparity between urbanized environments and open land. The research identifies industrial zones and heavily built-up areas as the primary locations where this 'heat island' effect is most pronounced.

According to the findings, the density of construction and the prevalence of industrial infrastructure contribute to a measurable increase in local temperatures. During the summer months, these built-up areas can reach temperatures 4°C higher than those recorded in nearby open, undeveloped spaces. The discrepancy is even more extreme during the winter, where the study reports temperature differences of up to 9°C.

The study underscores the environmental impact of urban planning and development in the region. By concentrating buildings and industrial facilities, these municipalities are creating microclimates that retain more heat than natural landscapes. While the report provides specific temperature data, it focuses primarily on the physical phenomenon of heat retention in urban settings rather than proposing specific policy changes or mitigation strategies for the affected cities. The findings serve as a technical assessment of how the current layout of the Gush Dan metropolis influences local weather patterns and thermal comfort for residents living in these high-density zones.
