June - November is Hurricane Season. December to May is considered Dry Season.  But don't let either of these govern when you come to Barbados since weather has a habit of changing.
BARBADOS CULTURE:
"Barbadians are predominantly very nice and friendly people. Of course as is the case in any country, there are a few bad apples, but don’t let that stop you from having an enjoyable holiday. They don’t dwell a lot on their own history. They like to incorporate the cultures of the British and the Americans into their day to day activities and you could say they are somewhat Americanized. If you want to know more about the culture, visit the official Barbados website."
 
HEALTH AND SAFETY:
"Barbados is one of the safest islands in the Caribbean. There are hardly crimes against visitors, maybe against two or three Brits a year and that is it. You may be offered drugs in the street, but if you decline politely the vendor will leave you alone.  There are also vendors on the beaches who sell anything from aloe vera to necklaces.  Again, a polite refusal usually does the trick. The crime rate is approximately .001%. Take the usual precautions - make sure you lock your doors and windows when you leave your apartment or room, don't carry large sums of cash, and don't walk in unlighted streets late at night. Take care as you would at home and you will be fine."
