The average annual temperature is 25°C (77°F), and only fluctuates by about + or - 2°C, depending on the season.  The 'hottest' months of the year are from June to October, when temperatures during the day remain constant at around 29°C (84°F). In contrast, it's slightly cooler from December to March, with daily highs rising to around 27°C (80°F). At night temperatures drop by about 5°C, so that you rarely need more than just a sheet for covering to sleep comfortably at night.

 

Being in a tropical climate zone means constant humidity. But when you are along the shoreline, the cool breeze blowing in off the sea tends to make it feel less hot and more comfortable.

 

The precipitation varies considerably depending upon the time of year. The 'rainy season' here on the north coast typically begins in October and continues through the remainder of the year, but is usually over by early January. The rest of the year there are regular rains but they usually are brief tropical showers, quite heavy at times, and sunshine quickly follows.

 

In Las Terrenas it’s not uncommon to see rainfall and thunderstorms flashing offshore in the sea or behind the village in the mountains, while at the same time it remains completely dry on the beach. Or on other occasions we get brief 'sun-showers' with rain falling down on us while we're still in the bright sunshine, creating colorful rainbows. 

 

As you may know, hurricanes occasionally pass through the region, mainly from August to October. Fortunately Las Terrenas has never been in the direct path of any of these in recent history. On a few rare occasions it caught the edges of some powerful tropical storms, which meant that it was hit with heavy rainfall and strong gusts of wind for periods lasting no more than 2 to 3 days. Although the paths of hurricanes are unpredictable, based on the past record you can expect that it would be most unlikely for you to be caught in the middle of one while you're here.
