Heavy rain can arrive quickly on the Costa del Sol, especially in autumn and winter. A few dry months can make the first serious storm feel more dramatic, because gutters, drains and terraces have not been tested for a while.
Why the coast gets sudden rain
Warm Mediterranean water adds moisture to the air. When that air meets colder weather systems or is pushed up by the mountains behind the coast, the water vapour condenses and falls as rain.
Areas around Mijas and Fuengirola can feel this effect strongly because the Sierra de Mijas sits close to the sea.
What homeowners can check
Before heavy rain is forecast, it is worth checking:
- gutters and downpipes are clear
- terrace drains are not blocked by leaves or debris
- outdoor electrics are protected
- pool plant rooms are dry and ventilated
- air conditioning outdoor units are secure
- awnings, covers and loose furniture are tied down or brought inside
Electrical protection
Storms can bring power cuts and surges. Sensitive equipment such as air conditioning boards, pool controls, televisions and routers can be damaged by spikes in the supply.
If a property has had surge damage before, ask a registered electrician about protection at the consumer unit.
When to ask for help
Call an engineer if you notice water near electrics, repeated tripping, blocked drainage, gutter overflow or storm damage around air conditioning and pool equipment.
The best time to fix these issues is before the next heavy rain warning.
