About Cardiff weather

Cardiff is in Cardiff, United Kingdom at 51.48°, -3.18°. Right now it’s 9° and clear; today’s high is 12° with a 0% chance of rain.

The United Kingdom's weather is famously changeable, driven by its position at the meeting point of polar and tropical air masses in the North Atlantic. The Gulf Stream keeps temperatures milder than other regions at similar latitudes, but the constant battle between competing weather systems means forecasts can change rapidly. Maritime influences ensure that extremes are rare, but grey skies and drizzle are common companions.
