Weather in Cardiff

Best time to visit

Although Cardiff has much to offer all year around, most tourists head here in the summer when the weather is a little kinder. The Welsh climate may be notoriously unpredictable, but its annual celebrations help visitors see the city through rose-tinted glasses. St David’s Day on 1 March is a great time to wander the city parks when its national flower, the daffodil, begins to golden and bloom, while rugby is best caught during the damper, muddier months. Temperatures can rattle their way up to 25°C (77°F) in July and August but average as low as 2°C (36°F) in mid-winter.
