Pacific Northwest trees are adapted to wet winters, but summer drought stress is a real and recurring issue across the Portland metro and Sherwood area. Knowing what to look for in June, before heat peaks in July and August, gives you the most options for protecting the trees on your property.
Watch for these signs on conifers and deciduous trees alike. Needle browning that starts at the tips and works inward is a classic drought stress response in Douglas firs and cedars. On big-leaf maples and other broadleaf species, leaf margins may show early scorch or premature drop. Bark that looks drier or more fissured than usual on previously healthy trees, or any visible weeping resin or sap, can indicate stress or insect activity that warrants a closer look.
Root zone issues often show up in summer before any above-ground signs appear. Trees planted too deep, or in compacted soil near driveways and structures, may show decline faster as moisture drops. An ISA-certified arborist can help you differentiate normal seasonal changes from early indicators of a real problem.

Authentic job photo preferred: an arborist inspecting a large tree in a residential yard, ideally showing close evaluation of the trunk, bark, or upper canopy. A photo that communicates detailed, professional assessment carries the educational tone of this post effectively.
