Port of Spain Weather in September

September weather

September feels hot, sticky and often cloudy in Port of Spain. The high is 30°C, with humidity at 81%, so walking around the city can feel tiring. Rain falls on 21 days, but showers don't necessarily spoil a whole day. You can still explore the National Museum and Art Gallery or stop for doubles, a curried chickpea snack, between showers.

The Queen's Park Savannah is pleasant when the weather clears, but muddy paths and heavy rain can make a long outdoor visit less appealing. Save hikes and other outdoor plans for a drier spell. September is also a poor month for beach plans compared with the drier months from February to April.

Republic Day

Republic Day falls on September 24. It's a public holiday, so you may find some businesses closed or running shorter hours. It's a good chance to see local celebrations, but don't expect the packed street-party scene of Carnival, which takes place earlier in the year.

Travelling with kids? Keep a rainy-day visit to the museum in mind, then head to the Savannah if the skies clear.

Quieter, wetter days

September sits in the wet season, so Port of Spain is generally quieter than during the popular February-to-April travel period. You may find less pressure on accommodation and tours, though prices vary. The trade-off is frequent rain and fewer reliably sunny hours for sightseeing.

For a practical rainy-day stop, the National Museum and Art Gallery is on Frederick Street, near downtown sights. You can duck inside when a shower hits instead of getting stuck outdoors. Check its opening hours before you go, especially around the Republic Day holiday.
