The National Interagency Fire Center's Predictive Services unit has issued its seasonal outlook for summer 2026, and for residents of Oregon, Washington, and Idaho, the message is sobering: above-normal significant fire potential is expected across the entire Northwest Geographic Area from July through September, with no indication of late-season relief in current climate models.

The Setup: Snowpack and Drought

The underpinning of this year's elevated fire outlook is a snowpack deficit that developed over the winter of 2025–26. Much of the Cascade Range and Northern Rocky Mountains saw below-average snowfall, and the snowpack melted out weeks earlier than normal in many drainages across Oregon, Washington, and Idaho.

The early snowmelt, combined with below-average spring precipitation, accelerated fuel curing — the process by which living green vegetation dries to the point it can readily carry fire. As of early June, fuels in lower-elevation zones of eastern Oregon and southern Idaho were already registering moisture levels typical of late July or August.

Month-by-Month Forecast

The NIFC outlook covers the period from July through September 2026, with the following broad patterns for the Northwest:

  • July: Above-normal fire potential across most of Oregon, Washington, and Idaho. The eastern portions of these states — including the Columbia Basin, Blue Mountains, and southern Idaho rangeland — are highlighted as areas of greatest concern.
  • August: Continued above-normal potential across the entire region. This is historically the most active month for large fires in the Northwest.
  • September: "With no indication of late-season relief, September's significant fire potential is also expected to remain above normal across the entire Northwest Geographic Area," according to NIFC's outlook language.

What Fire Managers Are Doing

In response to the elevated outlook, fire agencies across Oregon, Washington, and Idaho have been pre-positioning resources and increasing staffing levels:

  • The Oregon Department of Forestry entered fire season early and has additional engines and crews staged at strategic locations statewide
  • Washington DNR's fire management program has been monitoring conditions throughout the spring and has activated seasonal firefighting contracts earlier than typical
  • The U.S. Forest Service's Northwest Region has been coordinating with the Northwest Interagency Coordination Center (NWCC) in Portland on resource pre-positioning and staffing levels
  • BLM Oregon and BLM Idaho have increased patrol aviation and aerial detection hours in high-risk areas

La Nina and Climate Context

Climate scientists note that 2026 is emerging from a La Nina pattern that typically brings drier-than-average winters to the Pacific Northwest. The combination of a La Nina-driven dry winter and an early spring heat surge has set the stage for what could be a historically active fire season.

With 2.5 million acres already burned nationally as of mid-June — well above the 10-year average of 1.43 million — the broader national fire situation provides important context. If trends continue, 2026 could challenge recent record-setting years for total acreage burned in the United States.
