Months of data3
Per month261.3
Severity-weighted crimes per km² per month40.5 per km² per month
Search radius1.6 km

Recorded street-level crime within the search radius, weighted by offence type (violence and robbery x2, ASB x0.5), per km² per month, placed on a log scale from 1 (scores 100) to 300 (scores 0).

  • Counts recorded crime by location, not risk to any individual; busy city centres score lower because of footfall.
  • Locations are anonymised to nearby map points by the police.

Starts from the Environment Agency flood zone (Zone 1: 95, Zone 2: 60, Zone 3: 25), minus 10 if a flood warning area lies within 1 km (5 if only an alert area), minus 15 per active flood warning and 5 per active alert; a severe warning caps the score at 10.

  • Flood zones show the chance of river or sea flooding ignoring defences; they do not cover surface water or groundwater.
  • This is not a flood search. Use a professional search before buying.

Flood Zone 1 (low probability of flooding from rivers or the sea)

  • Flood alert: River Cole, Dorcan Brook and South Marston Brook

    High river levels today have led to flooding. Flooding is possible on Friday 23 October 2026. Flooding of low lying land and roads remains possible overnight, especially in areas of Swindon closest to the River Cole. Further heavy rainfall is forecast over the next 24 hours. River levels are sensitive to rainfall and are expected to rise again this evening in response to recent rainfall. We are checking rivers for blockages. We are closely monitoring the situation. Take care and avoid walking…

Flood zones show the chance of river or sea flooding ignoring defences. This is not a flood search; check the GOV.UK long-term flood risk service before buying.
