For a population of 28,942, Penarth recorded 162 crimes in September 2023, equating to 5.6 crimes per 1,000 residents. This rate is 30% below the UK average of 8.0, marking a significant contrast to national trends. The most common crimes were violence and sexual offences (54 cases, 33.3% of total), followed by criminal damage and arson (23 cases, 14.2%) and public order offences (19 cases, 11.7%). These figures align with seasonal patterns typical of a coastal commuter town, where the start of the academic term and extended evenings may influence crime dynamics. Violence and sexual offences, though the most frequent category, remain 31% below the UK average, suggesting a lower prevalence of interpersonal conflict in Penarth compared to other areas. Criminal damage and arson, however, exceed the UK rate by 33%, possibly linked to increased property-related incidents during the transition from summer to autumn. The area’s relatively low overall crime rate, despite higher-than-average property damage, indicates a combination of local demographics and environmental factors. As a built-up area within the Vale of Glamorgan, Penarth’s crime profile reflects a balance between urban activity and the influence of surrounding rural zones, with seasonal shifts likely contributing to fluctuations in specific crime categories.
