Weather in Port of Spain

Planning a trip to Port of Spain? Check out the current forecast and detailed charts below to prepare for your journey and know what to expect from the weather.

Port of Spain is located in a hot tropical climate zone, characterized by consistently high air temperatures throughout the year. It rarely gets cold here: average thermometer readings fluctuate in a comfortable range from 25°C to 28°C, making the city an attractive travel destination regardless of the calendar month.

The weather in the capital of Trinidad and Tobago is defined by two distinct periods. The first half of the year, particularly from January to May, constitutes the dry season. During this time, rainfall is minimal and there are many sunny days, which is ideal for beach holidays and sightseeing. April is statistically the driest month, when the probability of rain is reduced to a minimum.

The situation changes from June: the wet season begins and lasts until the end of the year. During the summer and autumn months, the number of rainy days increases significantly (up to 25–28 days per month); however, precipitation often falls in the form of intense but short-lived tropical downpours. Notably, warmth persists even during the rainy season, and September often becomes the hottest month of the year.

The temperature regime in Port of Spain is distinguished by enviable stability, making the city an attractive destination for travel at any time of year. The division into seasons typical of temperate latitudes is practically absent here: the weather remains warm and tropical year-round. The average annual temperature fluctuates in a comfortable range from 25°C to 27°C, creating ideal conditions for those seeking an endless summer.

According to statistics, the hottest month is September, when the average temperature reaches 27.6°C, and daytime highs can rise to 29.2°C. The summer period and early autumn (from May to October) are characterized by sustained heat, which may feel more intense due to the tropical climate. During this time, the air consistently warms up to 28–29°C, which is excellent for beach relaxation and water activities.

The winter months, especially January and February, bring only a slight "cooling," which can rather be described as pleasant freshness. During this period, the average temperature is about 25.7°C, making it the most comfortable time for long walks and excursions. It is worth noting that in Port of Spain, there is a minimal difference between day and night temperatures — the amplitude of fluctuations rarely exceeds 2–3 degrees. This means that even after sunset, the air remains warm (around 24–25°C), and you will hardly need warm clothing for evening promenades.

The climate of Port of Spain is characterized by pronounced seasonality of precipitation, which falls here exclusively as rain. The year can be roughly divided into two periods: a drier season in the first half of the year and a prolonged wet season that begins in summer. Travellers should take these features into account when planning outdoor activities, as the character of the weather changes substantially from month to month.

The rainy season usually starts in June, when the number of days with precipitation sharply increases to 25. The peak of humidity falls in July, which is the rainiest month of the year: precipitation can occur almost daily, up to 28 days in a month. A high frequency of rain (more than 21–26 days monthly) persists in August, September, October, and November, so in the second half of the year, an umbrella or raincoat will become your indispensable companions.

The most favourable time for those who prefer clear skies is the period from February to April. During these months, the probability of precipitation is minimal. The driest month is considered to be April, when only about 8 rainy days are recorded. February and March are also distinguished by stable weather (about 10 days with precipitation), making this time ideal for beach holidays and exploring the sights of the capital of Trinidad and Tobago.

Port of Spain delights travellers with warmth all year round, so the basis of your luggage should consist of light items made from natural breathable fabrics, such as cotton or linen. Given that the average air temperature holds steady around +26–27°C, you will need T-shirts, shorts, summer dresses, and open shoes. Do not forget swimwear and beachwear, even if the main purpose of your visit is urban tourism.

When planning a trip, it is important to consider the seasonality of rainfall. The period from June to December is characterized by high humidity and frequent rains, so a light raincoat, a compact umbrella, and quick-drying shoes will become essential companions. In the dry season (from January to May), there is significantly less precipitation, but the sun remains very active, so sunscreen with a high protection factor, a hat, and high-quality sunglasses are mandatory at any time of year.

For comfortable walks around the city, choose comfortable footwear, such as flat sandals or light trainers. It is also recommended to take one light long-sleeved cardigan or a stole: despite the heat outside, powerful air conditioning often operates in indoor spaces, shops, and transport, and the temperature difference can be noticeable.
