quick_answer: Quick answer: Yes. Rain reduces speeds, lengthens braking distances and increases crashes, so the same route takes measurably longer in wet weather — and heavy rain can compound into much larger delays. Checking weather along your route before you leave, not just at your destination, is how you plan around it.

faqs[3]{q,a}:
  Does rain make traffic worse?,Yes. Rain lowers average speeds, lengthens braking distances and increases crash risk, while also pushing more people to drive — so the same route takes measurably longer in wet weather.
  How much longer does a commute take in the rain?,It varies by how heavy the rain is, the road, and whether it coincides with peak hours. Light rain may add only a few minutes; heavy rain during rush hour, especially if it causes a crash, can add far more.
  How do I check the weather along my route instead of just my destination?,Use a route-aware app. BoardSpy shows conditions along your whole route rather than at a single point, so you can see whether rain will hit the stretch you drive at the time you drive it.
