Scotland West Climate – July 2026 Update
City Coverage: Glasgow, Stirling, Ayr, Greenock, and Paisley
Summary
Scotland West enjoyed an exceptionally warm and sunny midsummer during July 2026, as dominant high-pressure weather patterns brought long stretches of clear skies and unseasonably mild conditions across the region. The sustained warmth capped off a May-to-July period that ranked among the warmest in over a century of meteorological monitoring, with higher-than-average temperatures forecast to continue through late summer.
This month in numbers
During July 2026, the regional mean temperature reached 15.2°C, standing 2.1°C above the 1961-1990 baseline to rank as the 8th warmest on record. Daily maximum temperatures averaged 19.4°C, representing a 2.5°C positive anomaly. Sunshine totals reached 206.9 hours, which is 55.2 hours above average and the 6th sunniest July in 117 years of records. Precipitation dropped to 82.5 mm, sitting 24.0 mm below normal, while zero frost days were registered.
What changed
The recent warmth extends a pronounced seasonal pattern. The 3-month season spanning May through July 2026 recorded a mean temperature of 13.03°C, standing 1.7°C above the 1961-1990 baseline to rank 4th highest in 127 years of records. Globally, land temperatures for the same three-month window were the 2nd highest on record, while July itself ranked 3rd globally at 15.8°C with a +1.6°C anomaly. Across the United Kingdom, July mean temperatures reached 17.47°C, which is 2.9°C above average. This sits within Scotland West's long-term warming trend of +1.17°C above baseline, following 2025 as the region's warmest year on record at 9.15°C.
What’s driving change?
The persistent summer warmth across Scotland West was largely anchored by that parked robust high-pressure ridges over the British Isles, blocking typical rain-bearing Atlantic lows. On a global scale, a moderate El Niño is currently active in the tropical Pacific, with ocean-atmosphere models indicating an 81% probability of it peaking at Very Strong in Oct-Dec. Tracked on our live monitor at ENSO, El Niño typically exerts a modest and historically inconsistent influence on northern European weather, but it reinforces the broader planetary warming trend that amplifies regional heatwaves.
Looking ahead
Seasonal forecasts from the Met Office suggest that high pressure is likely to remain influential, pointing to a higher probability of warmer-than-average conditions and extended dry spells continuing across the region through late summer and into autumn.

Shifting Seasons
Warm / cold seasonsKöppen Cfb · TemperateHow spring and autumn have shifted in Scotland West. Spring is defined as the date monthly temperatures first rise above the long-term annual mean (7.4°C, from 1900–1929); autumn is the date they fall back below it. Temperature swings 10.2°C peak-to-peak across the year - a classic four-seasons rhythm.

FAQs
FAQs
How is the climate in Scotland West changing?
Scotland West is warming in line with the rest of the world. The page above shows the latest monthly temperature anomaly versus the 1961-1990 baseline, the long-term annual trend, and the region's rank in the historical record. The headline panel also shows the long-term trend rate per decade and the warmest and coolest years on file.
What is the climate like in Scotland West?
Scotland West has a temperate climate (Köppen Cfb: Oceanic / temperate), with distinct warm summers and cool-to-cold winters. July is typically the warmest month, averaging 14.3°C, while January is the coldest at 3.6°C. Annual precipitation averages around 1779mm, spread fairly evenly across the year.
Where does the climate data for Scotland West come from?
Climate data for Scotland West comes from the UK Met Office HadUK-Grid (temperature, rainfall, sunshine, air frost), refreshed every month, when the upstream temperature and rainfall data are refreshed.
What is the climate baseline used on this page?
Anomalies on this page are calculated against the 1961-1990 climatological baseline, which is the standard reference period used by the Met Office, NOAA, IPCC and most national climate services. Some panels also show the source-native 1901-2000 (NOAA) or 1991-2020 (WMO) baselines for verification. See Methodology & Sources for the full reference.
Which areas does the Scotland West climate data cover?
The Scotland West climate profile covers Glasgow, Stirling, Ayr, Greenock and surrounding areas. Western Scotland climate data centred on Glasgow and the Clyde
How often is the Scotland West climate update refreshed?
The Scotland West climate update is refreshed monthly, typically a few days after the previous month closes and the upstream provider (Met Office HadUK-Grid, NOAA Climate at a Glance, Copernicus ERA5 or the Global Carbon Project) publishes its update. See the Climate Rankings for cross-region comparisons.
What counts as a Heatwave Day on the Scotland West climate page?
Heatwave Days use the Warm Spell Duration Index (WSDI) - the WMO/ETCCDI-standard heatwave measure: days that are part of a run of 6 or more consecutive days above the local 90th-percentile temperature for that calendar day. The 90th-percentile threshold varies by time of year (a hot day in January is judged differently to one in July) but is fixed to the 1961-1990 baseline for every year shown - it does not shift as the climate warms, which is why Heatwave Days trend upward over time.
Does the Scotland West climate page include frost and snow data?
Yes. Frost Days (days with a minimum temperature below 0°C, World Bank CCKP) and snow water-equivalent (GPCC) are shown alongside temperature and precipitation, each measured against the 1961-1990 baseline where a like-for-like historical comparison is available.
