A pitted windshield in Paradise Valley calls for replacement when fixed pinpoints or deep wiper grooves cross the driver's view and scatter low sun or headlights after both surfaces are clean. Dirt moves or wipes away. Pits stay fixed, and blade scratches trace the wiper arc.
Inspect the glass while parked. Change the light angle and compare the driver's area with an outer passenger corner. That shows whether the marks interfere with the road, signals, driveway traffic, or the camera behind the mirror.
A broad pattern can look harmless in shade yet create windshield glare while driving into the sun.
Reading a Pitted Windshield in Paradise Valley
Pitting is a field of shallow cavities across the outer glass. Under low-angle light, those cavities become the tiny spots on a windshield that sparkle in the sun. A sandblasted windshield after a dust storm usually has a spread-out, peppered pattern rather than one obvious impact center.
Windshield wiper scratches have a different shape. They follow the blade sweep as curved lines or hazy bands. One hard grain can cut a narrow groove, while contaminated rubber can score a wider part of the swept area.
| Damage | Pattern | Result after cleaning |
|---|---|---|
| Pitting | Fixed pinpoints spread across an area | The pinpoints remain |
| Wiper scoring | Curved lines in the blade path | The grooves stay visible |
| Impact mark | A localized bruise, bullseye, or star | The impact center remains |
| Crack | A continuous line from an edge or impact | The line may branch |
| Residue | Film, smears, or irregular water spots | Its appearance changes during cleaning |
After rinsing away every loose grain, clean the inside and outside with nonabrasive products. View the glass from normal driver-eye height. Draw a clean fingernail lightly across one suspect arc; a catch confirms depth, although that test alone does not decide replacement.
Hail leaves a more localized impact pattern. National Weather Service guidance says golf ball-sized hail can occur during the monsoon, so a single bruise, bullseye, or star should not be grouped with a broad dust-pitted field. An impact point changes the decision because it can also be the start of a crack.
Pitting and cracking are separate problems, but the same windshield can have both. Phoenix's 1991–2020 normals average 111 days each year at or above 100°F, with an average first date of May 2 and last date of October 5. The same normals average 21 days at or above 110°F. A pit field paired with an impact or continuous crack deserves attention sooner than abrasion alone during a hot season this long.
An auto club spokesperson told FOX 10 Phoenix in 2017 that heat does not directly shatter windows but can worsen existing glass damage. Our explanation of Arizona heat and windshield stress cracks shows how to separate a crack from surface wear.

What the Dust Storm Does Before and After the Rain
The National Weather Service monsoon guidance defines the season as June 15 through September 30. It says haboobs are most common early in the season, can cut visibility to near zero in seconds, and may accompany thunderstorm wind gusts that almost always exceed 40 mph. Its direction for a driver caught in blowing dust is Pull Aside, Stay Alive.
The Phoenix metro event on August 25, 2025 shows how severe conditions can become. The NWS event summary reports visibility below one-quarter mile, near-zero visibility in places, and winds near 50–65 mph. Those regional measurements do not prove what caused a mark on one vehicle.
Windblown hard particles can strike the outer surface during the event. Afterward, grit remains along the lower glass, cowl, and blade edges. A short rain or washer spray may turn that deposit into slurry without flushing out every hard grain, and the first wiper passes can drag it through the swept area. Arizona haboob damage to a windshield can therefore include pitting, curved scoring, or both.
The town's 2022 General Plan says 8% of its housing is seasonal or used occasionally and that many owners do not occupy their homes year-round. A vehicle left parked through part of the monsoon collects grit on the windshield, blades, and cowl. Remove it before the first wiper stroke.
- Rinse first: Flush the windshield and lower cowl with clean water. Do not activate the wipers or wipe the glass with a dry towel.
- Clean the blade inserts: If the vehicle design allows the blades to be raised, wet-clean both sides of each rubber edge. Replace an insert that is torn, hardened, or still holds grit.
- Inspect after washing: Clean both glass surfaces, top up the washer reservoir, and lower clean blades onto clean glass. Then map the fixed pits, arcs, impacts, and cracks.
The General Plan says traffic grows in non-summer months as residents and tourists return, particularly on Lincoln Drive and Tatum Boulevard. That is also when the lower morning and late-afternoon sun can expose damage missed under summer shade. Check the glass when you return, before the first drive into low sun.
