How Monsoon Season Leads to More Tempe Hydroplaning Accidents

August 06, 20254 min read

Every summer, Arizona drivers brace for monsoon season—a period marked by sudden, intense storms, heavy rainfall, and flash flooding. While these storms bring much-needed water to the desert, they also create hazardous road conditions, particularly in Tempe and other parts of the Phoenix metro area. One of the biggest risks is hydroplaning, when a vehicle’s tires lose traction on wet pavement.

The car accident lawyer near me team explains why hydroplaning accidents increase during monsoon season, how they happen, and what drivers can do to reduce their risk.


What Is Hydroplaning?

Hydroplaning occurs when a layer of water builds up between a vehicle’s tires and the road surface, causing the tires to lose contact with the pavement. When this happens, drivers can temporarily lose steering, braking, and control of the vehicle. Even experienced drivers can find themselves sliding or spinning out, sometimes without warning.


Why Monsoon Season Makes Hydroplaning More Common

Monsoon storms differ from ordinary rain showers. They often arrive quickly, dump heavy rainfall in a short period, and overwhelm drainage systems. This leads to:

Sudden Water Accumulation: Streets and freeways can flood within minutes. Low-lying areas, dips in roads, and intersections often collect water faster than drivers expect.

Oil and Debris on Roads: During dry months, oil and debris build up on pavement. The first heavy rains lift these slick residues, making roads even more slippery.

Variable Traffic Speeds: Some drivers slow dramatically in storms, while others maintain or even increase speed, creating unpredictable conditions that make collisions more likely when a vehicle hydroplanes.

In Tempe, with its network of busy arterials and freeway interchanges, these factors combine to make hydroplaning a recurring risk every summer.


How Speed and Tire Condition Contribute

Hydroplaning is more likely when a vehicle travels at higher speeds. Even new tires can lose grip on standing water if the driver is going too fast for conditions. Worn tires increase the risk significantly because they lack deep tread channels to move water away from the tire surface.

Many monsoon accidents occur when drivers fail to slow down or don’t realize that even moderate rainfall can create slick conditions, especially when hitting standing water at freeway speeds.


Common Types of Hydroplaning Accidents

Hydroplaning crashes often involve:

  • Single-Vehicle Loss of Control: A car spins or slides off the road after losing traction, sometimes striking barriers or roadside objects.

  • Rear-End Collisions: Drivers following too closely may slide into the back of another vehicle when braking on wet pavement.

  • Multi-Vehicle Pileups: On freeways, one hydroplaning vehicle can set off a chain reaction, especially during high-traffic periods common in Tempe’s urban corridors.

These accidents often result in injuries ranging from whiplash and broken bones to head trauma when vehicles spin out or roll over.


Liability in Hydroplaning Accidents

Drivers often assume weather-related crashes are “no one’s fault,” but Arizona law still expects drivers to adjust for conditions. This means:

  • If a driver was speeding in heavy rain or had bald tires, they may still be found at fault.

  • Following too closely in wet conditions can increase a driver’s share of liability in rear-end collisions.

Arizona’s pure comparative negligence system means fault can be shared. For example, one driver may be found 70% responsible for speeding on wet pavement, while another is 30% responsible for unsafe lane changes in the same storm.


Preventing Hydroplaning During Monsoon Season

While you can’t control the weather, you can reduce the risk of hydroplaning accidents:

  • Reduce Speed: Slowing down is the simplest and most effective way to maintain traction.

  • Check Tire Tread and Pressure: Properly inflated tires with good tread depth help channel water away from the tire surface.

  • Avoid Standing Water: Don’t drive through visible pools of water on roadways. Even shallow puddles can cause a loss of traction at speed.

  • Maintain a Safe Following Distance: Wet pavement increases stopping distance, making tailgating especially dangerous.

  • Brake and Accelerate Gently: Sudden maneuvers can increase the chance of sliding.

These steps help reduce the risk of losing control during Tempe’s stormy summer months.


Injuries From Hydroplaning Crashes

Hydroplaning accidents often cause severe injuries because vehicles may strike fixed objects or spin across multiple lanes. Common injuries include:

  • Whiplash and soft tissue injuries from sudden jolts

  • Broken bones from high-impact collisions

  • Head and brain injuries when vehicles roll over or occupants strike hard surfaces

These injuries can require long recovery times and costly medical care, increasing the stakes in insurance claims after a hydroplaning crash.


Why These Crashes Take Longer to Resolve

Hydroplaning accidents often lead to disputes about fault. Drivers may claim the accident was “unavoidable,” but insurance companies often examine factors like speed, following distance, and vehicle maintenance. Even when the weather is extreme, insurers typically consider whether the driver acted reasonably given the conditions.

As a result, hydroplaning claims can take longer to resolve, especially when multiple vehicles are involved.


Final Thoughts

Monsoon season is a part of life in Arizona, but its sudden downpours and flash floods make driving more dangerous. Hydroplaning accidents are common because heavy rain, oil buildup, and driver behaviors like speeding or following too closely combine to create a perfect storm of risk.

By slowing down, checking your tires, and avoiding standing water, you can reduce the chance of losing control during summer storms. Awareness and preparation are key to staying safe when the weather turns dangerous on Tempe’s roads.
