For a population of 10,116 residents, Caernarfon reported 134 crimes in August 2025, equating to 13.3 crimes per 1,000 people—a rate 64.2% above the UK average of 8.1. This disparity underscores the area’s unique challenges, particularly in the context of its geographic and demographic profile. The crime breakdown reveals a stark focus on violent and property-related incidents, with violence and sexual offences accounting for 31.3% of total crimes, followed by anti-social behaviour (23.1%) and shoplifting (12.7%). These figures align with seasonal patterns typical of a coastal town in August, when tourism peaks and local amenities attract both residents and visitors. The high rate of anti-social behaviour may be exacerbated by the influx of transient populations, while shoplifting incidents could be linked to retail activity in the town centre. Meanwhile, violent crimes showed a 27.6% decrease from July, reflecting temporary reductions in alcohol-related incidents or the impact of local policing efforts. However, the persistence of elevated rates for categories like drug offences (159% above the UK average) and possession of weapons (344% above the UK average) suggests deeper systemic issues. These findings are consistent with Caernarfon’s status as a built-up area within Gwynedd, where tourism, seasonal population shifts, and limited resources may contribute to a combination of factors influencing crime. The data also highlights a marked contrast with the UK average for burglary, which was 26% below the national rate, due to heightened community vigilance or the relatively small scale of the built-up area.
