Residents in Watford can expect a week of mild but changeable weather through 10 May 2026, according to the latest forecast from the Met Office. While temperatures are set to reach as high as 18°C, the week will bring varied conditions, including cooler temperatures mid-week and an increased chance of rain over the weekend.

Temperatures will hover between 13°C and 18°C throughout the coming days. Wednesday 6 May is expected to be the coolest day of the week, with a high of 13°C, though it may feel like just 10°C to those heading outdoors. Following a Bank Holiday weekend that brought unsettled conditions, the Met Office notes that this changeable pattern is set to continue.

Rain is a possibility throughout the week, with chances ranging from 10% to 40%. The weekend currently looks to be the wettest period, with a 40% chance of precipitation on Saturday and a 50% chance on Sunday at 1pm. Additionally, commuters should be aware that visibility on the morning of Sunday 10 May is expected to be poor, reaching only 2.1km.

On a positive note, allergy sufferers can expect relief as pollen levels are forecast to remain low all week. Air quality is also expected to stay low, meaning there are no pollution-related concerns for those planning outdoor activities. While UV levels will generally be moderate, the level is set to reach ‘High’ on Friday 8 May, and the Met Office advises residents to seek shade during midday hours, cover up, and wear sunscreen on that day.
