Urban spaces offer considerable social, health, environmental, and economic benefits to cities and citizens. As a result, attracting more people to urban outdoor spaces is a goal of sustainable urban planning. This study conducted field surveys in a park in Tianjin, in northern China, to study the impacts of thermal comfort and life patterns on the intensity of activity in urban spaces. Analysis of the data found that subjects who engaged in intense activity were less sensitive to cold than to heat. The attendance of people with children exhibited a very high rate of decrease as the thermal environment became unfavorable. When the thermal environment changed from cold to hot, people in the park adapted by moving from open to shaded spaces. This study revealed that different activities followed distinctive patterns. Intense activity occurred mainly in the afternoon, attending to children occurred primarily in the morning, and low-intensity activity happened all day, but its occurrence decreased at noon. By incorporating the impact of thermal comfort and life patterns, this study developed a mixed-influence model to analyze the hourly usage rate in the park. The findings of this study are useful for designers seeking to create sustainable and attractive open spaces.
