The most important skill is not riding
Most weather skills are about riding better in difficult conditions. This article is about the opposite: recognising days when the sensible choice is to stay off the bike. Good riders skip rides, and doing so is not a failure of nerve. Some conditions carry risks that clothing, lights and careful handling cannot fully remove.
Decide before you leave
It is far easier to make a calm decision at home than on a road with the weather closing in. Check the forecast and any official weather warnings for your area before you go. If a warning covers your ride time, treat that as a strong reason to postpone. Warning systems and their wording differ between countries, so rely on your local weather service.
A simple habit is to set a personal rule beforehand: for example, “if there is a storm warning, I do not ride.” Rules made in advance are easier to follow than judgments made while you are keen to get out.
Thunderstorms and lightning
Lightning is a serious danger for anyone outdoors, and a rider on an open road is exposed. If thunderstorms are forecast, it is usually best to postpone. If you are caught out, general safety advice is to get into a substantial building or a hard-topped vehicle as soon as you can, rather than sheltering under a lone tree or staying on an exposed ridge. Rubber tyres do not make a bicycle safe in lightning.
Warning signs include darkening skies, a sudden drop in temperature, a change in wind, and distant thunder. Thunder means lightning is within range, so do not wait for it to get close before acting. Falling branches and flooded roads add further hazards during storms.
Heatwaves
Hot weather riding is manageable on a normal warm day, but a heatwave is different. High temperature combined with humidity and strong sun can lead to heat-related illness. Symptoms to watch for include headache, dizziness, nausea, unusual tiredness, confusion and an inability to sweat or cool down. If you feel any of these, stop in the shade, drink water and get help if you do not recover. This is general information rather than medical advice, and anyone with a health condition should ask a doctor about riding in extreme heat.
If you do ride in hot conditions, going early or late in the day, carrying plenty of fluid, choosing shaded routes and shortening the ride all help. On the hottest days, skipping the ride entirely is reasonable. Our separate article on riding in humid weather covers tropical conditions.
Ice and freezing conditions
Ice is among the hardest conditions to handle because grip can vanish without warning, including on roads that look merely wet. Black ice is hard to see, and shaded corners, bridges and early mornings after a cold night are common trouble spots. Riding on a sheet of ice is generally not something to attempt, and a fall at even low speed can cause serious injury. If temperatures are near or below freezing and surfaces are wet, consider postponing. For snow and ice riding in general, there is more detail in the winter article in this section.
Gales, flooding and wildfire smoke
Very strong winds make steering unpredictable and bring debris and falling branches. Flooded roads can hide potholes, drains and strong currents, so never ride through water when you cannot see what is underneath. Poor air quality from smoke or pollution can also make hard exercise unwise, particularly for people with breathing problems. In each case, follow local advice and err on the side of caution.
Warning signs to take seriously
- An official warning covering your route or time
- Conditions worse than forecast once you are out
- Surfaces you cannot judge, such as ice or floodwater
- You feel cold, wet and unable to stay warm, or overheated and unwell
- Visibility so poor that drivers may not see you
If you notice any of these, shorten the ride or head for shelter. Turning back early is nearly always better than pushing on.
Safer alternatives
You can still do something useful on days you skip the road:
- Ride a stationary trainer or use an indoor bike at a gym.
- Practise balance, slow-speed control or braking drills in a covered or garage space, using safe, flat, traffic-free ground.
- Do bike maintenance, such as a pre-ride bike check or chain cleaning, so you are ready when conditions improve.
- Rest, which is part of staying healthy and motivated.
If you get caught out
Weather sometimes turns faster than forecast. Move to shelter if you can, call someone if you need a lift, and walk the bike instead of riding on surfaces you do not trust. Carry a phone, a spare layer and some money for transport. Making that call early is not an overreaction. Outcomes in severe weather are uncertain, so choose caution.
