When to go
Cardiff is best to visit during late spring to early autumn as the warm weather adds to the city's pleasures and allows maximum experience of all the sites and areas of the city, although the city usually benefits from mild weather all year round, with notable exceptions.
Understand
Cardiff is on the south coast of the south Wales plain, with a shoreline on the Bristol Channel. Cardiff is quite a flat city, a characteristic that helped it become one of the world's leading ports for the transport of coal from the rugged south Wales Valleys.
