Milford Haven’s crime rate in October 2023 reached 8.9 per 1,000 residents, placing it 11.3% above the UK average of 8.0 per 1,000. This marks a notable departure from the area’s usual seasonal patterns, which typically see reduced crime activity during the autumn months. The most prevalent crime types were violence and sexual offences (44.5% of total crimes), followed by anti-social behaviour (17.8%) and criminal damage and arson (10.3%). These figures align with Milford Haven’s characteristics as a coastal town with a mix of residential areas, commercial hubs, and tourist infrastructure. The surge in violent crime may be linked to Halloween-related activity, with darker evenings potentially increasing opportunities for unauthorised gatherings or incidents. Anti-social behaviour rates remained elevated compared to the UK average, consistent with the area’s compact built-up environment where noise and disruptive conduct can spread quickly. The relatively low rates of burglary (2.7%) and shoplifting (4.8%) suggest that retail and residential security measures are functioning effectively, though the drop in vehicle crime (81% below UK average) may reflect reduced car usage during the autumn season. Seasonal factors such as the clocks going back and shorter daylight hours could contribute to the increased prevalence of violent and disorderly crimes, as outdoor activity patterns shift. Residents are advised to remain vigilant, particularly during late evenings, and to report suspicious behaviour promptly.
