UK long range weather forecast
Monday will be dry and sunny for the majority, although with the continued risk of low cloud and fog around far west and northeastern coasts. A cloudier day for northwestern parts with strengthening winds and some rain here. Remaining very warm for most and hot in the southeast, with a small chance for some thundery showers here later on. Through the end of August and early September we will see a good deal of dry weather and sunshine. However, the north and northwest are likely to experience more unsettled periods with bands of rain followed by sunny spells and showers, with these conditions possibly spreading further south at times. Temperatures should be above average, most likely warm or very warm in the southeast, but nearer to average in the northwest.
Confidence remains rather low during this period. Southern areas are most likely to see the driest and sunniest weather in the early days of September, perhaps with some lingering wet and windy conditions affecting the north. However, longer spells of dry and sunny weather may occasionally develop across all parts. Temperatures are generally likely to be warmer than average, although there is little indication of anything exceptional at this time.
