Before diving into preparations, let's understand what we're preparing for.

The Reality of Algarve Winters

Typical conditions (November-February):

• Average temperatures: 12-17°C

• Rainfall: 70-100mm per month (vs. less than 2mm in July-August)

• Occasional periods of unsettled weather with Atlantic storms

• Wind gusts during storms: typically 70-100 km/h (higher in exposed areas)

• Occasional hail and thunderstorms

What this means for your property:

While most winter days are mild and pleasant, storm events bring concentrated challenges. A single storm can dump a month's worth of rain in 24 hours, and wind can cause structural damage if your property isn't prepared.

When Heavy Rain and Storms Occur

The wettest conditions typically happen:

• October-November: Transition period, rainfall increasing significantly

• December: Peak of the rainy season (wettest month of the year)

• January-February: Continued wet weather, gradually decreasing towards spring

Critical insight: The first major rains after the dry summer often reveal problems that developed during the hot months—cracked roof tiles, damaged seals, and weakened structures suddenly become leaks and breaches.

The ideal time for these preparations is September to early October—before the first major rains arrive.

Roof and Exterior

Your roof is your first line of defense against winter weather. A small problem here becomes a big problem inside.

Roof Inspection

What to check:

• Tiles: Look for cracked, displaced, or missing tiles

• Ridges: Check ridge tiles are secure

• Valleys: Ensure water channels are clear

• Flashing: Inspect metal flashing around chimneys and vents

• Moss and debris: Remove growth that traps moisture

Why it matters: A single missing tile can allow water into your roof cavity, leading to ceiling damage, mold, and structural issues. What starts as a €20 tile replacement can become a €2,000+ repair if water enters.

DIY or professional? If you're comfortable on a ladder and have a single-story property, you can inspect from ground level and ladder access. For multi-story properties or if you see issues, hire a professional roofer. Expect to pay €80-150 for a professional inspection, with additional costs for any repairs needed.

Gutters and Downpipes

Essential tasks:

• Remove all leaves, pine needles, and debris

• Check gutters are securely attached to fascia boards

• Ensure downpipes flow freely

• Verify downpipes direct water AWAY from the foundation (at least 1.5 meters)

• Check for leaks at joints and seams

Why it matters: Clogged gutters overflow during storms, sending water down walls (causing damp and mold) or pooling near foundations (risking structural damage). We've seen foundation cracks develop from just one winter of poor drainage.

Exterior Walls

Check for:

• Cracks in render or stucco

• Damaged or missing sealant around windows and doors

• Peeling or blistered paint

• Signs of previous water damage

Action steps:

• Fill cracks with appropriate exterior filler

• Reseal windows and doors with weather-resistant sealant

• Touch up paint to protect underlying materials

• Consider full exterior painting if deteriorated (best done in autumn)

Algarve-specific note: Salt air from the coast accelerates exterior deterioration. Coastal properties need more frequent exterior maintenance than inland villas.

Outdoor Areas and Garden

Secure Loose Items

Wind speeds during storms can turn everyday items into projectiles.

Items to secure or store:

• Garden furniture (store in garage or tie down)

• Planters and pots (move to sheltered areas)

• Barbecue equipment

• Outdoor cushions and fabrics

• Garden decorations

• Children's toys

• Bins and recycling containers

• Satellite dishes (ensure securely mounted)

Tree and Vegetation Management

Essential tasks:

• Trim overhanging branches near the house, roof, or power lines

• Remove dead or diseased trees that could fall

• Cut back vegetation touching walls (traps moisture)

• Stake young or vulnerable trees

• Clear dead leaves and debris from around the property

Why it matters: Heavy rain saturates soil, making it easier for trees to uproot. Wind then does the rest. A falling branch through a roof is a worst-case scenario that's entirely preventable.

Professional help: For large trees or those near structures, hire a qualified tree surgeon. It's far cheaper than the damage a falling tree causes.

Drainage Systems

Check and clear:

• Drains and drain covers

• Drainage channels

• French drains (if applicable)

• Soakaways

• Overflow systems

Action required: Remove all debris, leaves, and mud. Test with a hose that water flows freely. Water should drain away from your property, not pool near foundations.

Red flag: If water regularly pools near your house, you may need to improve drainage before winter. This is a conversation for a local builder or landscaper.

Pool Area

Even if you close your pool for winter, preparation is essential.

Pool Preparation Options

Option 1: Keep pool operational (requires regular maintenance)

• Balance chemicals for cooler temperatures

• Reduce filtration time 

• Cover when not in use to reduce debris

• Monitor after storms for debris and chemical balance

Option 2: Winterize the pool

• Lower water level below skimmers

• Add winter chemicals

• Install winter cover

• Drain and store equipment as needed

• Remove and store pool accessories

Storm-specific considerations:

• Secure pool covers with proper fixings (wind can rip poor covers)

• Remove or secure pool furniture

• Check pool area drainage to prevent flooding

• Ensure automatic covers are functioning properly

Pool Equipment Protection

• Move sensitive equipment to covered areas

• Drain pumps and filters if winterizing

• Protect electrical connections from moisture

• Ensure equipment housing is weatherproof and secure

Interior Preparations

Even with a perfect exterior, some interior preparations protect your property.

