Met Office forecasts 31C with heatwave from this weekend that could last longer
North Wales is set to swelter today (Tuesday) as temperatures soar. Wrexham is forecast for a baking 31C this afternoon with other areas including Ruthin, Barmouth, St Asaph and Flint seeing 30C, by 4pm, according to the Met Office. The lowest relative temperature is Amlwch forecast for a still hot 25C.
It is the latest heatwave for North Wales - which is defined as temperatures of 25C and above, or the region, for three consecutive days. Other areas of the UK have different temperature thresholds.
Tomorrow (Wednesday), is also set to be another hot summer day with Wrexham again seeing temperatures of around 30C, alongside Ruthin, during the afternoon. The mercury will rise well above the heatwave threshold in the region's other areas too.
BBC weatherman Derek Brockway wrote on X last night (Monday): "Despite increasing cloud today, temperatures still reached 27°C in a few places in Wales. Hotter and humid air moves northwards and eastwards tomorrow into Wednesday. Highest so far this year is 33.1°C at Cardiff Bute Park on July 12th. August record 35.2°C at Hawarden 2/8/1990."
Looking forward it's also forecast to be another hot weekend, with the heatwave criteria again set to be met. Wrexham is forecast to be 26C at its hottest on Friday, Saturday and Sunday. With Barmouth also seeing 26C, 26C and 25C, respectively over that time.

Other areas will see similar temperatures, although they may dip below 25C at times, with Llandudno seeing 21C, 25C and 25C from Friday to Sunday.
And the hot weather looks set to continue for a time beyond the weekend. On Monday Wrexham is forecast for 25C in the afternoon, with other parts of North Wales seeing between 22C to 24C, with a similar story on Tuesday.
The Met Office long range forecast for the UK, from Saturday August 16 to Monday August 25, said: "High pressure is set to dominate the UK by this weekend, bringing fine, dry, and very warm or hot weather with light winds for most, though breezier in the far south.
"After a spell of cooler, cloudy, and murky conditions in the north, especially along coasts, it will turn clearer and warmer here too. Early next week, there's an increased chance of very hot conditions in the south, possibly with rain or thundery showers.
"Once this clears, changeable weather is more likely, with outbreaks of rain (most frequent in the west) and warm, dry interludes with sunny spells. Toward the end of this period, there are some indications of an increased chance of more generally unsettled weather developing, though confidence at this range is typically low."

Parts of England to hit 30C as fire crews travel across country to battle blaze
Parts of England will swelter through temperatures of up to 30C on Friday as firefighters grapple with a lack of resources amid the heatwave. The Met Office forecast patchy cloud across the north with some light rain and the odd shower in Scotland. Despite this, temperatures will remain warm, particularly across England and Wales. In London, highs of 30C are predicted, while Cardiff will only be slightly cooler at 29C. Further north, Belfast and Edinburgh are expected to be a little milder, with temperatures reaching 22C and 24C respectively. As the heat concentrates across southern and southwestern England, temperatures will climb to 30C in Salisbury and 29C in Cambridge, while central areas like Nottingham are also expected to see highs of 28C. It comes as firefighters travelled across the UK to help tackle the major wildfire at Holt Heath, Dorset, fuelling calls for increased firefighting resources. Ben Selby, Fire Brigades Union assistant general secretary said services had undergone '14 years of austerity'. 'The loss of 1 in 5 firefighter posts to cuts, with fire engines taken off the run and fire stations closed up and down the country, means that there is no resilience left,' he said. 'Wildfires are intensive incidents, requiring a large number of firefighters and specialist resources. They are becoming increasingly severe and frequent as a result of the climate emergency.' Dorset and Wiltshire Fire and Rescue estimated the blaze had burned through 72ha and would remain on the scene overnight. 'Crews are still working in three sectors dealing with an increase in flare-ups, hotspots and deep-seated fires identified using drones,' the statement read. 'This is due to the weather conditions.' Crews travelled from Merseyside, South Wales, Greater Manchester, Leicestershire, Surrey, Lincolnshire, Hampshire and the Isle of Wight, Avon, Essex and Kent among others, to assist local emergency services. Heat health alerts were extended into next week for much of England. Officials have said the country is suffering from 'nationally significant' water shortfalls. The national drought group, which includes the Met Office, regulators, government, water companies and other organisations, has met as five areas of the country remain in drought, with six more in prolonged dry weather status. The UK Health Security Agency said yellow warnings will remain in place for Yorkshire and Humber, the East and West Midlands, London and the South East, South West and east of England until 6pm on August 18. The weekend should be dry and sunny for most parts of the UK, with the mercury forecast to hover around 30C on Saturday and 29C on Sunday in south-west England.

