June 2023 marked a significant increase in crime rates for Caernarfon, a historic coastal town in north-west Wales, with the overall crime rate reaching 12.2 per 1,000 residents—43.5% above the UK average. This surge was driven by violence and sexual offences (29.3% of all crimes), anti-social behaviour (22.0%), and criminal damage and arson (13.8%). The data aligns with seasonal patterns typical of summer months, when tourism begins to rise in coastal areas, potentially increasing foot traffic and associated risks. However, the sharp contrast between Caernarfon’s figures and the UK average suggests local factors may be at play. Violence and sexual offences. from May’s 63 incidents, still remain 23% above the UK average. Anti-social behaviour, which rose 82% above the national benchmark, could be linked to the town’s compact built-up area, where noise and disorder may amplify in warmer weather. Criminal damage and arson, 166% above the UK average, may reflect a combination of local economic challenges and seasonal neglect of properties during summer absences. These trends underscore the need for targeted community engagement, particularly in areas with high foot traffic, to address emerging patterns before they escalate further.
