Ice on pavements, heavy rain, strong winds and morning thunderstorms — what you need to know before leaving the house with the kids.
Check this morning's school run weather →The school run window — typically 8–9am — is when pavement ice is at its most dangerous (before the sun has had time to melt overnight frost) and when morning rain can set the tone for the whole day.
| Condition | Impact | Action |
|---|---|---|
| Clear and dry, above 5°C | Ideal | Walk or cycle as normal. Light jacket sufficient. |
| Drizzle or light rain | Fine | Waterproof coats and school bag covers. Normal routes fine. |
| Heavy rain (5mm+/hr) | Unpleasant | Full waterproofs including trousers. Consider car or covered transport for long walks. Cycling not advisable for children. |
| Below 2°C (frost risk) | Ice risk | Treat all pavements as potentially icy. Walk slowly on shaded paths. Avoid shortcuts on grass. Wear boots, not smooth-soled shoes. |
| Below 0°C + overnight rain | Black ice likely | Significant ice risk on all pavements. Take extra care on slopes and shaded areas. Consider car. Cycling to school not safe for children. |
| Wind gusts above 40 mph | Danger for children | Young children (under 8) may be pushed off balance. Avoid routes past large trees or building sites. Consider car or covered transport. |
| Thunder/lightning | Stay inside | Do not walk or cycle in a thunderstorm. Wait indoors until 30 minutes after the last thunder. Call the school if you will be late. |
Ice is the biggest weather risk for walking to school in the UK. Unlike rain or wind, it is invisible (black ice) and falls are sudden and potentially serious — particularly for younger children and older adults walking them to school.
Ice forms when the temperature drops below 0°C and there is residual moisture on the surface — from overnight rain, dew, condensation or previous snowmelt. The classic UK black ice scenario occurs when: rain falls in the evening; temperatures drop to just above freezing overnight; then fall below 0°C in the early hours before dawn. The result is an invisible film of ice on all pavements, paths and roads by the time the school run begins. This typically occurs in the temperature range of -1°C to +1°C — not in heavy frosts where ice is more obvious.
Not all surfaces ice equally. The most hazardous surfaces during ice risk are: shaded pavements where the sun cannot reach to melt ice; metal surfaces — drain covers, bridge gratings, manhole covers; slopes and steps; wooden bridge decking; and black tarmac that has been wet overnight. Safe(r) surfaces include: gritted main roads (which are typically treated overnight); sunlit pavements by 9–10am on many days; and rougher, textured footpaths.
When ice is possible, teach children to: take shorter steps; keep weight centred; avoid carrying heavy bags on one shoulder (unbalancing); keep hands out of pockets (for balance and breaking a fall); and slow down on any slope. Wearing boots with textured soles rather than smooth-soled school shoes significantly reduces the risk of slipping.
UK school runs in autumn and winter frequently involve rain. The difference between a child arriving at school dry and miserable-all-day wet is almost entirely down to the quality of their waterproofing.
A genuinely waterproof coat (not a shower-resistant hooded sweatshirt) will keep children dry in all but very heavy rain. Look for coats with a taped-seam waterproof rating — not just a "water-resistant" finish that saturates after 10 minutes. For children who cycle or walk long distances, waterproof overtrousers are worth investing in — cold, wet trousers against the legs are the fastest route to an uncomfortable school day. Waterproof covers for school bags prevent homework arriving wet — particularly important for secondary school children with paper books.
Winter mornings often bring fog, which dramatically reduces visibility for drivers. On foggy mornings, ensure children wear or carry high-visibility elements — a reflective strip on a school bag, a bright jacket, or a clip-on flashing LED. Cycling in fog without lights is particularly dangerous; if a child's bike lights are not working, consider alternative transport on foggy mornings.
Children are more vulnerable to strong winds than adults — their lower weight and higher centre of gravity relative to their feet makes them easier to push off balance, and gusts that a parent would barely notice can be enough to knock a young child sideways.
On very windy days, avoid routes that pass large mature trees (risk of falling branches), construction sites (debris and materials can become airborne), and exposed crossings without shelter. In the aftermath of a storm, check for fallen branches or debris on the usual route before walking with children — large branches can fall across paths hours after the wind has passed.
Thunderstorms are most common in the UK during summer school months — late June, July and early September. They can develop quickly and can be severe, with heavy rain, hail, lightning and strong gusts all arriving within minutes of each other.
Never shelter under a tree during a thunderstorm — trees are frequently struck by lightning and the current travels down and outward through the roots and surface soil. Seek shelter in a solid building immediately. A car is also a safe refuge (not a convertible). If you cannot reach shelter and are in an open area, crouch low with feet together and hands over ears — do not lie flat and do not hold metal objects.
Wait at least 30 minutes after the last thunder before going outside again. Thunder can be heard from up to 10 miles away, so if you heard it, lightning was close enough to be dangerous. Count the seconds between lightning flash and thunder — divide by 3 to get kilometres, divide by 5 to get miles. At 3 miles (5km) or less, you should be taking shelter.
If a thunderstorm prevents you from leaving the house during the school run window, call or message the school to let them know. UK schools will not mark a child absent due to severe weather — they understand that parents keeping children safe at home is the correct decision. Simply check when the storm has passed and head in once it is safe to do so.
