Can Zucchini Mature in Port Angeles?

Growing degree days measure how much useful warmth the season provides. For warm-season crops like zucchini, GDD helps show whether local heat accumulation is usually strong enough for the crop to grow steadily and finish before fall.

Available GDD (base 50) 1289
Typical crop GDD target 750
Heat margin +539

From the usual planting window, Port Angeles typically provides about 1289 growing degree days for zucchini. With a typical crop target of 750, that leaves a heat margin of +539. That heat margin usually gives the crop a dependable buffer, so gardeners have some flexibility in planting date and variety choice without pushing the crop close to the edge.

Best Zucchini Varieties for Port Angeles

In Port Angeles, most zucchini varieties are usually realistic choices. Gardeners can often choose across the maturity range without giving up much day-to-day reliability.

Variety class Typical days to maturity Typical GDD need Local fit
Very early 45–48 675 Good fit
Early 48–52 750 Good fit
Mid-season 52–58 850 Good fit
Late 58–65 950 Good fit

How Frost Affects Zucchini in Port Angeles

Port Angeles usually has about 252 frost-free days, with a typical last spring frost around March 12 and a typical first fall frost around November 19.

Typical last spring frost March 12
Typical first fall frost November 19
Typical frost-free days 252
Minimum safe temperature 32°F / 0 °C

Zucchini is generally frost-tender and temperatures below about 32°F ( 0 °C) can slow growth or damage plants.

Zucchini is much more exposed to frost risk, so the frost dates matter as real planting boundaries rather than rough planning markers.

Problems here usually come from giving up part of the season through late planting, weak early growth, or slower variety choice than the crop really needs.

In Port Angeles, zucchini already has plenty of seasonal room when planted around March 19. In practical terms, the best spots are usually south-facing walls, sheltered gardens, raised beds, and sunnier urban lots. Cooler spots like low spots, exposed sites, and shadier yards are more likely to stay cooler and be less forgiving. For zucchini, warmer local sites usually help the crop get established earlier and grow a little more steadily.
