Examines the effect of weather and temporal factors on the total calls for service (CFS) at the Minneapolis Police Department. Aims at the eventual development of an instrument to predict short‐term variations in CFS over time ‐ a goal which at present is unique. Finds that CFS increase at times when individuals have less habitual routine activities, e.g. after dark; during vacation months. Suggests that temporal factors have much more impact than the weather. Points out some practical implications for the criminal justice system, e.g., future schedules can be adjusted for temporal variations, thus helping in the deployment of officers. Shows that accurate prediction of the overall number of CFS is possible when temporal and weather factors are used.
