Weather in Santo Domingo

Planning a trip to Santo Domingo? Here you will find the latest information on weather conditions, as well as detailed forecasts and visual charts to help you plan the perfect holiday.

The climate in Santo Domingo can be described as tropical trade-wind, which means warm weather all year round. Average annual temperatures fluctuate only slightly, remaining in a comfortable range from 24°C to 27°C. This makes the Dominican capital an attractive holiday destination at any time of the year, especially for those seeking sun and warmth.

There are no distinct seasons in the traditional sense here. Air temperature remains consistently high throughout the year. However, periods with slightly higher rainfall can be distinguished. According to data, the number of rainy days increases from May to November, peaking in July and August. At the same time, the total amount of precipitation remains quite low, suggesting that rains are likely short-lived and not prolonged. The "driest" months in terms of rainfall are January, February, and March.

Overall, the weather in Santo Domingo is predictable and pleasant. You can expect many sunny days, warm evenings, and a refreshing sea breeze. Even during periods with a higher number of "wet days", showers usually pass quickly, without interfering with your relaxation and exploration of this historic city.

In Santo Domingo, a truly tropical climate awaits you with warm temperatures throughout the year. The annual temperature range is quite narrow: average daily highs range from 28.1°C in January to 30.9°C in August, and average nightly lows range from 20.4°C in February to 23.9°C in August. The hottest months are generally July, August, and September, when the average temperature holds at around 27.2-27.4°C, with daytime heat in August reaching almost 31°C. The "coolest" months, if one can term them so for the tropics, are considered to be January and February with an average temperature of about 24.3°C and night-time values dropping to a pleasant 20.4°C.

Summer months in Santo Domingo, especially from June to September, are characterised by consistent heat. Daytime temperatures often rise above 30°C, and nights remain very warm, with temperatures rarely falling below 23.5°C. Humidity during this period can also be high, intensifying the sensation of heat. The winter period, from December to March, offers milder and more comfortable conditions. During the day, the temperature usually stays in a pleasant range of 28-29°C, while nights bring refreshing coolness with temperatures around 20-21°C. The temperature difference between day and night averages 7-8 degrees Celsius year-round, providing pleasant relief after a hot day, but without sudden cold spells, allowing you to enjoy evening strolls.

When planning a trip to Santo Domingo, it is important to understand the specifics of local rainfall. Although there is certain variability in the number of rainy days throughout the year, the total amount of precipitation remains quite low. This suggests that even during periods with frequent rains, they are likely to be in the nature of short-lived and not very intense showers or drizzle, rather than prolonged rains.

The highest number of "wet days" in Santo Domingo falls in the period from May to October. For example, in May there are on average 25 days with precipitation, in July up to 26 days, and in August 24 days. November also receives a noticeable amount of precipitation (about 4 mm), but the number of rainy days (on average 18) is already lower than in the peak months. In terms of rainfall volume, August is the "wettest" month, but even then only about 5 mm falls. This confirms that rains, although frequent during these months, are usually light and pass quickly, freshening the air but not seriously disrupting tourist plans.

The "driest" months, both in terms of precipitation amount and the number of rainy days, are January and December. In January, only about 1 mm of precipitation falls, and there are approximately 14 "wet days". February and March are also characterised by a small amount of precipitation (about 2 mm) and a relatively small number of days with rain (approximately 17 days). During these periods, the probability of encountering rainy weather is minimal, making them attractive for visiting.

When packing your suitcase for a trip to Santo Domingo, give preference to light and breathable clothing. Warm tropical weather prevails here throughout the year, so natural fabrics such as cotton and linen will be the most comfortable. Do not forget a swimsuit, even if you do not plan to spend all your time on the beach – cooling off in the hotel pool after a busy day will be very pleasant. Essential companions for your journey should be high SPF sunscreen, sunglasses, and a hat for protection against the strong sun.

Considering that the number of days with precipitation increases from May to November, although the total amount remains small, it would be prudent to take a light folding umbrella or a compact raincoat with you. Rains in Santo Domingo are usually short-lived and will not hinder your plans. For walking around the historic centre and sightseeing, you will need comfortable shoes – flat sandals or light trainers. In the evening, especially during the period from December to March, when the night temperature can drop to 20-21°C, or for visiting air-conditioned places, a light sweater, cardigan, or stole may come in handy.

Also, do not forget insect repellent, especially if you plan evening walks or trips to nature. Layering in clothing is not as critical here as in regions with sharp temperature changes, but having a light cover-up will allow you to feel comfortable in various situations. The main thing is that your clothes are comfortable and suitable for the warm, humid climate of the Dominican Republic.
