Tropical Storms in the Dominican Republic
The Dominican Republic is located squarely within the hurricane belt. In fact, hurricanes claim a special history in the Dominican Republic, originated from the indigenous Taino people’s word for the fierce and destructive storms that can batter the island: “hurakans.” When Europeans arrived in the Dominican Republic in the 16th century, they had never seen weather to equal a tropical storm and had no word for them. Hurakan quickly became a borrowed word and was incorporated into Spanish as huracán. Hurricane is the anglicized form.
Hurricane season in the Dominican Republic is from June to November. Historically the most active months are September and October, but some of the most severe storms have come significantly earlier in the year; it’s impossible to predict when the storms will come. Most of the time this is only known within days before arrival, and still anything could change. While a major storm hits once every quarter-century, the island is affected by at least outer bands of storms more frequently, close to every five years. Weather in the Dominican Republic is on average very good, therefore we would recommend a visit year round.
