Scotland has already had three separate heatwaves in 2026, most recently a mid-July spell in the Highlands and an amber extreme-heat warning across the south and east. As of 29 July 2026, that heat has passed: Scotland has cooled to the high teens and low 20s Celsius while England sits under its own fourth heatwave of the summer.
For much of Scotland, the Met Office counts a heatwave once daytime highs reach 25°C for three days in a row, a threshold well below the 28°C used in the hottest parts of England. This guide explains what a Scottish heatwave actually looks like, how hot it really gets, the national record, the current picture, and how to plan a summer trip around the heat.
If a warm spell has you thinking about a Scottish city break, you can compare flights to Edinburgh and flights to Glasgow, or browse hotels in Edinburgh and the wider United Kingdom. This piece is part of our broader coverage of the UK heatwave 2026 and the Europe heatwave 2026.
The current picture
As of 29 July 2026, Scotland is not in a heatwave and has no active heat-health alert. The country’s most recent hot spell peaked around 18-19 July, when an amber extreme-heat warning covered Edinburgh, the Lothians, Fife, Perth, Falkirk, eastern Lanarkshire, the Scottish Borders and Dumfries and Galloway, before cooler, wetter weather moved in from the north over the following days.
England, by contrast, is in the middle of its fourth heatwave of summer 2026, with amber heat-health alerts running from 28 to 30 July. Scotland sits outside that alert, with rain in the north and dry, milder conditions further south, and forecasters expecting temperatures to ease further into early August.
What counts as a heatwave in Scotland?
For most of Scotland, the heatwave threshold is 25°C on three consecutive days, a lower bar than in southern England. The Met Office defines a UK heatwave as at least three consecutive days on which the daily maximum temperature meets or exceeds a set threshold, and that threshold is not the same everywhere.
It is calculated from each county’s own summer climate, so cooler regions have a lower bar. The 25°C threshold applies across most of Scotland, Northern Ireland, much of northern England, Wales and south-west England, sitting below the 26°C to 28°C range used across central and south-east England.
Why the Scottish bar is lower
The thresholds reflect what is genuinely unusual for a place, which is why a run of 25°C days counts as a heatwave in Scotland but not in southern England. A run of 25°C days is far more of an outlier in Aberdeenshire than in Surrey, so it registers as a heatwave in one and not the other.
The current thresholds are based on the 1991 to 2020 climate averages, measured around the middle of summer. The practical takeaway for a visitor: a Scottish heatwave is real heat by local standards, in a country built for cool, damp weather rather than hot spells.
How hot does Scotland actually get?
Scotland’s all-time temperature record remains 34.8°C, recorded at Charterhall in the Scottish Borders on 19 July 2022, and it was not challenged during 2026’s heatwaves. That reading came during the same extreme heat event that pushed England past 40°C for the first time, and the Met Office confirmed it as the highest reliably measured temperature in Scottish history.
A higher reading of 35.1°C was reported that day at nearby Floors Castle in Kelso. The Met Office reviewed the site after the event and did not accept the figure as an official record, because the measuring location did not meet observing standards, so Charterhall’s 34.8°C stands as the official mark.
The record before 2022
The previous Scottish record was 32.9°C, set at Greycrook, also in the Borders, on 9 August 2003. The 2022 heat pushed the national ceiling up by almost two degrees in a single afternoon, which shows how exceptional that event was.
Warm summer days in Scotland more often top out in the low to mid 20s Celsius, and genuinely hot days in the high 20s or low 30s are rare and short-lived. Those hotter days usually favour the south and east, including the Borders and Aberdeenshire, over the cooler, wetter west coast.
Scotland’s three heatwaves of 2026
Scotland has recorded three separate heatwave spells so far in 2026, each falling well short of the national record.
- May 2026: Edinburgh reached 23.5°C on 25 May, in a UK-wide heatwave that peaked at 35.1°C in southern England.
- Late June 2026: Aberdeen’s Dyce reached around 29°C and Threave Gardens hit 31.2°C, Scotland’s hottest day of the year at that point, while no national record was broken.
- Mid-July 2026: The Wester Ross village of Achnagart recorded three consecutive days above the 25°C threshold, from 25.1°C to a peak of 28.3°C, with Kinlochewe and Dunstaffnage in Argyll and Bute also passing 26°C. An amber extreme-heat warning followed for parts of the south and east.
Edinburgh and Glasgow in the heat
Edinburgh and Glasgow feel hot spells acutely because both cities are dense, built of heat-holding stone, and short on shade and air conditioning.
Edinburgh
Edinburgh‘s highest recorded temperature is around 31°C, reached on 18 July 2022 during the same national heat event. In a hot spell the Old Town’s tenements and closes trap warmth, and open spaces like Princes Street Gardens and Arthur’s Seat offer little cover at midday.
If you are visiting, Edinburgh hotels with modern cooling are worth prioritising in July and August.
Glasgow
Glasgow‘s record high is 31.9°C, set on 28 June 2018, a day so hot that part of the roof of the city’s Science Centre reportedly melted. That broke a city record of 31.1°C that had stood since 1950.
For a summer stay, compare hotels in Glasgow and check whether cooling is provided.
Why Scottish heat can feel more severe than the number
A 28°C day in Scotland can feel harder to cope with than a hotter day in a Mediterranean city, and three things drive that.
Almost no air conditioning
Fewer than 5% of UK homes have air conditioning, and uptake in Scotland is lower still given the usually cool climate. Homes, older hotels, offices and public transport are frequently built without any active cooling, so there are fewer places to escape the heat indoors.
Homes built to hold heat in
Scottish housing is designed to keep warmth in through long, cold winters, and the same insulation and thick masonry that help in January trap heat in July. Temperatures build up inside over consecutive hot days and stay high overnight, which disrupts sleep and makes recovery harder.
