The wettest season is winter (December to February), with about 8.1 inches; the driest is summer (June to August), with 0.1.

When to clean gutters in Manhattan Beach

Frost is rare in Manhattan Beach, and in many years there is none (NOAA normals). With no hard freeze to strip the trees, the fall cleaning follows the leaf drop itself; book it once the trees over the roof are bare, and plan a second visit in spring.

When to clean gutters explains how the trees over a roof change the schedule.

Gutter and downspout size for Manhattan Beach rain

The short, hard downpour is what a gutter is sized for. In Manhattan Beach the five-minute rain expected about once in ten years falls at 3.20 inches an hour (NOAA Atlas 14 Volume 6). At that rate one 2-by-3-inch downspout drains about 2,250 square feet of roof and one 3-by-4-inch downspout about 4,500, by the rule in the Copper Development Association’s design handbook. Try your own roof in the gutter and downspout calculator, which starts from this figure.

Manhattan Beach is dry by national standards, about 12 inches in a normal year, but much of the rain that does come can arrive in short, hard storms: the five-minute downpour expected once in ten years still runs at 3.20 inches an hour. Where gutters are used here, the job is moving that burst away from the foundation, and keeping a dry season’s dust and debris from blocking the first storm.

The houses in Manhattan Beach

Half the homes in Manhattan Beach were built by 1970, 60% before 1980 (ACS 2020–2024). Houses that age have often had their gutters replaced once already; if not, the original runs and the boards behind them deserve a close look. On a house built before 1978, replacing more than 20 square feet of painted fascia or trim falls under the EPA’s lead-safe rule, so ask whether the crew is certified.

66% of households own their home, and 68% of homes are detached houses, 9% townhouses. If an association maintains the exterior, the gutters may be its job rather than yours; check before calling.

Hiring in California

Licensing for gutter work differs from state to state; ask a contractor in Manhattan Beach which license or registration they hold in California, and for proof of liability insurance. Hiring a gutter contractor

In California’s fire hazard severity zones, the 2025 Wildland-Urban Interface Code (in force January 1, 2026) requires gutters and downspouts of noncombustible material, and gutters fitted with an approved means to keep leaves and debris from collecting (section 504.4). (2025 California Wildland-Urban Interface Code, Chapter 5 (UpCodes))
