Recent National Weather Service guidance and ensemble models project a daily maximum near 76–80°F in Seattle on June 21, 2026, under a strengthening upper-level ridge that favors subsidence warming and reduced cloud cover. Onshore flow from the Pacific and the moderating influence of Puget Sound waters introduce uncertainty in the precise peak, keeping 78–79°F and 80–81°F bins closely matched in trader pricing. Seasonal context of above-average early-summer temperatures, with limited marine-layer intrusion expected, supports the current distribution while highlighting sensitivity to small shifts in wind direction or timing of any ridge axis passage.
