BBC monthly outlook
Wet and breezy at times in August but drier later
Wednesday 31 July – Sunday 4 August
Sunshine and showers. Warm later this week.
Wednesday will be breezy and showery in places with the showers heaviest and most widespread over northern England and Scotland. Some of the showers are likely to be thundery. Fewer showers further south with sunshine at times. On Thursday and Friday, most areas will have lighter winds. Many places will also have sunny intervals but showers are likely to develop again on both days although they should be lighter. The best of any lengthier periods of dry and sunny weather will be over western coasts and islands. This weekend, warmer and rather humid air is likely to drift in from the south with temperatures reaching the mid-20s Celsius in parts of the south. Saturday is expected to have the best of the sunshine. On Sunday, showery outbreaks of rain are likely to spread north-eastwards through the day, these perhaps becoming quite widespread later on.
Monday 5 August – Sunday 11 August
Turning wetter and breezier than normal for August
Next week may start dry and bright, at least for central, southern and eastern areas, thanks to a ridge of high pressure. However, it looks as though low pressure areas will then move in from the Atlantic. The track of these low pressure areas are likely to be further south than we might normally expect in August, bringing wetter conditions more widely than normal. Through the week, showers and bands of rain are likely to spread from the west at times, bringing above normal rainfall amounts to many for this time of year.
However, rainfall amounts in Scotland should be nearer normal. It is likely to become breezy at times, too, with brisk west or south-westerly winds. Despite the showers and rain, it should be rather warm with temperatures mostly near or slightly above the seasonal average. Most places will also see occasional drier and brighter interludes.
Monday 12 August – Sunday 25 August
Unsettled at first, then drier and warmer later
The middle part of August is likely to see a persistence of unsettled weather as further low pressure areas move in from the Atlantic at times. We might even see one or two ex-tropical storms reaching near our shores from the tropical Atlantic, bringing the potential for occasionally very wet and blustery weather, particularly in the west. Rainfall amounts are likely to remain above normal for August for most areas and it is expected to be breezy at times.
However, as we move into late August, there are some indications for drier weather to spread from the south. Central, southern and eastern areas of England could become much drier and warmer with the likelihood of a few hotter days. It should become calmer too. Further north and north-west, it may take longer for the rain to give way to drier conditions. However, it should at least become less wet than the preceding couple of weeks and a little warmer too.
August still looks like being a changeable month. We will take another look at the prospects for some drier and warmer weather later in the month.
