Dominica weather in January begins the dry season for this island that lies between Guadeloupe to the north and Martinique to the south.

But the dry season for Dominica is not very dry.

Dominica lies between Guadeloupe to the north and Martinique to the south. This group of islands in the eastern Caribbean receive more rain throughout the year than most of the destinations in the region. Dominica receives the most of all.

The rain doesn't stop cruise lines from visiting. Dominica has nearly 400,000 visitors a year with most of them coming via cruise ships and a much smaller number who stay overnight, according to the Caribbean Tourism Organization. Only about 6,000 people stay overnight in January.

Heavy rainfall throughout the year makes the island a popular ecotourism destination.

Dominica Rain in January


An average of more than six inches of rain falls in January, the World Weather Organization says.

The average has more in common with the heaviest rains of the year on other islands, especially in September and October.

But six inches is much better than Dominica's worst month of the year. That month is November with an average of 15 inches.

January begins a dry season that goes through April. February usually have the least amount of rain with an historical average of about four inches.

Temperatures in January


Like other Caribbean islands, Dominica's temperatures in January reach a low point of the year at 82 degrees Fahrenheit or about 28 Celsius.

The average low during the month is 71 Fahrenheit or about 22 Celsius. The lows occur mostly at night.

Seawater temperatures will fall between the highs and lows. January temperatures are cool enough that seawater also will feel cool for swimmers.

Whether to Go in January


Dominica is more known for land activities than water activities. The island has beaches but is not known for them.

Regardless, temperatures are cool enough in January to make swimming unlikely.

The lower risk of rain makes January one of the better months to visit Dominica for ecotourism activities such as waterfall and rainforest hikes.

February, March and April will have warmer temperatures and a lower risk of rain. So vacation planners may want to visit then instead.
