Sheffield weather: rain expected today, milder spell forecast later in the week
Sheffield faces a wet, cool day on September 17, 2026, though sources give slightly different rain probabilities; the wider UK saw an unusually warm, humid weekend but no heatwave is forecast.
A damp, cool day
Residents of Sheffield, in northern England, face cloudy and wet conditions today, September 17, 2026. The Times of India, citing UK Met Office data, reports light showers, with a high of around 15°C and a low near 9°C, averaging 12°C. Humidity is forecast to reach 97%, winds could gust up to 49.89 km/h, and the chance of rain is put at a very high 95%.
Sources do not fully agree on today's outlook, however. An earlier report published on September 16 had forecast "sunny intervals" for September 17, with a high of 15°C and a low of 8°C, rather than showers — a discrepancy likely explained by the forecast being refined closer to the day itself.
The preceding days
On September 15, Sheffield saw sunny intervals with an 80% chance of rain, a high of 17°C and a low of 11°C. Conditions turned wetter on September 16, with a 90% chance of rain, a high of 15°C, a low of 11°C, humidity of 92% and winds up to 38.62 km/h; sunrise was at 06:42 and sunset at 19:20.
Week ahead
The outlook points to a gradual improvement. After the wet start, September 18-19 should bring overcast or partly sunny conditions, and from September 19 temperatures could climb to 19-20°C with sunny intervals. Sources vary slightly on individual days — for September 21, one forecast points to mist with a high of 20°C, another to cloudy skies with a high of 19°C — but all agree the second half of the week will turn milder and sunnier.
Wider UK picture
BBC lead weather presenter Ben Rich notes that over the weekend much of the UK, including southern England, saw unusually warm and humid weather, with temperatures reaching 25-26°C in places, though nowhere met heatwave criteria, and cooler conditions returned by midweek. Typical mid-September temperatures in the UK range from 14°C in northern Scotland to 19°C in south-east England. According to the BBC, long-range forecasts currently show no clear signs of a heatwave later in September, although drier, higher-pressure spells are possible later in the month.
