What is the Arizona Monsoon Season?

The term “monsoon” describes a dramatic shift in wind and weather patterns. In Arizona, this seasonal shift happens when the jet stream moves, drawing moist air up from the south instead of the Pacific. This brings thunderstorms, sudden downpours, dust storms (commonly known as haboobs), and a rapid change in weather conditions.

When Does Monsoon Season Start in Arizona?

The Arizona monsoon season officially begins on June 15 and runs through September 30. During this time, Arizona experiences the majority of its annual rainfall, around 50-60%. Phoenix’s monsoon season baseline is 2.7 inches of precipitation, according to the National Weather Service (NWS). Most storms occur in July and August. In 2025, the season started right on time, and homeowners across Arizona are already preparing for what’s ahead.

Average Rainfall in Arizona: What to Expect in 2025

Actual rainfall amounts during monsoon season vary dramatically depending on location. Lower desert areas like Phoenix and the surrounding metro can expect an average of two to three inches of rainfall during the season. In contrast, mountain regions may see up to 16 inches.

Arizona Monsoon Season 2025 Forecast: Wetter and Hotter

Forecasts for 2025 show a slightly higher probability of above-average rainfall for most of the state, especially in the first half of the season. NOAA’s Climate Prediction Center has estimated a 43% chance of above-average precipitation, compared to a 24% chance of below-average precipitation. Regardless, mountain areas will most likely see the most rain during the season with up to 50 days of measurable rainfall. 

Climate experts anticipate the first half of the season to have the heaviest precipitation. Rainfall totals in July don’t necessarily predict the rest of the season. The actual influences are factors like the El Nino-Southern Oscillation, which is neutral in 2025. 

Homeowners should prepare for a range of scenarios, including drought conditions and heavy storms.

Most Common Home Damage During Monsoon Season

Every year, monsoon storms cause millions in property damage across Arizona. Knowing the risks helps homeowners take proactive steps before problems strike.

Common Types of Monsoon Damage

• Heavy Floods: Sudden rain can overwhelm drainage systems, leading to fast, dangerous flooding.
• High Winds: Monsoon storms bring strong winds that can tear off shingles, topple trees, and send debris flying.
• Roof Damage: High winds and rain are tough on roofing materials, making leaks common during monsoon storms.
• Broken Windows: Flying debris from wind gusts or hail can shatter windows in seconds.
• Mold and Biohazards: Standing water and humidity create the perfect environment for mold growth and other health hazards.

How to Prepare Your Home for Arizona Monsoon Season

Preparation is the key to minimizing storm damage and keeping your family safe. Here are the most important steps to take before, during, and after monsoon season.

1. Inspect and Maintain Your Roof

Make sure your roof is ready to withstand high winds and heavy rain. Replace broken or missing shingles, check for leaks, and clear out gutters and downspouts to allow water to flow freely away from your home.

2. Secure Windows and Doors

Install storm shutters or reinforce existing windows. Use weather stripping to prevent leaks. If you have older windows, consider upgrading to impact-resistant glass.

3. Landscape for Safety

Trim trees and bushes to prevent branches from falling on your home. Remove dead or loose vegetation. Clear out debris from your yard and secure outdoor furniture so it doesn’t become a hazard in high winds.

4. Prepare for Power Outages

Have a backup power source, such as a generator or battery packs for essentials. Charge devices and have flashlights and batteries ready. Stock up on bottled water, non-perishable food, and first-aid supplies.

5. Create an Emergency Plan

Discuss emergency plans with your family. Know where to go during a flood or storm warning. Keep important documents in a waterproof container, and store valuables on high shelves to avoid water damage.

What to Do After a Monsoon Storm

When the storm clouds clear, it can be tempting to relax and get back to normal life right away. However, the hours following a monsoon storm are critical for your safety and your home’s long-term protection. Here are the steps you should take as soon as it’s safe to go outside:

1. Inspect Your Home and Property

• Check for Roof and Structural Damage: Look for missing shingles, roof leaks, and any structural issues that could have developed during the storm.
• Examine Windows and Doors: Make sure there are no cracks or shattered glass. Even minor leaks or drafts should be fixed quickly to prevent further water intrusion.
• Walk the Perimeter: Look for downed power lines, damaged fences, and debris. Never touch electrical wires. Call your utility company or emergency services if you see hazards.

2. Address Flooding and Water Intrusion Immediately

If you notice standing water inside your home or garage, act quickly. Remove water with mops, towels, or a wet-dry vacuum if possible. Open windows and use fans to dry out affected areas. Mold can start growing within 24-48 hours, so it’s important to get treatment as quickly as possible.

If the flooding is severe, contact a professional at National First Response for emergency water damage clean up near you. Our trained technicians can remove water, dry your property, and prevent mold growth.

3. Document Any Damage for Insurance

Take clear photos and videos of all affected areas, including damaged personal items, before you begin any repairs or cleanup. This documentation will be valuable for insurance claims and can speed up the process if you need financial assistance.

4. Be Cautious with Utilities

If you suspect water has reached your electrical system or gas lines, do not attempt to restore power or use appliances until a professional has inspected your home. Turn off the main breaker and avoid standing in water near electrical outlets.

5. Prevent Future Damage

After you address immediate issues, take time to identify any weaknesses exposed by the storm. Update your emergency plan, improve landscaping for better drainage, or schedule roof repairs to prepare for the next monsoon event.
