Rain has returned to parts of the UK for the first time in several months, according to the Met Office, but forecasters are clear that the incoming showers will be highly variable and are not expected to resolve the wider drought conditions immediately.
What is expected
Early observations show the heaviest falls so far in central southern Lancashire with around 23mm recorded, and parts of Northern Ireland seeing approximately 13mm. Temperatures are set to ease across large areas on Thursday, following what was the fifth heatwave of the summer, when a peak of 38.1C was measured at Kew Gardens.
- The rain is forecast to be highly variable, arriving as broken showers rather than persistent, widespread downpours.
- Short, intense bursts are possible in places, with local differences in totals likely — some areas will see meaningful accumulations while others remain largely dry.
- Temperatures will fall below average in many regions for the time of year, but conditions will not immediately revert to long-term norms.
Practical consequences and water supplies
Although any rain will be welcome, organisers and water companies have emphasised that the showers will not instantly replenish depleted supplies. Wessex Water has announced its first hosepipe ban in half a century, affecting roughly 1.4 million customers in Bath, Somerset, Dorset and Wiltshire. Across England, more than 27 million people are now under some form of water restriction.
Thames Water has highlighted the precarious situation in the capital, reporting that London reservoir storage remains below expected levels at about 74 per cent capacity after an unusually dry July. That shortfall appears to be the result of very low rainfall in the month, despite recent reductions in household usage.
| Metric | Reported figure |
|---|---|
| Heaviest observed rainfall (central southern Lancashire) | 23mm |
| Rainfall observed in parts of Northern Ireland | 13mm |
| Peak temperature this summer (Kew Gardens) | 38.1C |
| Customers affected by Wessex Water hosepipe ban | 1.4 million |
| People in England under water restrictions | over 27 million |
| London reservoir storage (Thames Water) | 74 per cent |
What to do now
For most people the immediate change will be a drop in temperatures and the chance of showers that may be heavy for short periods. Practical steps to consider:
- Continue observing local water-use restrictions — hosepipe bans and other measures remain in force for millions and are unaffected by a few days of showers.
- Be prepared for sudden, brief heavy showers and possible localised flooding in poorly drained areas; keep an umbrella or waterproof handy and check local travel updates before setting out.
- If you manage gardens or vulnerable vegetation, bear in mind that variable showers will not guarantee sufficient deep soil moisture; continue to follow official guidance from local water companies and councils.
Confidence and outlook
Forecasters convey moderate confidence that the pattern of showery, uneven rainfall will continue in the short term. While this marks a meaningful break from weeks of dry weather, the amounts already recorded and those expected in the immediate run are not large enough to signal an end to the drought. Further, regional differences mean some communities will get significant benefit while others will see little change.
The coming days should bring a more autumnal feel in many places, with cooler daytime temperatures and a range of showers. Those dependent on water-saving measures should continue to plan on the basis that restrictions may be needed for some time.
Weather services and water companies will publish updated forecasts and reservoir figures over the next few days; monitor official communications for changes to bans, restrictions or flood warnings.
