Extreme Rainfall in Portugal: Why Dry Zones Matter More Than Ever for Horse Health

A Changing Climate and Smarter Management

Portugal’s Wet Reality

Over the past seasons, Portugal has experienced repeated periods of intense rainfall, flooding and saturated soils. According to IPMA (Instituto Português do Mar e da Atmosfera), several regions including the Algarve, Alentejo and parts of Centro have recorded precipitation levels well above seasonal averages. Portuguese media such as RTP and Público have reported recurring flood events, damaged farmland and prolonged waterlogged ground conditions.

For horse owners, this is not just inconvenient weather.

It changes everything about management.

When paddocks are saturated for weeks, horses lose access to natural dry recovery zones. And that has direct physiological consequences.

What Constant Wet Ground Really Does to a Horse

1. Hoof Integrity Under Pressure

Prolonged moisture:

  • Softens the hoof wall
  • Weakens horn structure
  • Encourages bacterial growth
  • Increases risk of thrush and white line disease

Hoof horn requires periods of dryness to harden and stabilize. Without that, the microstructure of keratin weakens. Add anaerobic bacteria thriving in mud, and infections follow.

A horse standing 24/7 in wet conditions cannot physiologically recover hoof integrity.

Solution: Provide at least 6–8 hours daily on a genuinely dry surface.

2. Reduced Movement = Metabolic Stress

When paddocks are deep and unsafe, horses move less.

Less movement means:

  • Reduced circulation
  • Slower lymphatic drainage
  • Increased stiffness
  • Lower insulin sensitivity

Especially in sport horses, this combination can increase metabolic stress and muscle tightness.

Controlled hand walking, arena turnout, or structured light exercise becomes essential during heavy rain periods.

 

3. The Critical Role of Dry zones

Dry zones during extreme rainfall is not a step backward. It is strategic prevention.

A proper dry area:

  • Allows hooves to harden
  • Reduces bacterial pressure
  • Lowers thermal stress
  • Supports muscular recovery
  • Encourages horses to lie down (essential for REM sleep)

Bedding Matters

Prime Hay Shavings (wood shavings)

  • High absorbency
  • Lower ammonia build-up (when managed properly)
  • Comfortable resting surface

Rubber mats + adequate shavings layer

  • Most efficient moisture control
  • Reduces bedding waste
  • Maintains dry lying area

Minimum depth during wet seasons: 15–20 cm in resting zones.

A thin layer is cosmetic. It does not protect.

 

4. Respiratory Health in Wet Winters

Many assume rain improves air quality. Outdoors, yes.

But when horses spend more time inside:

  • Ammonia levels rise
  • Ventilation decreases
  • Dust accumulates

Chronic low-level airway irritation often begins in these conditions.

Good ventilation + dry bedding = non-negotiable.

 

5. Nutrition as Structural Support

Extreme rain also affects forage quality. Waterlogged fields can alter drying conditions and microbial stability.

A strong forage base remains the foundation. High-quality hay with controlled drying and storage such as Prime Hay helps stabilize gut health when environmental stress rises.

Targeted support products from brands like Cavalor and Pavo may assist in:

  • Hoof quality (biotin, zinc, methionine support)
  • Electrolyte balance
  • Gastric protection during increased stabling

But no supplement replaces dry infrastructure.

 

The Hard Truth

Climate patterns are shifting. Periods of extreme rainfall are becoming more frequent in southern Europe.

Relying purely on turnout during prolonged wet periods is no longer realistic management.

A dry stable is not a luxury.

It is preventive veterinary care.

Providing structured dry recovery time during extreme rainfall protects:

  • Hoof integrity
  • Tendon resilience
  • Immune function
  • Respiratory health
  • Performance longevity

In wet seasons, smart management separates short-term survival from long-term soundness.
