That groups Mukilteo with places like Picnic Point, WA, Lake Stickney, WA and Meadowdale, WA on the same cool-season storm track.

Once Mukilteo passes late-May, overnight freezes fade and peas, lettuce, spinach, and radishes can be sown. Tomatoes and peppers do best set out two weeks later in Mukilteo, once nights clear the mid-40s°F. The season ends by early-October in Mukilteo, once hard frosts set back in. A creek-bottom lot in Mukilteo can lag Mukilteo's last frost 7-10 days behind a south slope.
