Direct answer: A fence gate that sticks in humid weather is usually rubbing because the wood has taken on moisture and the clearance was already too tight. Most of the time the fix is a small adjustment at the fence gate hinges or latch, not cutting a lot off the gate right away.
Most likely: The most likely cause is a wood fence gate with marginal clearance that swells just enough on damp days to bind at the latch side or bottom corner.
Start by finding the exact rub point. A gate that swells and a gate that sags can feel almost the same at the handle, but they leave different clues. Reality check: wood gates move a little with the seasons, so the goal is proper clearance and alignment, not a perfectly zero-gap fit year-round.
Don’t start with: Do not start by trimming the whole gate heavily. That is the common wrong move, and it often leaves an ugly oversized gap once the weather dries out.
The gate swings mostly fine, then gets tight right before it closes or the latch will not line up on muggy days.
Start here: Check the gap between the latch edge and the post for shiny rub spots, compressed wood fibers, or latch hardware hitting first.
The free end drops slightly and the bottom corner scrapes dirt, concrete, or the lower post area.
Start here: Check for loose fence gate hinge screws, a twisted gate frame, or a leaning hinge post before blaming swelling alone.
The gate feels tight through a broad section, not just one corner, especially after rain or morning dew.
Start here: Look for swollen boards, a bowed gate, or finish failure that lets the wood take on moisture.
The gate closes, but you have to lift, shove, or slam it to catch the latch when the air is damp.
Start here: Check whether the fence gate latch strike is set too tight and whether the gate has enough seasonal clearance.
This is the usual cause when the problem shows up mainly in humid weather and improves when things dry out.
Quick check: Slip a thin spacer or paint stir stick along the latch-side gap and top gap. If clearance is already minimal, swelling alone can make it bind.
A gate can feel like it swelled when the real problem is a small drop at the free end that only becomes noticeable once the wood expands.
Quick check: Lift the latch-side end by hand. If the gate moves upward at the hinges or the screws shift, the hinges need attention.
Sometimes the gate itself clears, but the latch tongue, catch, or strike plate loses alignment when the wood grows a little.
Quick check: Close the gate slowly and watch the latch hardware. If metal hits before the wood does, start with latch adjustment.
If the post leans, footing loosens, or the gate frame racks out of square, humidity just makes an existing alignment problem worse.
Quick check: Sight down the hinge post and compare the gap at top and bottom. A widening or narrowing gap points to movement, not just surface swelling.
You need the real contact point before you adjust hardware or trim anything. Most wasted work happens when people guess.
Next move: You now know whether the problem is latch-side swelling, hinge sag, bottom drag, or a broad swelling issue across the gate. If you cannot find one clear rub point, the gate may be racked, the post may be moving, or more than one issue is stacked together.
What to conclude: A single tight area usually points to adjustment. Broad contact across a wider section points more toward swelling or frame movement.
A small hinge drop is more common than people think, and humidity makes that small drop show up as a stuck gate.
Next move: If the gate clears and latches normally after tightening, the main problem was hinge sag, with humidity only making it more noticeable. If the gate still binds at the same spot and the hinges are solid, move on to latch clearance and wood swelling checks.
What to conclude: Loose or worn hinges are a direct repair path. Solid hinges with the same rub pattern point back to clearance or post movement.
A tight latch setup can mimic a swollen gate. This is an easy fix and should be ruled out before trimming wood.
Next move: If the gate now closes without force and the wood is no longer rubbing, the latch alignment was the real issue. If the latch is no longer the problem but the gate still rubs wood-to-post, the gate needs clearance correction or the post/frame needs repair.
This is where you separate a small seasonal adjustment from a structural problem that will keep coming back.
Next move: If the post is stable and the gate is square, you are likely dealing with ordinary wood movement and a clearance issue. If the post moves, the opening is out of square, or the gate frame is racked, simple trimming will not hold for long.
Once you know the cause, the right fix is usually modest. The goal is a gate that works in wet weather without looking sloppy in dry weather.
A good result: The gate should open and close smoothly in humid weather without dragging, rubbing hard, or needing a shoulder shove.
If not: If the gate still binds after small corrections, the post or frame geometry is off enough that it needs a more involved rebuild or reset.
What to conclude: A successful small correction confirms you found the real cause. A gate that still fights you usually has a structural alignment problem behind the swelling complaint.

Wood takes on moisture from damp air and rain, so a gate with already-tight clearance can grow just enough to rub. Humidity often exposes a small alignment problem that was already there.
Usually no. First tighten the fence gate hinges and check the latch alignment. If you cut too much before confirming the rub point, the gate can end up with an oversized gap once the weather dries out.
Enough that it still swings and latches during wet weather without looking sloppy in dry weather. The exact number depends on the gate and hardware, but a little working room is better than a tight showroom fit outdoors.
Yes. If the latch tongue, catch, or strike hits first, the gate can feel stuck even when the wood is not the main problem. Watch the latch area closely while closing the gate slowly.
That usually means the screws are stripped, the hinge is worn, or the hinge post is moving. Repeated loosening is a sign that simple adjustment is not enough anymore.
If the hinge post leans, rocks in the ground, or the opening is visibly out of square, the post or footing is the bigger issue. In that case trimming the gate is just masking the problem.