Limited shade and acclimatisation
City centres offer limited shade, and neither residents nor visitors are acclimatised to sustained heat. The human body copes better with high temperatures it meets regularly, so in a place where hot days are unusual, the same reading lands harder.
Wildfire and water: what’s happening on the ground
The dry, warm spells of 2026 have driven two real, ongoing risks in Scotland: a major wildfire in the Cairngorms and worsening water scarcity in the east.
Cairngorms wildfire
Scotland declared a major wildfire incident in the Cairngorms National Park on 15 July 2026, which went on to burn an estimated 25 square kilometres of moorland and ancient Caledonian pinewood. It forced evacuations of Glenmore, Badaguish, the Cairngorm Mountain ski resort and nearby camping sites, with a later flare-up prompting evacuations in Nethy Bridge.
The Scottish Fire and Rescue Service had more than 70 firefighters, nine appliances and helicopter water-bombing support on scene, and as of 27 July the fire was reduced but not out, with smouldering ground fires still being tackled. Visitors should avoid affected areas of the national park and follow Scottish Fire and Rescue Service updates before planning a trip there.
Water scarcity in the east
Eastern Scotland has faced repeated dry spells through the summer, and SEPA’s monitoring shows conditions worsening rather than easing. As of late July 2026, catchments including the Tyne in Lothian, the Deveron, Almond, Firth of Forth, Firth of Tay, Don, Esk and Tweed were all at Moderate Scarcity, with parts of eastern Scotland recording under 10mm of rain for the whole month.
Several rivers, including the Tweed and its tributaries, are close to Significant Scarcity, the most serious level SEPA tracks. It rarely disrupts travel directly, but it is a useful signal of how dry the east has been, and residents and businesses in affected areas are asked to use water carefully.
Wildfire risk generally
Beyond the Cairngorms incident, Scotland’s moorland and grassland can dry out quickly in any prolonged warm spell, and the Scottish Fire and Rescue Service issues wildfire warnings during hot, dry periods, sometimes at “extreme” level. The advice during these alerts is to avoid open flames and barbecues outdoors.
This is separate from muirburn, the licensed, controlled burning of moorland, whose season runs from 15 September to 31 March under Scotland’s licensing scheme.
How to stay safe and cool
Public health guidance in Scotland comes from NHS inform, the Scottish Government and the Met Office, and the basics matter most when heat is unfamiliar.
- Drink water regularly, before you feel thirsty, and go easy on alcohol and caffeine.
- Stay out of direct sun between 11am and 3pm, the hottest part of the day.
- Keep your room cool: close curtains on sun-facing windows during the day, and open windows once the outside air is cooler in the evening.
- Wear light, loose clothing, a hat and sunscreen when you are out.
- Check on those most at risk: older people, young children, and anyone with a heart, breathing or serious health condition.
- Know the warning signs of heat exhaustion, such as headache, dizziness, heavy sweating and cramps. Move somewhere cool, rehydrate and rest. If someone is confused, stops sweating or loses consciousness, treat it as heatstroke and call 999.
When to go, and travel tips for hot spells
Scotland’s warmest months are June, July and August, with average city highs usually in the high teens to low 20s Celsius even in a summer with several heatwaves. Sustained heat is uncommon, so pack for changeable weather even in summer: layers, a light waterproof, and sun protection for the bright days.
Planning around the heat
If you are heat-sensitive, aim for late spring or early autumn, when days are mild and long without the peak-summer crowds. Book accommodation with fans or air conditioning if you are travelling in July or August.
Schedule outdoor sights like castles, coastlines and hill walks for the morning or late afternoon, and keep midday for indoor attractions such as museums and galleries. Trains and buses can get very warm in a heatwave, so carry water on longer journeys.
Before you fly, it is worth checking your flight’s live status, since extreme weather anywhere on the network, or ongoing wildfire response in the Highlands, can affect schedules and access to some areas.
Booking your trip: flights and hotels
Scotland is well connected to the Gulf and beyond, mainly through Edinburgh and Glasgow.
Flights
Compare flights to Edinburgh and flights to Glasgow, or search across the United Kingdom to weigh up nearby arrival points. Carriers serving Scotland include British Airways and easyJet, alongside long-haul options into the main UK hubs.
Hotels
For city stays, browse hotels in Edinburgh and hotels in Glasgow, or look more widely across hotels in the United Kingdom. In peak summer, filter for air conditioning if you want a reliable cool night’s sleep, since many older Scottish properties do not have it.
Frequently Asked Questions
What temperature is a heatwave in Scotland?
For most of Scotland it is 25°C or higher on three consecutive days. That is lower than the 26°C to 28°C thresholds used in central and south-east England, because the Met Office sets each area’s bar against its own climate.
What is the hottest temperature ever recorded in Scotland?
34.8°C, at Charterhall in the Scottish Borders on 19 July 2022. A higher 35.1°C reading at Floors Castle the same day was not accepted as an official record, and no heatwave in 2026 came close to it.
Is Scotland having a heatwave right now?
Not as of 29 July 2026. Scotland’s most recent heatwave and amber extreme-heat warning ran to around 19 July, and the country has since cooled while England sits under its own fourth heatwave of the summer.
Does Scotland get heatwaves?
Yes, though they are less frequent and less intense than further south. Because homes and cities are built for cool weather and rarely have air conditioning, the heat can feel stronger than the reading suggests.
When is the best time to visit Scotland to avoid extreme heat?
Late spring (May) and early autumn (September) bring mild, long days and a low chance of a heatwave. If you travel in July or August, book accommodation with cooling and plan outdoor activities for the cooler parts of the day.
