Residents of Welwyn Garden City are set for a week of warm and sunny weather, with temperatures expected to climb steadily from 19°C on Wednesday 20 May to a peak of 28°C over the weekend. According to the Met Office, the area will enjoy a mostly dry spell with the chance of rain remaining below 5% from Thursday 21 May through Tuesday 26 May.

While the forecast offers ideal conditions for outdoor plans during the upcoming Late May Bank Holiday, the local weather report indicates that ultraviolet levels will be high throughout the period. The national weather service advises residents to seek shade during the middle of the day, cover up, and wear sunscreen to stay safe in the sun.

Those planning to spend time outside should also be aware that pollen levels are expected to rise from low to moderate starting on Friday 22 May, which may affect hay fever sufferers. While the week will feel like a warm and fine contrast to recent days, Met Office Deputy Chief Forecaster Tony Wisson noted that conditions could become more unsettled later on Friday and into Saturday, with a chance of showers or thundery rain in some places.
