Glasgow Weather: Heatwave Likely in Scotland This Week

After a slow start to summer, Scotland is finally getting its turn. A heatwave is likely across much of the country this week, with western areas — including Glasgow — set to enjoy the best of the sunshine and warmth. Meteorologist Sean Batty, writing for STV News on July 13, 2026, described the outlook as “absolutely glorious,” with conditions expected to last through the weekend and possibly beyond.

Forecast for Glasgow

For Glasgow residents, this means long spells of sunshine and temperatures climbing into the high 20s Celsius later in the week. The city sits squarely in the sunniest zone Batty identified: West & East Dunbartonshire, Renfrewshire & East Renfrewshire, Inverclyde, and Ayrshire are all listed among the places most likely to see uninterrupted blue skies. The Inner Hebrides, south and west Highlands, and Argyll & Bute round out the list of sun-drenched spots.

East vs. West Contrast

Not everyone will be so lucky. Parts of the north and east — including the Northern Isles, Caithness, Moray, Aberdeenshire, the Angus coast, East Fife, the East Lothian coast, and even Edinburgh at times — are likely to see low cloud and haar drifting in from the North Sea on an easterly breeze. That haar can keep temperatures noticeably lower and limit sunshine, creating a sharp contrast between the west and east coasts.

Batty noted that last week he predicted this could be Scotland’s best week of the year so far, and now it has arrived. After a mixed weekend with plenty of cloud, those who caught sunshine — particularly across the south and west — still enjoyed very warm temperatures. This week, that warmth spreads across much more of the country and sticks around for several days.

The BBC also reported the heatwave as likely, with a video segment published two days ago under the Scotland subsection. The broadcaster’s coverage included a note that more stories from around Scotland are available, though no specific travel or outdoor activity impacts were detailed in the provided sources.

Tips for Enjoying the Heatwave

For those planning outdoor activities in and around Glasgow, the forecast is encouraging. Long spells of sunshine and high-20s temperatures are ideal for park visits, cycling, or simply enjoying a pint in a beer garden. However, the lack of specific travel disruption information in the source material means readers should check local transport updates independently — especially if heading east, where the haar could reduce visibility on roads near the coast.

Scotland’s weather patterns often create microclimates, and this week is a textbook example. While Glasgow basks, Edinburgh may be shrouded in grey. The haar is a coastal fog that forms when warm air passes over the cooler North Sea, and it can persist for days if the wind direction holds. Batty’s forecast suggests the easterly breeze will keep the east coast cloudier at times, while western areas remain clear.

If you’re in Glasgow and looking to make the most of the heatwave, consider heading west toward the coast or into the hills for the best chance of uninterrupted sun. The sunniest places this week are all within easy reach: Ayrshire’s beaches, the Argyll coastline, or even a trip to the Inner Hebrides could offer a perfect escape.

As always, the heatwave forecast comes with a reminder to stay hydrated, use sun protection, and check on vulnerable neighbors. Scotland may not be used to prolonged high temperatures, but this week offers a rare chance to enjoy summer at its finest.
