Rain changes the ride, not the rules
Riding in the rain is mostly the same skill set you already use, applied with more margin. Everything takes longer and grips less, and you are wetter and harder to see. Riders who handle rain well generally do so by slowing down a little, thinking earlier, and being comfortable enough that they are not distracted by being cold or soaked.
This guide is general information. If you are new to riding, practise wet-weather skills somewhere flat and quiet, and wear a well-fitting helmet.
Decide whether to go
Light or steady rain is manageable for most riders on a sound bike. Heavy downpours, thunderstorms, flooded roads and strong wind on top of rain are different, and postponing or switching to another way of travelling is often the sensible choice. If you do go, a shorter, familiar route on quieter roads is usually easier than a long unfamiliar one.
Dressing for it
You will probably get somewhat wet whatever you wear, so the aim is to stay warm and comfortable rather than perfectly dry.
- Outer layer: a waterproof, breathable jacket with a hood or collar that works under a helmet. Fully sealed fabrics can feel clammy when you work hard, so vents help.
- Base and mid layers: materials that stay warm when damp tend to be more comfortable than ones that go heavy and cold. Cotton usually does badly when wet.
- Hands and feet: these chill fastest. Waterproof or water-resistant gloves and shoe covers, or a spare dry pair of socks at your destination, make a large difference.
- Eyes: a clear or lightly tinted pair of glasses keeps spray out of your eyes. A cap under the helmet can help with drips from the brim.
If you need to arrive looking tidy, pack clothes in a waterproof bag and change at the other end.
Braking takes longer when it is wet
Water between tyre and road reduces grip, and on rim brakes the pads need a moment to clear water from the rim before they bite properly. Disc brakes are often less affected, but they still work with a tyre that grips less. Several things influence how far you travel before stopping, including your speed, the surface, the tyres and your loads, and the braking distance factors are worth understanding before you rely on any number.
In practice:
- Start slowing earlier than you would in the dry, and do it gradually.
- Use both brakes with smooth pressure rather than grabbing either one.
- On a long wet descent, brush the brakes lightly now and then so they stay effective.
- Leave a larger gap behind vehicles and other riders.
Do a quick brake test in a safe spot early in the ride so you know how the bike feels.
Being seen
Rain, spray and low light cut visibility for everyone, including drivers. Use bike lights front and rear even in daytime, with reflectors and some bright or reflective clothing. Drivers with wet windscreens and wipers going often notice you later than usual, so ride predictably, signal clearly and assume you have not been spotted. Check the batteries or charge before you set out, because wet rides are when lights matter most.
Slippery surfaces
Not every wet surface is equally slippery. Some of the worst are:
- Painted road markings such as arrows, zebra crossing stripes and bike symbols.
- Metal covers, including manhole and drain covers, and metal bridge plates or tram rails.
- Wet leaves, which in autumn can hide the surface and feel greasy.
- Wooden boards and smooth paving, which can be slick.
- The first rain after a dry spell, when oil and dust mix with the water on the road.
Try to cross these upright and in a straight line, without braking or turning on them. If you cannot avoid them, slow down beforehand. Learning to spot slippery surface clues such as a shiny sheen or a rainbow film on the road will help you plan earlier. Puddles can hide potholes or debris, so go around them when it is safe, or roll through slowly in a straight line.
Cornering and tyres
Lean less and take corners wider and slower than you would in the dry, with your braking finished before you start to turn. Smooth inputs are the theme: avoid sudden steering, sudden braking and sudden pedalling harder in a bend. Tyre condition matters too. Worn tyres or ones with small cuts can let you down in the wet, and it helps to understand tyre tread and grip in general terms. Follow the tyre manufacturer’s guidance on pressures, and ask a bike shop if you are unsure what suits your bike.
Keep your bike in mind
If your bike has no mudguards, expect a wet stripe up your back and a spray of water towards your face and drivetrain. Mudguards are one of the most useful upgrades for regular wet riding. Carry a few spares and basics because punctures are more common when there is debris washed onto the road.
After the ride
A few minutes of care helps the bike last.
- Wipe the frame, wheels and brake surfaces with a dry cloth.
- If it is muddy or gritty, a gentle rinse works better than letting grit dry on. Washing a bike gently, with a low-pressure rinse, is a sensible routine.
- Dry the chain, then re-lubricate it once it is dry. Chain cleaning is a short job that matters more after wet rides.
- Store the bike somewhere dry and not too warm, with the saddle and bar tape dried off.
- Dry your kit properly so it is ready for the next ride.
Follow the manufacturer’s instructions for your brakes, drivetrain and electronics, and take any brake or wheel concerns to a bike shop. Riding in rain is safe enough when you ride within your limits, but conditions vary and no preparation removes all risk.
