Rain in New Malden: What You Need to Know
New Malden sits between Kingston upon Thames and Wimbledon in south-west London, with Beverley Brook running along the edge of the town towards Richmond Park and the busy high street known for its Korean restaurants at the centre. Rain arrives from the south-west and the brook responds quickly. This is exactly what a New Malden rain radar is built for: hyperlocal radar follows the cell in real time instead of averaging it away.
What makes rain hard to predict here is not the frontal bands rolling in from the south-west, which are routine, but the convective storms that grow out of warm ground and city heat. The Chilterns and North Downs help direct where these cells form and travel, and a single storm can drop enough water to overwhelm drainage in minutes even after a forecast called only a chance of showers. Beverley Brook is a small, fast-responding stream, so heavy rain on the higher ground around Coombe and Wimbledon can raise it within an hour, catching the brookside path out well before the high street a short walk away notices anything.
RainViewer's map for New Malden, England, runs on Met Office radar, updating with each new scan so the rain shown is current, not modelled. The live hyperlocal map shows whether a shower is still over the higher ground to the south or already crossing Beverley Brook, which a forecast for New Malden cannot tell you.
Rain by Season in New Malden
Autumn and winter frontal season (October to January)
October to January is dominated by band after band of frontal rain, with named storms adding wind on top. As the rain keeps falling, the Thames and its tributaries rise, and it is the roads, railways and low-lying streets that feel the effects first. Winter rain on the higher ground upstream raises Beverley Brook quickly, and the path beside it is the first thing to flood.
Transition months (February to April)
Cold spring showers cross the area fast, and a walk along the brook towards Richmond Park is the plan most often caught out. Through February to April, cold showers, hail and sunny spells trade off quickly, and the small, fast-moving showers make this the hardest stretch of the year to forecast. Spring races, park events and weekend sport all carry the greatest exposure during this period.
Summer storm season (May to September)
Summer showers are short, and the high street and the park depend on the gaps between them. Heat builds over the built-up area and thunderstorms produce short, intense rain that floods roads and stations in minutes. Festivals, tennis and open-air events depend on the storm cell's track, which the radar shows before the sky changes.
Why You Need a Rain Radar in New Malden
Beverley Brook walkers
The path beside Beverley Brook has little shelter and the stream itself can rise quickly after rain on the higher ground nearby. A glance at the radar before setting out helps.
High street shoppers and diners
New Malden's high street empties fast once a shower moves in, and its restaurants and shops depend on the gaps between bands. A look at the radar shows how close the next one is.
Commuters on the A3 and at New Malden station
The A3 runs close to town and standing water can build fast in a heavy downpour. Check the radar before setting off for the station or the road.
Coombe Wood and Richmond Park walkers
Coombe Wood and the approach to Richmond Park sit on higher, more exposed ground above the town. Watch the cell approach on the map before setting out.

From New Malden the map also covers Kingston upon Thames, Worcester Park and Wimbledon.
New Malden Rain Radar: Frequently Asked Questions
- How does rain affect a walk along Beverley Brook near New Malden?
Beverley Brook is small and responds fast, so heavy rain on the higher ground around Coombe can raise the stream and soak the path beside it within an hour, often before the high street a short walk away feels anything. Dog walkers and joggers both watch the brook's level. RainViewer shows the shower crossing the higher ground before it reaches the brook.
- Does rain affect the A3 near New Malden?
Yes, the A3 near New Malden can see standing water and slower traffic in heavy rain, particularly where the road dips near the brook. Check the radar before pulling onto the road. The live map shows whether the shower is ahead of you or has already moved through.
- Does New Malden flood when it rains?
Yes, Beverley Brook can rise quickly after heavy rain on the higher ground nearby and spill onto the path beside it, though the high street on firmer ground usually stays dry. The brook drops again almost as fast once the rain eases. The radar shows whether the catchment upstream is still getting rain.
- When is the best time to visit New Malden to avoid rain?
May to September is the best window to visit New Malden, with Beverley Brook and the high street at their most pleasant. Spring can still bring quick showers off the higher ground. A look at the radar in the morning shows the walk's best gap.
- Why can it rain on Beverley Brook while the high street stays dry around New Malden?
Beverley Brook rises fast on rain falling over the higher ground to the south, so the path beside it can be flooded while the high street a short walk away stays completely dry. Live radar shows the edge of each cell, so checking Beverley Brook and the high street separately shows which side of the line you are on.
- Does the New Malden radar map work when I'm offline?
The New Malden radar map needs a connection to pull the latest Met Office scan, refreshed roughly every 5 minutes, so it is not built for offline use. Met Office dual-polarization radars separate heavy convective rain from lighter frontal rain, which matters here because the intense summer downpours are the ones that flood underpasses and stations. That live, hyperlocal feed is only as current as the last successful update.
- What can I do with RainViewer in New Malden beyond checking current rain?
Set a rain alert on Beverley Brook or the high street and RainViewer warns you before rain arrives. That lets you time a hyperlocal walk or a shopping trip. The 2-hour forecast in 5-minute slices shows the next gap, and saved locations track the brook and the high street together.
