Old Basing is a village just east of Basingstoke in Hampshire, with the ruins of Basing House above the River Loddon and the Basingstoke Canal passing close by. Rain crossing the open Hampshire countryside reaches the village before it reaches the built-up streets of Basingstoke a short way west. Checking an Old Basing rain radar takes seconds, and hyperlocal radar shows which part of town the rain is actually crossing.
The open farmland around Old Basing gives an approaching shower a clear run from the south-west, and the Loddon valley collects the runoff quickly, so the village can be wet while Basingstoke, on slightly higher ground, stays dry a little longer. Frontal rain reaches the south coast up the English Channel from the south-west, and the Isle of Wight, the Downs and the coastline split bands as they move east. Warm sea in autumn adds energy to showers, which can build quickly along the shore while inland areas stay dry.
RainViewer's coverage of Old Basing, England, comes from Met Office radar, with the map updating on each new 5-minute scan. The live map shows whether a shower is still over the open farmland or already at Basing House, which a forecast for Old Basing cannot tell you.
Winter fronts cross the open farmland steadily, and the Loddon around Old Basing rises after a run of wet days. Atlantic depressions move along or across the Channel, and named storms bring strong winds and high seas along with heavy rain. Seafront roads, ferries and coastal paths feel it first, and rain on already-saturated ground raises the flood risk in low-lying areas.
Fronts lose their strength and cold showers cross the coast, occasionally with hail. Narrow, quick-moving showers make forecasting difficult, and it is seafront events and spring outdoor plans that are most exposed. Cold spring showers cross the countryside quickly, and walks around Basing House ruins are the plans most often cut short.
Warm land and a cooler sea trigger sea-breeze storms, and thunderstorms from the continent can drift in. Beach days, festivals and air shows depend on the cell track, because a storm can be over the seafront within minutes. Summer showers are short, and the towpath along the Basingstoke Canal depends on the gaps between them.
The ruins of Basing House stand in open grounds beside the Loddon with little shelter. Check the radar before setting out to explore the site.
The towpath along the Basingstoke Canal near Old Basing is fully exposed once a shower starts. Watch the cell approach and decide whether to start the walk.
The Loddon can rise quickly around Old Basing after heavy rain on the surrounding farmland. See whether the cell has passed before walking the bank.
The lanes between Old Basing and Basingstoke slow when heavy rain crosses the open farmland. See where the cell is and decide whether to set off or wait.
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 Old Basing the map also covers Basingstoke, Chineham and Odiham.
The ruins of Basing House stand in open grounds beside the Loddon with almost no shelter, and a shower crossing the farmland can reach the site within minutes. Visitors on the exposed walls and earthworks feel it first. RainViewer shows the shower crossing the countryside before it reaches Basing House.
Yes, heavy rain crossing the open farmland can flood the lanes between Old Basing and Basingstoke, and standing water builds fast on the low stretches. Check the radar before setting off. The map shows whether the cell is still ahead or has already cleared.
Yes, the River Loddon can rise quickly around Old Basing after heavy rain on the surrounding farmland, and the low ground near Basing House is the first to be affected. The village lanes shed water onto the fields nearby. The radar shows whether more rain is crossing the open countryside.
May to September is the best window to visit Old Basing, with Basing House, the Loddon and the canal towpath at their best. Showers are shorter in summer but can still catch the open farmland by surprise. Check the radar in the morning and plan outdoor time around the gap.
The Loddon valley around Basing House collects the runoff from an approaching shower first, while the canal towpath, set back on slightly higher ground, can stay dry a few minutes longer. A forecast covers both places with one number, while the radar map shows the rain crossing Basing House by the Loddon and missing the canal towpath a little further off.
The Old Basing radar in RainViewer uses Met Office data, updated every 5 minutes, to show precipitation as it falls rather than a modelled prediction. The Met Office C-band radars covering the south coast measure precipitation over the Channel as well as over land, so an approaching band is visible before it reaches the shore. That hyperlocal radar picture shows where a shower starts and stops, which a forecast cannot.
Set a rain alert on Basing House or the canal towpath and RainViewer warns you before rain arrives. That lets you time a visit to the ruins or a walk along the canal. The 2-hour forecast in 5-minute slices shows the next gap, and saved locations track Basingstoke and Odiham together.
A visit to Basing House and a walk along the canal towpath both depend on a dry gap, and RainViewer shows the next one.
Showers off the sea reach Old Basing with little notice, so timing matters more than the daily total.
Your weather app says rain in Old Basing this afternoon. RainViewer's live hyperlocal radar shows the cell still over the open farmland with Basing House still dry, and that decides whether the visit starts now.
