Seasonal Weather Patterns in Pasadena

Pasadena, California experiences a classic Mediterranean climate with warm, dry summers and mild, wet winters — a cycle that plays a major role in gutter wear, clogging, and home maintenance. In winter (December–February), the city sees most of its annual rainfall, often through strong Pacific storms that can quickly expose gutter blockages. Overflowing water can lead to roof edge leaks, fascia damage, or pooling around the foundation if gutters aren’t cleared beforehand. Spring (March–May) brings gentler showers and breezy days, but also heavy pollen and leaf debris from Pasadena’s abundant trees — especially oaks, camphors, and jacarandas. These materials can collect in gutters, causing early rust and restricting water flow just before summer’s dry heat sets in. By summer (June–August), Pasadena heats up significantly, with average highs in the 80s and 90s and almost no rainfall. While gutters stay dry, sun exposure, heat expansion, and airborne dust can weaken joints, seals, and coatings. The dry season also allows fine debris to settle into gutters, setting up blockages for when rain returns. In fall (September–November), the Santa Ana winds sweep through the foothills, scattering leaves, twigs, and dust across rooftops right before the winter rains arrive. Though Pasadena avoids snow and freezing conditions, its combination of heat, wind, and heavy winter downpours makes seasonal gutter cleaning and inspection essential to prevent clogs, leaks, and costly home repairs.

Best Pasadena Gutter Company Services

John and his beautiful and well trained dog came for estimate and he had some great suggestions on where to add and subtract the downspouts. We have never done seamless gutters and they really are very beautiful. We went with a beautiful dark bronze which matches the house and our fascia boards perfectly. The crew did a great job. We will see how they work after some rain but John let me know that they could come back if there is an issue and modify if necessary. Great warranty by the company. Honestly, the dog was the best part. She really should be on your business card not gutters!

I’ve helped many homeowners and property managers in Pasadena protect their homes from the effects of our local weather and tree-heavy neighborhoods. Pasadena gets around 20 inches of rain each year, mostly from November through April, with the heaviest storms often arriving in January and February. The long, dry summers bake leaves, dirt, and roof debris into gutters, while mature oak, pine, and eucalyptus trees shed heavily year-round. Add in the occasional Santa Ana winds that can fill gutters in a single afternoon, and it’s clear why seamless gutter systems and regular maintenance are vital to keeping Pasadena homes safe from leaks, overflow, and water damage throughout the year.
