Port Angeles Planting Calendar

A practical guide to when planting usually works in Port Angeles. These windows are based on climate normals (not a forecast) and line up with the 50% last spring frost and typical early-season heat.

Beets	February 19 – March 5	direct sow	Detroit Dark Red	Excellent fit
Carrots	February 19 – March 5	direct sow	Bolero	Excellent fit
Lettuce	February 19 – March 5	direct sow / transplant	Buttercrunch	Excellent fit
Strawberries	February 19 – March 5	plant crowns / transplants	Seascape	Excellent fit
Onions	February 19 – March 5	sets / transplants	Redwing	Strong fit
Swiss Chard	February 20 – March 12	direct sow / transplant	Bright Lights	Excellent fit

Cabbage	February 26 – March 12	transplant	Stonehead	Excellent fit
Cauliflower	February 26 – March 12	transplant	Snow Crown	Excellent fit
Potatoes	February 26 – March 12	plant seed potatoes	Kennebec	Excellent fit
Main warm-season window Crops that usually do best once frost risk fades and the season starts opening up more fully.
Beans	March 12 – March 26	direct sow	Contender	Strong fit
Sweet Corn	March 17 – March 27	direct sow	Peaches and Cream	Good fit
Basil	March 21 – March 31	direct sow / transplant	Genovese	Strong fit
Cucumbers	March 21 – March 31	direct sow / transplant	Marketmore 76	Strong fit
Zucchini	March 21 – March 31	direct sow / transplant	Black Beauty	Strong fit
Melons	March 21 – March 31	direct sow / transplant	Hale's Best	Good fit
Tomatoes	March 21 – March 31	transplant	Early Girl	Good fit
Pumpkin	March 21 – March 31	direct sow / transplant	Small Sugar	Borderline
Watermelons	March 21 – March 31	direct sow / transplant	Sugar Baby	Borderline
Winter Squash	March 21 – March 31	direct sow / transplant	Delicata	Borderline
Peppers	March 28 – April 7	transplant	King of the North	Borderline

How to use this: aim for the earlier part of each window for the most reliable results. Later planting can still work, but it usually depends more on variety maturity, warmer microclimates, and simple protection like row cover or low tunnels.

Common Timing Mistakes

These patterns show up again and again in Port Angeles — especially in typical years.

Planting everything at once instead of staggering crops across the season.
Relying on calendar dates instead of crop maturity and typical frost timing.

Missed Your Planting Window? What Can You Still Grow?

This table shows what can still mature from several later-season planting dates in Port Angeles. It compares the growing degree days still typically available after each checkpoint with the heat each crop usually needs to finish, then applies a 15% safety margin to separate crops that usually still fit from ones that are more borderline.

Climate normals GDD planning

Compare your season’s typical heat accumulation against crop requirements before first fall frost.

Heat matters more than calendar days Use this when crop maturity depends on warmth, not just frost-free days. Especially useful for warm-season crops and short-season locations.

How the Growing Season Works in Port Angeles

Port Angeles usually has a relatively forgiving season, but results still depend on how quickly gardens warm in spring and how well crop choices match local conditions.

Stagger planting dates: spreading sowings and transplanting windows often works better than planting everything at once.
Fall planting is more realistic: many areas still have enough runway for a meaningful second round of faster crops.
Summer management becomes the limiter: water, fertility, and pest pressure often matter more than season length alone.

Remaining Season Heat in Port Angeles (Base 50 GDD)

Growing Degree Days (Base 50°F) measure heat accumulation. “Remaining GDD” shows how much usable heat is typically still available from a given date onward in a normal season.

Planting date	Base	Typical GDD still available
May 15	50	1255
June 1	50	1174
July 1	50	957
August 1	50	619

Use these values to judge whether a crop or variety still has enough heat left after planting. This is especially helpful for later sowings, shorter-maturity choices, and deciding whether a second round is realistic.

How Gardeners Adapt

Experienced gardeners in Port Angeles usually adjust their timing and crop choices to match how the season actually behaves, not just the calendar.

Using row cover or low tunnels to smooth out temperature swings early and late in the season.
Succession planting fast crops to keep beds productive through summer.
Watching local conditions closely and adjusting timing year by year.

Port Angeles Garden Planning Chart

A practical “typical year” for planning. Use it as a baseline, then adjust for microclimates and variety maturity.

Stage	What it usually means
Early season	Start cold-tolerant crops, prep beds, and pay more attention to soil warmth and night temperatures than to the calendar alone.
Main planting	Around March 12, the main planting push usually begins as frost risk fades. Warm-season crops generally perform best when they get established promptly.
Peak growth	This is when water, fertility, spacing, and pest pressure have the biggest effect on final yield.
Late-summer decisions	Second plantings can work, but success usually depends on maturity, microclimate, and how warm late summer stays.
Finish window	Plan to have frost-sensitive crops mostly wrapped up by November 19. Cooling nights often slow crops before the first real frost arrives.

Typical season length: 252 frost-free days between the median spring and fall frost dates.
