Oldham Weather Forecast: Heatwave Continues Before Cooler Air Returns (25–28 June)

The latest Oldham Weather Forecast shows that the current heatwave is set to continue for a few more days before cooler and fresher air finally arrives towards the end of the weekend. High temperatures, tropical nights, and uncomfortable humidity will remain the main talking points through Thursday, Friday, and much of Saturday. While many people have enjoyed the recent sunshine, the combination of high temperatures and very humid air has made conditions feel much warmer than the actual thermometer readings. Forecast models also indicate an increasing chance of thunderstorms as the hot and unstable air begins to break down. Residents should continue taking precautions during the hottest part of the day, stay hydrated, and keep an eye on the latest weather updates as thunderstorms may develop with little warning.

According to the Oldham Weather Forecast, Thursday will be another exceptionally hot summer day with long spells of sunshine and only a small amount of fair-weather cloud developing during the afternoon. Temperatures could climb as high as 33°C in the warmest parts of the area, while a southeasterly breeze will make conditions feel even hotter. Overnight temperatures will remain unusually high, with many places staying above 20°C, creating another uncomfortable night for sleeping. As the evening progresses, the atmosphere is expected to become increasingly unstable, bringing the possibility of heavy thunderstorms later in the night.

Friday is likely to remain one of the hottest days of the forecast period. The day will begin warm and humid, with the possibility of a few early thundery showers before brighter skies return. During the afternoon, sunshine combined with rising humidity may once again trigger isolated thunderstorms, although many areas will remain dry. High temperatures between 31°C and 33°C are expected before slowly easing later in the evening. Winds will remain light to moderate, offering only limited relief from the heat. The Oldham Weather Forecast continues to highlight Friday as a day to monitor for rapidly changing weather conditions.

The weekend marks the gradual breakdown of the current heatwave, although Saturday will still feel very warm before cooler air finally arrives on Sunday.

Saturday

Saturday begins with warm and humid conditions, while sunshine and developing cloud create the potential for scattered thundery downpours during the afternoon. Not every location will experience thunderstorms, but where they do occur, they could bring heavy rain, frequent lightning, and brief gusty winds. Temperatures will remain between 24°C and 27°C, keeping many places comfortably warm despite the increasing cloud cover.

Sunday

Sunday brings a noticeable change in the weather as fresher Atlantic air moves across the region. Temperatures will fall back to around 21°C, accompanied by sunny spells, scattered showers, and a much more refreshing breeze. Some showers may still become heavy during the afternoon, but the lower humidity will make conditions feel significantly more comfortable. The Oldham Weather Forecast suggests Sunday will provide welcome relief after several days of hot and humid weather.

One of the biggest talking points during this forecast period is the increasing chance of thunderstorms. As hot, moisture-rich air becomes unstable, isolated thunderstorms could develop from Thursday evening onwards. Although it remains impossible to predict the exact locations several days in advance, some storms could produce heavy rainfall, lightning, hail, and sudden gusty winds. Residents are advised to stay informed by checking the latest weather warnings before making outdoor plans.

While air temperatures are expected to remain very high, humidity will continue to make conditions feel even more uncomfortable. Warm nights with temperatures above 20°C may make sleeping difficult, particularly in built-up areas where heat is retained overnight. Humidity levels are forecast to remain elevated until cooler air arrives on Sunday.

Beyond the weekend, the Oldham Weather Forecast indicates a return to more typical summer weather. Temperatures are expected to settle closer to seasonal averages during the first half of next week, with a mixture of sunshine and occasional showers. Early indications also suggest that more unsettled weather could develop as July begins, bringing increased cloud cover and a better chance of meaningful rainfall across the region.

The Oldham Weather Forecast continues to highlight another few days of hot, humid, and mostly dry weather before a noticeable change arrives during the weekend. Thursday and Friday are expected to be the hottest days, with the potential for isolated thunderstorms as the heatwave begins to break down. By Sunday, cooler temperatures, fresher air, and scattered showers will provide welcome relief, while next week is expected to return to more typical summer conditions.