Met Office says Tropical Storm Erin to affect UK weather for last weeks of August
Met Office says Tropical Storm Erin to affect UK weather for last weeks of August It looks to be an turbulent end to the summer for the UK It has been a relatively warm summer in Wales (Image: WalesOnline/Rob Browne) After what can be called an unusually warm British summer which has seen parts of Wales enter drought status the Met Office has indicated that Tropical Storm Erin could influence the UK's weather as August draws to a close. From Tuesday, August 19, to Thursday, August 28, current forecasts suggest that high pressure, which has contributed to the recent settled and warm conditions, will likely shift further north. This change may allow low-pressure systems from the Atlantic to move in bringing a greater chance of unsettled weather. Read the biggest stories in Wales first by signing up to our daily newsletter here . According to the Met Office there is an increasing likelihood of stronger winds and periods of rain, some of which could be heavy and thundery. Southern and western regions are expected to be most affected initially though these conditions may become more widespread as the period progresses. Despite the prospect of more volatile weather temperatures are forecast to remain above average with the potential for further hot spells, particularly in the south. Article continues below In light of this weather maps from Wednesday, August 20, to Friday, August 22, indicate that Wales can expect mostly cloudy conditions with occasional sunny spells. Temperatures on Wednesday will average around 21°C with highs of 23°C in Carmarthen. A long-range weather forecast suggests that Wales will be seeing mild temperatures at the end of August (Image: Met Office) A gradual cooling trend is expected over the following days with most areas across Wales settling at a comfortable 20°C on both the Thursday and Friday. However this is subject to change. People can look forward to mild weather towards the end of next week (Image: Met Office) A key factor in the forecast's uncertainty is the behaviour of Tropical Storm Erin, currently moving across the North Atlantic. According to the National Hurricane Centre (NHC) this is the fifth storm of the 2025 Atlantic hurricane season. The Met Office notes that systems like Erin are a common source of unpredictability in late summer forecasts and its path in the coming days could significantly shape the UK's weather pattern during this period.

Tropical Storm Erin: Met Office gives verdict on how UK weather will be impacted
Brits may have to pull out their rain coats and umbrellas later this month - despite being August - as a deadly storm over the Atlantic could have repercussions in the UK The UK could be set for some unseasonable weather thanks to a tropical storm making its way over the Atlantic. Storm Erin has so far swept across Cape Verde, where a state of emergency has been declared on the islands of São Vicente and Santo Antão after nine people were killed and around 1,500 forced to evacuate their homes. The National Hurricane Centre has warned people to be ready for the westward-moving winds that could reach the Leeward Islands, Bermuda or the east coast of the US. Now, the Met Office has suggested that the deadly storm could have a big say on weather conditions for us in the latter part of August. It comes as the Met Office tells Brits in 38 areas to prepare 'emergency' kit with three items. According to the forecaster's long-range predictions between Tuesday August 19 and Thursday 28, there is the likelihood of increased wind and rain on the horizon. This could turn thundery for southern and western parts of the UK. The Met Office explained: "The details during this period carry low confidence. High pressure will probably be increasingly displaced to the north through the first part of this period, allowing areas of low pressure to potentially make inroads from the Atlantic. This brings an increasing possibility of stronger winds and rain, some of which could be heavy and thundery, especially for southern and western areas, but this perhaps becoming more widespread with time. "Overall, temperatures look to remain above average, with the potential for some further hot spells, especially in the south. One of the determining factors of the forecast through this period will be the behaviour of what is currently Tropical Storm Erin as it progresses into the North Atlantic; this being a quite typical source of uncertainty in late summer." The forecaster further said in its blog posted today that weather predictions will become more vague from Monday due to what's happening across the Atlantic. It wrote: "Beyond Monday, the forecast becomes more uncertain, largely due to developments in the Atlantic. Tropical storm Erin is currently moving towards the United States, and its eventual path could influence UK weather. "It's not uncommon for tropical systems at this time of year to be picked up by the jet stream. Recent examples include Storm Floris and ex-tropical storm Dexter. The impact on the UK depends on where these systems sit relative to the jet stream, on the cooler, low-pressure side. "They can bring wet and windy weather; on the warmer, high-pressure side, they may remain offshore and contribute to warmer conditions. Sometimes the jet stream flows in a relatively straight path, much like a fast-moving river. "At other times, it meanders and loops, slowing down the movement of weather systems and making their paths less predictable. These meanders can lead to prolonged periods of wet or dry weather, depending on where the jet stream is positioned." Meanwhile, the UK has been hit with a couple of yellow weather warnings this evening as 11 areas have been told they might need to prepare an emergency kit. The Met Office issued the warnings for parts of Scotland and Northern Ireland and are expected to stay in place until 10pm. A warning was issued for the east of Scotland include these eight areas: Aberdeen, Aberdeenshire, Moray, Highland, Angus, Perth and Kinross, Fife, and Dundee. While the warnings in the east of Northern Ireland warning include: County Antrim, County Armagh and County Down. They have also been warned that flooding of homes and businesses could happen quickly in these locations, with damage to some buildings from floodwater, lightning strikes, hail or strong winds possible. The forecaster said: "There is a small chance of fast flowing or deep floodwater causing danger to life." It added: "Where flooding occurs, there is a chance of delays or cancellations to train and bus services." The warnings also suggest preparing an "emergency" flood kit with "torches and batteries, a mobile phone power pack and other essential items."
