Huntingdon sits on the River Great Ouse in Cambridgeshire, facing Godmanchester across the water with Portholme Meadow, one of England's largest water meadows, spread out beside the river. Rain arrives from the west and the flat Ouse valley holds the runoff for days. This is where a Huntingdon rain radar earns its place. Hyperlocal weather radar shows the edge of each shower, which a city-wide forecast cannot.
Frontal bands arrive from the west after losing part of their moisture over England, and the North Sea adds showers on north-easterly winds. On the flat land nothing lifts the air, so rain tends to come as convective cells, which can drench one town and skip the next. The flat, wide Ouse valley gives rain nowhere to run off quickly, so Portholme Meadow beside the river can be waterlogged while the higher streets around the town centre stay dry through the same band.
For Huntingdon, England, RainViewer pulls live Met Office radar data straight onto the map, with a fresh scan roughly every 5 minutes. The live map shows whether a shower is still crossing the Ouse valley upstream or already over the town bridge, which a hyperlocal forecast for Huntingdon can track that a regional one cannot.
The heaviest rain of the year falls now, as summer thunderstorms hand off to the year's earliest autumn fronts across this otherwise dry region. Rivers rise, drainage strains and sea defences face their toughest test, while North Sea tidal surges add further flood risk along the coast. Winter rain on the Ouse catchment upstream fills Portholme Meadow for weeks, and the riverside path is the first thing closed by water.
Cold spring showers cross the flat valley quickly, and a walk over the town bridge to Godmanchester is the plan most often caught out. Heat builds over the flat land, and thunderstorms form fast and move slowly. Forecasts are least reliable because the storms are small, and show days and outdoor events are the most exposed.
Summer showers are short, and evenings on Portholme Meadow and the riverside path depend on the gaps between them. Rainfall eases off and becomes less frequent through these months, though frost, cold showers and North Sea drizzle still turn up on some days. It is the driest stretch of the year overall, but an easterly wind can still deliver showers and sleet.
Portholme Meadow floods easily after rain on the Ouse catchment upstream, and the paths across it are the first to disappear under water. Check the radar for rain building upstream before setting out.
The historic bridge linking Huntingdon to Godmanchester has open approaches on both banks, and a shower crossing the valley gives walkers little cover. Watch the cell approach and decide whether to cross now.
The A14 skirts the town close to the river, and standing water can build where it runs near the flood plain. Check the radar before setting off for the station or the road.
Hinchingbrooke's lake and woodland paths sit just west of town with little shelter away from the trees. A look at the radar shows how close the next shower is.
RainViewer shows UK precipitation using data from the Met Office, the national weather service, which runs a network of C-band dual-polarization weather radars. The Met Office network also feeds the European OPERA composite, and the RainViewer map refreshes with each new scan, about every 5 minutes. From Huntingdon the map also covers Godmanchester, St Ives and Peterborough.
Portholme Meadow is one of England's largest water meadows and floods readily after rain on the Ouse catchment upstream, so paths that were dry in the morning can be under water by afternoon. Walkers and anglers both watch the river level. RainViewer shows rain building upstream before the meadow floods.
Yes, the A14 close to Huntingdon can hold standing water where it runs near the Ouse flood plain after heavy rain, and spray builds fast in a downpour. A quick look at the radar helps before you join the road. The map makes clear whether the shower is still coming or has already cleared.
Yes, the River Great Ouse regularly floods Portholme Meadow and the lowest riverside paths after heavy rain on the catchment upstream, though the town centre on its slightly higher ground usually stays dry. The river can keep rising for a day or more after the rain stops. A look at the radar shows if more rain is falling upstream.
May to September is the best window to visit Huntingdon, with Portholme Meadow, the riverside path and the town bridge at their most pleasant and driest. Winter brings the highest flood risk on the meadow. Check the radar in the morning and plan the riverside walk around the gap.
Portholme Meadow sits low beside the Ouse and takes on water from rain that fell well upstream days earlier, while the town centre on higher ground can be perfectly dry at the same time. A forecast covers both places with one number, while the radar map shows the rain crossing Portholme Meadow and missing the town centre.
The Huntingdon 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 radar separates heavy convective rain from light frontal rain over the flat East Anglian countryside, and the North Sea coast is well covered. That live, hyperlocal feed is only as current as the last successful update.
Set a rain alert on Portholme Meadow or the town bridge and RainViewer warns you before rain arrives. That lets you time a hyperlocal walk or a commute. The 2-hour forecast in 5-minute slices shows the next gap, and saved locations track the meadow and the town centre together.
A walk across Portholme Meadow and over the town bridge both depend on a dry gap, and RainViewer shows the next one.
Weather in Huntingdon usually arrives from the west and south-west, with added showers off the North Sea to the north-east.
The forecast says rain in Huntingdon this afternoon. RainViewer's live hyperlocal radar shows the band still crossing the Ouse valley upstream with the town bridge still dry, which decides whether the riverside walk starts now.
