On the Samana peninsula, one can generally enjoy just one season only and that is summertime. The weather is constantly superb. The air temperature and the sea temperature are equal to about 3 degrees on this beautiful lush peninsula. Samana has an ideal climate for all kind of outdoor activities.
Samana has a semi-tropical maritime climate, with an average temperature of about 26°C for most of the year. This makes the peninsula in the Dominican Republic stunningly idyllic and perfect for a vacation— all-year round. Sunshine is also quite consistent throughout the whole year. The average number of sunshine hours per day ranges between 7 in December to 9 in April and from June to September.
In short; Samana, for sure one of the Dominican Republic’s greatest destinations, is a wonderful place for a sun-sand-and-sea vacation pretty much all-year round. All weather factors, from sunshine hours to air and water temperature, are amazingly constant. It appears that there’s just one variable, and that is the amount of rainfall. In general, December to March is the driest part of the year and August through to October mostly the wettest part.
From the conditions on land to those in the water, the weather throughout Samana is constantly superb. Never more than three degrees will separate the average air temperature from the average sea temperature in this beautiful resort, which results in an ideal climate for all outdoor activity.
The peninsula of Samana does have just one season whole year long and that is summertime. The average temperature is 26°C for most of the year. The climate on the peninsula is so called “semi-tropical maritime”. That is the reason why Samana is amazingly idyllic and perfect for having a beach holiday—all-year round.
Very little seasonal variation is the outcome of the typical coastal subtropical climate.
The rest of the Dominican Republic has a bigger discrepancy in the climate between winter and summer months. Samana has water on both sides of the peninsula. That is the reason the ocean moderates the fluctuations in temperature in Samana.
Samana’s motto truly is “365 days of sunshine”. Besides from very few summer sprinkles the skies are blue all year round and the temperature hovers around 27° Celsius.
Annual rainfall is therefore quite moderate on the Samana Peninsula, considering that it is a subtropical destination in the heart of the Caribbean.
Summertime, but then All-Year Long
The subtropical climate throughout entire Samana, with its ever-present trade winds and lukewarm water in the subtropical Atlantic Ocean, creates very enjoyable weather conditions all year long. There is just a few degrees’ difference in temperatures between winter months and summertime. Weather conditions in Samana are extremely stable throughout the whole year. The only exception is rainfall; there are apparently dry and wet periods.
From late November until half of April one can enjoy the best climatic conditions of the year.
Even for the duration of those casual winter days, when a “northeaster” gusts in from the North American continent, a simple long sleeve is more than enough extra clothing needed—and then just for the evenings—as average temperatures generally drop to a 24°C bare minimum.
It appears that January is the coolest month of the year with a 24°C average.
The warmest months of the year, end of May through to mid-October, have an average temperature of 27°C. That is only three degrees more than the annual minimum.
The mercury in the afternoons varies between 29°C and 31°C. This is throughout the entire year. Average low temperatures at night range from 19°C to 23°C. That is what we call very little variation.
In the middle of “winter” season, the temperature of the sea averages 27°C. This is extremely high by all accounts. In the water temperature, too, there is almost no great difference between the annual lows and highs. It is ranging between 26°C in February / March and 29°C from August through to mid-October.
The consistency of the sunshine is very reliable all the year. The average number of sunshine hours per day ranges between 7 in December to 9 in April. Due to its location, fairly close to the equator.
The Dominican Republic is located right in the heart of the Caribbean’s hurricane belt. Severe storms and hurricanes are uncommon in Samana. But August to November are considered the area’s hurricane months. Nowadays we have very advanced warning systems. Large gales pose little to no threat to the visitors of Samana. The course of most hurricanes results in their bypassing the Samana region.
If you happen to visit Samana in the more wet part of the year—the hurricane season—just be aware of it and keep an eye on the weather forecast. Most often, there is nothing to worry about in this particular corner in the Caribbean.
The risk of getting hit by a hurricane varies widely from one Caribbean island to another Caribbean island. Bermuda for example, like Miami too, has about a one-in-four annual risk of being affected by a hurricane; the odds for Nassau, Bahamas are about one-in-five.
But the islands of the southernmost Caribbean — such as Barbados, Curacao, Aruba, Bonaire, Grenada, and Trinidad and Tobago — rarely ever get hit by hurricanes: Bonaire, for example, has just a 2.2 percent annual risk of being affected by a hurricane. Your odds are about 50-1 against a storm interrupting your vacation. Likewise, the islands of the Western Caribbean are less likely to be affected by hurricanes than those of the Eastern Caribbean.
Hurricane history records show that Las Terrenas is a very safe place in the Caribbean as it has hardly ever been affected by hurricanes. Las Terrenas is possibly THE safest place in the Caribbean and even compared to Florida, Georgia, S&N Carolina it appears that Samana is a place that is hardly hurt by hurricanes.
During the major and devastating hurricane Irma in September 2017 we were in our home in Las Terrenas. The eye of Irma was just 100 km north of Las Terrenas. Sure, it was windy and there was a lot of rain. But that was nothing compared to the damage in St. Maarten, St. Barth or the Virgin Islands.
We do not know why that is. It could be luck of course. On the other hand, there is a natural protection by the mountains here. Or could it be some mysterious Taino energy… Who can tell? Its just a fact. In 2017, with devastating hurricane, Irma passing by Samana and Las Terrenas were not affected. Meanwhile destroying islands like St. Barth, St Martin, BVI and Florida like we have not seen before.
The driest months of the year are December through to March receiving respectively 71mm, 52mm, 31mm and 32mm of rainfall. Although there is no actual “rain season in Samana as there is in many other tropical climates, there are a number of months that receive a notably higher amount of rainfall. Mostly throughout the period from mid-May through to the end of November. However, the monthly rainfall totals should hardly ever exceed 152mm, which has been recorded in September. October is also one of more wet months with 140mm of rain. Annual rainfall is therefore quite moderate on the Samana Peninsula, considering that it is a subtropical destination in the heart of the Caribbean.
The increase in precipitation begins late August. This occurs when a seasonal change in the eastern Pacific Ocean weather conditions boosts the northeasterly flow of moisture across Central America right into the Caribbean area.
Mainly from the month of January until early March, chilly winds moving south from North America could bring in a couple of days of turbulent rainfall.
The effects of fronts like these, however, hardly last more than some days. In general, we can say that the summer is characterized by some afternoon thundershowers, which are mostly limited to the immediate area of Samana Bay and the western part of the peninsula.
Now let’s summarize this;
Samana truly is one of the greatest destinations in the Caribbean. It is a wonderful haven for a sun-sand-and-sea holiday all-year round. All the major weather factors, from sunshine to air and water temperature, are amazingly constant in Samana. The only variable, really, is the amount of rainfall. December through to March is the driest part of the year; August through to October the wettest part of the year. Travelers wanting to go scuba diving or snorkeling are advised to visit in the drier months, as underwater visibility is much better then.
