You're probably thinking about a trip to the Caribbean and picturing 24/7 sunshine and a drink with a little umbrella. If you’re heading to the capital of T&T, that’s... mostly true. But honestly, Port of Spain Trinidad and Tobago weather is a bit of a weird beast compared to the rest of the islands. It’s not just "hot" or "rainy." It's specific.
Most people assume Trinidad and Tobago are basically the same weather-wise. They aren't. Port of Spain sits right against the Northern Range, and that mountain wall does some funny things to the clouds. You’ve got the sea on one side and mountains on the other, creating a microclimate that can go from "blistering sun" to "why am I standing in a river" in about six minutes.
The Two-Season Reality (No, There's No Winter)
Forget four seasons. We don't do that here. You’ve basically got the Dry Season and the Wet Season.
The Dry Season usually kicks off in January and hangs around until May. This is when the "Blue Skies" photos happen. You get these massive, steady northeasterly trade winds that keep things from feeling like a literal sauna. If you’re visiting for Carnival in February or March, you’re hitting the sweet spot. It's windy, it's bright, and the humidity actually takes a breather.
Then June hits.

The Wet Season is June to December. It’s not just a little rain; it’s the Inter-Tropical Convergence Zone (ITCZ) moving in. Basically, the atmosphere gets heavy. You’ll wake up to a gorgeous sunny morning, and by 2:00 PM, the sky turns charcoal. It dumps rain for an hour—I mean really dumps—and then the sun comes back out to steam everything dry.
That Weird Break: Petit Carême
Here’s something the travel brochures usually miss. Right in the middle of the rainy season, usually around September or October, we get this thing called Petit Carême.
It’s like a mini-summer. For a few weeks, the rain just stops. The winds die down, the sun gets intense, and it feels like the Dry Season came back for a surprise visit. It’s a local favorite, but man, it is hot. If you're in Port of Spain during Petit Carême, you’ll see everyone flocking to Maracas Beach to catch the breeze because the city streets start to feel like an oven.
Port of Spain Trinidad and Tobago Weather by the Numbers
I’m not a fan of boring charts, but if you’re packing a suitcase, you need the actual stats. Here is the breakdown of what it’s actually like on the ground:

- Hottest Months: April and May are usually the peak. Expect highs around 33°C (91°F). But with the humidity, the "real feel" is often closer to 38°C (100°F).
- Coolest Months: January and February. "Cool" is a relative term—we're talking 22°C (72°F) at night. Locals start wearing hoodies. You’ll think we’re crazy.
- Wettest Month: July usually takes the trophy. You can expect about 260mm of rain.
- Driest Month: March. It’s the peak of the dust season (more on that in a second).
The Sahara Dust Factor
Nobody tells you about the dust.
Every year, usually during the Dry Season, massive plumes of dust from the Sahara Desert blow across the Atlantic. It sounds cool, but it’s kinda annoying. It turns the sky a hazy gray-white and can trigger allergies for some folks. If you see a "dust haze" advisory on the local news, don't worry—it’s just the desert visiting the island. It does make for some incredible, deep-red sunsets, though.
The Hurricane "Safe Zone"
One of the biggest questions people ask is about hurricanes. Trinidad is technically south of the main hurricane belt.
While islands like Grenada or the Virgin Islands get hit regularly, Port of Spain usually just gets the "tail" of the systems. This means extra rain and maybe some gusty winds, but direct hits are extremely rare. The last major one was Flora back in 1963. Tobago, being further north, is slightly more at risk, but Port of Spain is generally considered a safe haven during the Atlantic hurricane season (June–November).

How to Not Look Like a Tourist
If you want to survive the Port of Spain weather, you have to dress for the humidity, not just the heat. Cotton is your best friend. Synthetics will make you sweat in places you didn't know could sweat.
Also, the sun here is "different." Since we’re so close to the equator (10 degrees north), you will burn in 15 minutes if you aren't careful. Wear the sunscreen even if it looks cloudy. Those clouds don't block the UV; they just act like a giant magnifying glass for the heat.
Practical Tips for Your Trip
- For Carnival (Feb/March): Bring a light windbreaker for the evenings and lots of hydration. It's the "dusty" time, so keep some eye drops handy.
- For Hiking (June-Nov): The Northern Range trails get muddy and slippery fast. If there’s a heavy downpour in the morning, maybe skip the hike to the bamboo cathedral or the waterfalls that afternoon. Flash floods are real.
- Traffic and Rain: In Port of Spain, rain equals traffic. If it starts pouring at 3:00 PM, don't plan on getting anywhere fast. The city’s drainage is old, and some streets can flood quickly, causing a total gridlock. Just stay where you are, grab a coffee, and wait it out.
Actionable Next Steps
If you are planning a trip right now, check the Trinidad and Tobago Meteorological Service website. They are surprisingly active and give great daily "color-coded" alerts for heat or rainfall. If you're coming for the beaches, aim for the January-to-May window to avoid the afternoon washouts. If you’re coming for the lush, green, "jungle" vibe, August is your month—just bring a sturdy umbrella that won't flip inside out when the wind picks up.
