Local context

What to expect in September

Autumn in Trinidad is often underrated: 32°F, golden light and declining crowds. An interesting window. With 60% of rainy days, always have indoor alternatives planned. Not the best window, but acceptable if dates are constrained. January (9.6/10) is significantly better if possible.
