Pavement-watering is being considered by decision-makers in many cities as a means of cooling the built environment and of adapting to rising extreme heat events due to climate change. In this article we review the existing literature on the topic of pavement-watering. We first focus on the methodological choices made in the literature, including study approach and scale, watering methods used as well as how results are analyzed. We then discuss the cooling effects reported, separating micro-climatic and thermal effects. From the review, we identify common trends in reported results as well as certain common flaws and blindspots. On this basis, recommendations for future work on pavement-watering are made.