Ventilation and Humidity Control

Essential steps:

• Install humidity monitors in key rooms (bathrooms, north-facing rooms)

• If property will be empty, leave interior doors slightly open for air circulation

• Consider a dehumidifier on a timer for particularly humid properties

• Ensure extractor fans are working properly

Why it matters: Cold, wet weather outside combined with a closed, empty property inside creates perfect conditions for mold. A €30 humidity monitor and a €100 dehumidifier can save thousands in mold remediation.

Heating System Preparation

Even if you won't be there, minimal heating prevents problems.

Action steps:

• Service boilers and heating systems in autumn (don't wait for winter)

• Test all radiators and heating zones

• Bleed radiators if needed

• Set heating to maintain minimum 15°C if property will be empty

• Ensure thermostats have fresh batteries

• Know how to restart system remotely or have someone local who can

Frost protection: While rare in the Algarve, occasional cold snaps can occur. Maintaining minimum heating protects pipes and reduces humidity.

Water System Protection

Check and prepare:

• Know where your main water shut-off is

• Inspect water heater for leaks or corrosion

• Check under all sinks for existing leaks

• Ensure washing machine and dishwasher hoses are in good condition

• Test all taps for proper operation

If leaving property empty for extended periods: Consider shutting off the main water supply and draining the system. This eliminates flood risk from leaks, though it requires proper procedure to avoid damage.

Security and Safety Systems

Storms create opportunities for problems and intruders.

Security System Checks

• Test all sensors and cameras

• Replace batteries in wireless components

• Ensure system has power backup

• Verify monitoring company has current contact details

• Test that you receive alerts properly

• Check outdoor cameras are weatherproofed

Storm-specific risks: Power outages during storms can disable security systems. Battery backup is essential for properties that will be unoccupied.

Emergency Lighting and Supplies

Even if you're not there, prepare for those who might need to access your property:

• Replace batteries in emergency torches

• Ensure circuit breaker box is accessible and labeled

• Keep basic tools accessible for emergency repairs

• Have emergency contact list posted visibly

For property managers: We maintain detailed property profiles including locations of all key systems, emergency contacts, and contractor networks, enabling us to respond rapidly and effectively to any storm-related issues.

Utility Management

Electricity

• Have electrical system inspected if it's been several years

• Ensure circuit breakers are labeled and functioning

• Consider surge protectors for valuable electronics

• Know how to reset tripped breakers (or ensure someone local does)

Storm risk: Lightning and power surges can damage electronics and trip breakers, shutting down security systems, refrigerators, and pumps.

Water and Drainage

• Know your water meter location and how to read it

• Check that storm drains near property are clear

• If you have a septic system, ensure it's pumped and serviced before winter

• Consider a water leak detection system (smart home technology)

Preparation isn't just about physical property—it's about having a plan when storms hit.

Build Your Emergency Contact Network

Essential contacts to have ready:

• Trusted neighbor or friend who can check property

• Local handyman for minor emergency repairs

• Plumber (for water emergencies)

• Electrician (for power issues)

• Roofer (for roof damage)

• Security company contact

• Insurance company emergency number

• Property manager (if you have one)

Remote Monitoring Options

Technology that helps:

• Smart home systems with humidity, temperature, and leak sensors

• Security cameras with remote access

• Smart thermostats you can control remotely

• Water leak detectors that alert your phone

Investment: Basic systems start around €200-300 and provide invaluable peace of mind.

Storm Monitoring

If you're abroad during winter:

• Subscribe to Algarve weather alerts

• Check Portuguese weather services (IPMA - Instituto Português do Mar e da Atmosfera)

• Join local Facebook groups for real-time updates

• Have someone local who can visit after severe storms

Once a storm passes, assess your property as soon as possible.

Immediate Exterior Inspection

• Walk the property perimeter looking for damage

• Check roof for visible issues (from ground level)

• Verify gutters and downpipes are still secure

• Look for pooling water that isn't draining

• Check for fallen branches or debris

• Assess fence and gate damage

Interior Assessment

• Check ceilings for water stains or drips

• Look in attics or roof spaces for leaks

• Test all electrical systems

• Run taps to ensure water systems functioning

• Check under sinks and around water heaters

• Document any damage with photos (for insurance)

When to Call Professionals

Call immediately if you notice:

• Active roof leaks

• Water pooling inside property

• Electrical issues or burning smells

• Structural damage (cracks, shifts)

• Significant tree damage threatening property

• Broken windows or doors

Time matters: Water damage worsens by the hour. Quick response prevents minor issues from becoming major problems.

If you won't be in Portugal during winter, additional planning is essential.

The 48-Hour Rule

After any significant storm (50mm+ rainfall or wind speeds over 70 km/h), someone should inspect your property within 48 hours. Here's why:

• Small leaks become big problems - What's a drip becomes a flood

• Temporary damage becomes permanent - Water stains set, mold starts

• Insurance requirements - Many policies require prompt damage reporting

• Security risks - Broken windows/doors need immediate securing

1. "It won't happen to me"

Every year, property owners assume their villa will be fine. Every year, unprepared properties suffer preventable damage.

2. Leaving preparation until the last minute

Contractors are busy in autumn. Book early or you'll be waiting until after the first storms—too late.

3. Ignoring small problems

That tiny crack or loose tile seems insignificant... until a storm turns it into a major issue.

4. Relying on neighbors alone

Neighbors are wonderful, but they have their own properties and lives. Don't make your property their responsibility without proper arrangements.
