Introduction
Wiper blades are easy to forget about in a climate where rain is infrequent — until the one storm of the season arrives and reveals blades that have been quietly degrading in the heat for months.
Why Wipers Wear Out Even Without Much Rain
The rubber edge of a wiper blade degrades from UV exposure and heat, not just from use. Sustained sun exposure common in this climate can dry out and crack the rubber over time, regardless of how often the wipers are actually used.
Signs a Blade Needs Replacing
Streaking, skipping, or a squeaking sound during use are the clearest signs. A visual check for cracking, splitting, or a blade edge that no longer sits flush against the glass also helps catch wear before the next time you actually need clear visibility.
Dust Buildup Compounds the Problem
Dust settling on the windshield between infrequent uses can combine with a worn blade to create smearing rather than a clean wipe, sometimes reducing visibility rather than restoring it. Keeping washer fluid topped up matters here, since a dry wipe over dust increases the chance of fine scratching on the glass.
Frequently Asked Questions
How often should wiper blades be replaced in a climate with infrequent rain? Roughly once a year is a reasonable guideline, since heat and UV exposure degrade the rubber regardless of actual usage frequency.
Why do my wipers streak even though they're not that old? Heat-related cracking can develop faster in this climate than the blade's age alone might suggest — a visual check is more reliable than assuming based on age.
Does dust on the windshield damage the glass over time? Wiping dust without adequate washer fluid can cause fine scratching, which is part of why keeping fluid topped up matters even when rain is rare.
