When to Plant Tomatoes in Port Angeles: Timing and Maturity Guide

Tomatoes are usually a practical fit in Port Angeles, though this is still a crop that rewards timely planting and sensible variety choice, especially among very early to mid-season varieties.

Typical Planting Window

Good fit in this climate

Use the planting dates below for tomatoes in Port Angeles.

Start indoors January 29
Typical planting window March 21 – March 31
Method Transplant
Typical days to maturity 75–85

Gardeners usually start indoors around January 29 and plant outdoors from about March 21. Most varieties need about 75–85 days to reach maturity once they are in the garden.

Tomatoes are generally practical in Port Angeles, especially when gardeners plant on time and stay close to very early to mid-season varieties.

Within Washington, Port Angeles usually reaches tomato planting time a little earlier than many comparable locations. That makes local site warmth more important than it would be where the seasonal margin is wider.

Best local strategy: Plant on time, use reliable varieties, and protect early growth so the crop keeps its margin.

Can Tomatoes Mature in Port Angeles?

Growing degree days measure how much useful warmth the season provides. For tomatoes, that warmth is what drives steady growth, fruit sizing, and ripening, so low GDD seasons often leave later varieties green or unfinished before frost.

Available GDD (base 50) 1289
Typical crop GDD target 1200
Heat margin +89

From the usual planting window, Port Angeles typically provides about 1289 growing degree days for tomatoes. With a typical crop target of 1200, that leaves a heat margin of +89. That heat margin usually gives the crop enough room to finish, but not so much that delays stop mattering. Timing and variety choice still affect how comfortably the crop fits.

If planting later than usual, this table shows how much growing degree day heat is still available from each point in the season. It is most useful for judging how much flexibility you still have before the crop starts losing margin.

Checkpoint Remaining GDD Heat margin Fit vs typical target
Apr 15 1289 +89 Usually fits
May 1 1287 +87 Usually fits
May 15 1255 +55 Usually fits

Best Tomato Varieties for Port Angeles

In Port Angeles, very early to mid-season tomato varieties are usually the best fit in a typical year. Slower choices can still work when gardeners want their specific qualities and do not give away margin through delay.

Varieties that often fit well here include:

Variety class Typical days to maturity Typical GDD need Local fit
Very early 55–70 850 Good fit
Early 65–75 1000 Good fit
Mid-season 75–85 1200 Workable
Late 85–100 1400 Poor fit

Main risk: This crop generally fits, but slower tomato varieties can run into trouble if planting is delayed or early growth stays cool and slow.

How Frost Affects Tomatoes 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

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

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

The usual trouble comes from delayed planting or from choosing slower varieties when the local season would reward simpler, faster choices.

In Port Angeles, the season is usually supportive for tomatoes, though warmer sites still help with how comfortably they finish before fall frost around November 19. Local gardens do not all warm and cool at the same pace. 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 tomatoes, warmer local sites often translate into earlier bloom, more reliable ripening, and less strain on the calendar.
