Morriston will see a mix of cloud and light showers through the day, with temperatures near the seasonal average. The live forecast above gives the detailed hour-by-hour outlook for this Swansea Valley area.
What is the typical weather pattern for Morriston?
Morriston sits in the Swansea Valley, a few miles north of the coast. This inland location means it tends to be a little cooler than coastal Swansea, especially on clear nights. Rainfall is spread fairly evenly across the year, though autumn and winter often bring the wettest spells. South-westerly winds are common, pushing Atlantic weather systems in from the Bristol Channel.
Will it be windy or foggy in Morriston today?
Wind speeds are generally moderate in the valley, but gusts can pick up when low pressure moves in from the west. Fog is most likely on autumn mornings after a clear, calm night. The live forecast above will show any fog alerts or wind warnings for the area.
Is Morriston often affected by coastal fog?
Not as much as the Swansea coastline itself. Morriston is a few miles inland, so sea fog tends to dissipate before reaching the valley. Radiation fog after clear nights is more common here, especially in autumn.
How reliable are the 7-day forecasts for Morriston?
Typically good for general trends, but day-to-day accuracy drops after day 4. The Met Office and BBC Weather both provide detailed outlooks for the area; checking the latest update each morning is wise.
