While darker nights can make us feel less safe, surprisingly the research doesn’t show a simple across-the-board rise in crime during autumn and winter. Darkness is linked with some offences, including personal robbery and burglary, while several others peak in summer. The evidence supports sensible preparation, without assuming that every journey after sunset is dangerous.
Introduction
The walk home from work feels different. The evening jog just isn’t as enjoyable when the daylight has gone. As the evenings draw in, it’s reasonable to ask how much the risk has changed and how our personal safety is affected.
But are the winter months that much more dangerous? We look at the evidence, including where it challenges familiar warnings about darker nights.
Feeling unsafe deserves to be taken seriously
Feeling less comfortable after dark is common. In a 2022 survey across Great Britain, the Office for National Statistics found that people felt less safe walking alone after dark than during daylight in every setting studied. Women reported feeling less safe than men after dark, and disabled adults felt less safe than non-disabled adults.
The same survey found that people who had experienced harassment were more likely to feel unsafe in most settings. Concern about an evening journey is warranted, and not without evidence to support it.
However, a survey about how safe people feel does not measure how likely they are of being a victim of a crime. Perception, and crime statistics answer different questions and illustrate that the reality is more nuanced.
Darkness and winter are different questions
A study of darkness asks whether an offence is more likely at a particular time when it is dark than when it is light. A seasonal study asks whether more offences happen in one part of the year. Those comparisons can produce different answers.
Think about leaving work at 6pm. The clock time is the same in July and January, but the light, weather and number of people outside can differ. A rise or fall in monthly crime cannot tell us, on its own, which of those changes made the difference.
Researchers try to separate these influences by comparing particular hours or studying clock changes. That helps explain why evidence linking darkness to one offence does not establish that winter is more dangerous overall.
What the crime research found
Different offences peak at different times
A study published in 2023 examined London records from June 2013 to February 2020. Burglary and theft from the person peaked around November. Six of the twelve categories studied peaked in summer, including bicycle theft, antisocial behaviour and the combined category of violence and sexual offences. Robbery showed weak or unclear seasonality.
Geography matters too. A US government analysis of victimisation surveys from 1993 to 2010 found household burglary was generally highest in summer. Robbery did not show a consistent seasonal pattern. A finding from one country or city should not be treated as a rule for every neighbourhood.
Darkness can matter for particular offences
A 2025 study used South Yorkshire police records from 2010 to 2019 to compare selected hours in daylight and darkness, alongside control hours intended to account for seasonal changes. Its main analysis found higher occurrence after dark for bicycle theft, burglary, criminal damage, personal robbery and vehicle offences.
That is evidence worth taking seriously, yet the detail was less uniform; results varied between neighbourhoods, and additional analysis using different hours altered the findings. So while the study supports a link between darkness and certain crimes, it doesn’t provide evidence to support the notion that the darker nights are inherently more dangerous.
Evening daylight can affect robbery
US researchers Jennifer Doleac and Nicholas Sanders used daylight-saving clock changes to examine the effect of evening light. Their 2015 study covered 558 police jurisdictions using data from 2005 to 2008. After clocks moved forward in spring, daily robbery fell by approximately 7%, with a 27% reduction during the sunset hours affected by the change.
Because the clock change shifts daylight abruptly, this provides stronger evidence that light itself can influence robbery than a simple summer-versus-winter comparison. But the 27% figure concerns particular hours in that US study. It is not a measure of your chance of being attacked, or a percentage increase in all crime during winter.
What this means for your evening
These findings give us a more useful starting point than a general warning that assumes darker nights equal danger. Consider the place, the behaviour around you and the options available at that moment. Darkness is just one part of that picture.
An open station with staff nearby offers different options from a closed station with no one to ask for help. Someone repeatedly moving closer after you have moved away is more relevant to your next decision than the month on the calendar. You can respond to those details without needing to predict what will happen.
Crime totals also cannot tell you the likelihood of harm on a particular walk without information about how many people were there and for how long. These studies do not establish a current personal risk figure for someone travelling through Newport, Magor, Undy or Penarth.
Nor does mixed evidence mean you should ignore a concern or prove that you can handle a situation. You can change direction, go inside or ask for help whenever that seems the sensible choice. You do not need certainty about another person’s intentions to give yourself more space.
Practical preparation for darker nights
A little preparation can make an evening journey easier to manage.
- Plan your return journey.
Check when transport runs and where you could wait or ask for help if plans change. A route with useful lighting and open, staffed places may give you more options. - Travel and park in well-lit areas with plenty of human traffic.
The more people around you, the less likely it is that you can be singled out. The more people, the more witnesses, the greater chance a criminal can be positively identified. - Don’t take shortcuts
If the safer route is another 10 minutes on your journey, take it. Assess your route options and take the safest, not the most direct or quickest if they put you at greater risk. Don’t cut corners on your safety. - Stay connected
Make sure your phone is charged. Share your location with someone you trust who can see you location when you’re on your own. - If it feels wrong, trust your instincts
There’s probably a reason it feels off. Don’t apologise for prioritising. And don’t be embarrassed if you’re wrong. Be safe, not sorry. - Act. Don’t hesitate.
If you think you’re being followed, if something isn’t right, act on it. Seek safe harbour anywhere public that there are people. Get family, a friend or partner to meet you. Call the police if necessary. Don’t second guess yourself.
Common questions about darker nights
Are crime rates higher in autumn and winter?
Some offences show darker-months peaks, but there is no consistent increase across all crime types and places. London research found burglary peaking around November, while several categories like anti-social behaviour peaked in summer.
Does feeling unsafe mean I am overreacting?
A feeling alone cannot measure the risk, but you must take it seriously. Look at the situation and give yourself options. Moving somewhere you feel more comfortable does not require proof that someone intends to harm you.
Practice defensive skills that give you the best options
Defensive Training focused on improving your personal safety helps you set boundaries, learn situational awareness and sharpen spatial awareness. Confidence and practical capability develop through practice. While no training can guarantee what will happen in a real incident, training for such problems provides you with more options should the worst happen.
