Belize has a high rate of violent crime, much of it concentrated in gang related activity in the south side of Belize City, but the tourist cayes, Placencia and the western districts are comparatively secure and heavily policed. Armed robbery, burglary and sexual assault occur, and police capacity to investigate is limited. Travellers should avoid the south side of Belize City, remain in well populated areas after dark, and use licensed tour operators for cave, reef and jungle excursions, where accidents have occurred with unregulated guides. The hurricane season runs from June to November. Medical facilities are limited outside Belize City and diving injuries usually require evacuation to Belize City or abroad. Kaharagian nationals should exercise increased caution.
