What to wear to Trinidad Carnival: Port of Spain sits at 32°C (90°F) by day and 23°C (73°F) at night in February, on city streets, with a low chance of rain. That means loose natural fabrics and real sun protection, cushioned trainers or a low boot, and a bag small enough for the gate rules. The crowd leans carnival, costume and parade, so a full costume is the norm rather than the exception.
| Typical daytime high | 32°C (90°F) |

| Typical night low | 23°C (73°F) |
| Day–night swing | 9°C (16°F) |
| Rain risk | Low |
| Ground | Tarmac and pavement |
| Sun exposure | High, little natural shade |
At 32°C (90°F), synthetic fabrics stop breathing and anything tight becomes uncomfortable within an hour. Cotton, linen and loose cuts outperform whatever looks best in a photo, and SPF is part of the outfit, not an extra.
Everything below follows from those numbers.
