Canning altitude adjustments in Washington
Washington's featured towns sit about 20 to 2,350 ft — a spread that crosses 2 water-bath bands, so which town your kitchen is in genuinely changes the answer.
The lay of the land
Seattle cans at about 20 ft, but the Cascades hide a much higher Washington behind them: Spokane sits solidly in the 1,001–3,000 ft band, and Yakima and Wenatchee — the towns that actually grow the fruit — straddle the very first band line at 1,000 ft. It's an odd arrangement: the state's biggest kitchens need no adjustment, while its orchard country has to pay attention.
From Seattle at about 20 ft to Spokane at about 2,350 ft, Washington crosses 2 water-bath rows — times as written at the bottom of the state, 5 added minutes at the top. Each band carries one published answer, so find your town's row before the jars go in.
| Town | Elevation | Water bath | Dial gauge | Weighted gauge |
|---|---|---|---|---|
| Seattle | about 20 ft | as written | 11 lb | 10 lb |
| Wenatchee | about 790 ft | as written | 11 lb | 10 lb |
| Yakima | about 1,070 ft | +5 min | 11 lb | 15 lb |
| Ellensburg | about 1,750 ft | +5 min | 11 lb | 15 lb |
| Spokane | about 2,350 ft | +5 min | 12 lb | 15 lb |

Frequently asked questions
Why do different Washington towns get different canning numbers?
Because Washington's featured kitchens climb from about 20 ft in Seattle to about 2,350 ft in Spokane — a spread that crosses 2 water-bath bands. Each band carries its own published answer, so the right move is reading your own town's row, not your neighbor's.
What would the same recipe look like in Seattle versus Spokane?
In Seattle, a water-bath recipe runs exactly as printed, with a dial gauge at 11 lb. In Spokane, the same recipe takes 5 extra minutes, and the dial climbs to 12 lb. Same recipe, different ground.
Is there one setting that covers all of Washington?
Not quite — even the weighted gauge steps once, from 10 lb in the lowest towns to 15 lb everywhere higher, and water-bath minutes and dial settings vary more. Match the row for where the canner actually sits.
