Oldham Weather Forecast: Very Warm Weather Builds with Heatwave Possible Over the Bank Holiday (21–25 May)
It’s a welcome change with the latest ”ldha’ Weather Forecast as temperatures start to rise after a relatively cool and unsettled start to May. With Bank Holiday weekend imminent, high pressure forms the main weather shape with more warm weather, more spells of sunshine and little rainfall all around the region. The highest temperatures will be in southern parts of the UK, with Oldham and much of the North West England also seeing an increase in temperature. Temperatures should still be slightly cooler at the coast thanks to onshore breezes, but inland they could reach the mid to upper 20s by the end of the weekend. Some areas in the region could reach the local heatwave definition temporarily if the temperature exceeds 25°C for a few days in a row, and there is increasing confidence on this possibility. This, however, will be influenced by the speed at which the warmer air moves up and how long it stays there. There is now a more positive outlook for outdoor pursuits during the Bank Holiday weekend as the weather looks sunnier after Thursday.

Weather Highlights
Thursday Oldham Weather Forecast
A band of rain will be moving across Oldham in the morning on Thursday, starting on a wet note. Heavy rain may occur for a time, but this should ease slowly with the rain moving eastwards during the afternoon. It will be followed by brighter skies, partly sunny with scattered cloud in the evening. There is a possibility of isolated showers, but after the rain has passed most will be dry. The Oldham Weather Forecast calls for temperatures of approximately 21°C, and fresh southwesterly winds with gusts of up to 20 mph are expected in the morning hours, making it feel colder. Clear skies will mean that the late part of the day will be warmer than the preceding nights.
Friday Oldham Weather Forecast
Friday will be a much more settled weather pattern. Following a bright start, there will be a lot of sun during the day with only a few breaks in the high cloud cover. The warmth will be enhanced, but easing southerly breezes will keep it comfortable. Friday will be one of the warmest days of the month with afternoon temperatures reaching 24°C. The Oldham Weather Forecast for today says it is very unlikely to rain, so it should be a great day to travel, venture out, and enjoy our local parks or countryside.
The transition from Thursday to Friday will be most prominent with a wet and unsettled morning followed by a much brighter and warmer day. Early morning temperatures will remain relatively cool, but will warm up rapidly with sun. With the dry weather, light cloud and gentle southerly breeze, it will be a good time to get outside to enjoy your plans. There should also be no major weather disturbance during the day, and visibility should be maintained for the majority of the day. Friday is one of the simplest days of the week to make plans for outdoor activities, if you are planning a longer trip or family outing.
Bank Holiday Weekend Outlook
The Bank Holiday weekend is set to bring some of the best weather yet this spring as continued sunshine and rising temperatures bring the weather into a new phase.
Saturday
Another dry and pleasant day with long periods of sunshine across Oldham on Saturday. The main part of the day will be dry, with a small amount of cloud developing in the afternoon, with a very slight chance of an isolated shower. Around 23°C and lighter winds will make the sunshine feel even warmer than the previous days. It will be a great day for markets, sports, get-togethers, and country hikes.

Sunday
It will be even warmer on Sunday with less cloud and plenty of sunshine from morning to evening. Temperatures are forecast to increase to near the official heatwave threshold for some regions near 25°C. Light winds and good sunshine will make it feel hot during the afternoon, with the evening to be pleasantly warm. Sunday may be one of the nicest days of the month, according to the Oldham Weather Forecast. These warmest temperatures will probably occur in the afternoon when the sun is most persistent. Those who are out for extended periods of time may want to plan for the warmer weather, especially in open areas. Although it will be warm, a slight breeze can help to keep it from being too hot to handle.
Bank Holiday Monday
Bank Holiday Monday is likely to be a clear, dry day with plenty of sunshine and warm conditions to be enjoyed. Highs will be up to **27°C** in the afternoon, which will be the warmest day of the forecast period. Light winds, low humidity, and no rain are expected. Everyone is looking forward to the perfect weather to enjoy a family picnic, visit local attractions, or just spend some time outdoors.
Would Oldham see a heat wave?
One of the main questions on everyone’s mind over the upcoming Bank Holiday weekend is whether Oldham will officially be in a heatwave or not. The forecast has been adjusted to show temperatures **25°C or above** on Sunday and/or Bank Holiday Monday. Sustaining the same weather pattern through the next few days may briefly put portions of the area into heatwave conditions locally. But this isn’t a sure bet yet, as a slight shift in the wind direction may bring a bit cooler temperatures during the day. The Oldham Weather Forecast will be keeping an eye on temperature trends and will be updated as more forecast information becomes available.
Sunshine and UV Levels
In skies that are becoming clearer over the weekend, sunshine will be much stronger than many have experienced over recent weeks. It will be a nice day, but UV will be high all day. If you will be outdoors for several hours, you need to remember to apply sun protection, drink fluids and take frequent breaks in the shade during the hot time of the day.
Looking Ahead
The immediate outlook, beyond the Bank Holiday, is for high pressure to be on the doorstep of the UK, with the weather remaining mostly dry and settled. Next week will be warm to start with, and heat wave conditions may persist until later in the week. Temperatures are expected to get closer to the low 20s as the wind turns to the east and then west. There are also a few isolated thundery showers later next week which might occur if humidity rises, but at present the rain seems unlikely to be widespread. The Oldham Weather Forecast remains for a mostly dry and warm finish to this month of May.
The pattern of weather which follows the Bank Holiday may then be favourable for some days to come, with temperatures expected to ease a little with time. There is some potential for slightly cooler air in more exposed locations in the overnight period if the wind changes direction. Conditions will remain comfortable even if daytime temperatures drop back into the low 20s, as in a more typical cooler spring spell. More humidity may be possible later in the week If the warmer air stays around. This may make it more likely that isolated thunderstorms will form in the afternoon or evening. These showers will, however, continue to be scattered in nature and not a continuous rain. Confidence in the forecast will increase as the week progresses, so people are urged to keep monitoring for any changes to the guidance.
Forecast Summary
As we move towards the Bank Holiday weekend, the Oldham Weather Forecast has all the ingredients for a major improvement in the weather. Once Thursday’s rain is over then there is a growing chance of dry and settled weather throughout the area with temperatures rising steadily, and many places getting dry weather for Monday. Confidence is high that Oldham will see one of its warmest periods of the month, with some uncertainty still remaining on whether official heatwave criteria will be met, so a great time to be outside. Overall, the most significant improvement is the one after Thursday morning, and a dry day with more and more sunshine will follow. Friday should be comfortable with the start of the warmer spell, with the highest temperatures on Sunday and Monday. While residents will benefit from the good weather, they should take sensible precautions to avoid the strong sunshine and high levels of UV.
