Wanderlust World Wanderlust World The UK's highest rainfall totals are consistently recorded on mountain summits in Scotland, Wales, and England, where orographic lift forces moist Atlantic air to rise, cool, and condense.
| Rank | Location | Region | Annual Rainfall (mm) | Annual Rainfall (inches) |
|---|---|---|---|---|
| 1 | St. Kilda (Hirta) | Scotland (Outer Hebrides) | 2,250 | 88.6 |
| 2 | Ben Nevis (summit) | Scotland (Grampians) | 2,055 | 81.0 |
| 3 | Scafell Pike (summit) | England (Lake District) | 1,925 | 75.8 |
| 4 | Snowdonia (summit area) | Wales (Eryri) | 1,850 | 72.8 |
| 5 | Dartmoor (high moor) | England (Devon) | 1,750 | 68.9 |
Note: These are high-elevation measuring points. Nearby towns (e.g., Fort William, Keswick, Betws-y-Coed, Princetown) receive significantly less but still high rainfall (1,500–2,500 mm). The wettest inhabited lowland areas are typically in the West Highlands (e.g., Glen Etive) and Lake District valleys.
