New Yorkers tend to think of tree damage as a winter problem, but the most dangerous wind events of the year often arrive in summer and early fall. Hurricanes, tropical remnants, and violent thunderstorms hit when trees are in full leaf, carrying the heaviest wind load they will see all year. A little prep during the calm early-season months can be the difference between a few lost twigs and a limb through your roof. Here is how to get your trees ready, and when to call for professional storm work.

Why summer storms are the bigger threat
A bare winter tree presents very little surface for wind to push against. The same tree in July, fully leafed out, acts like a sail. Every branch and leaf catches the wind, and the load on limbs and roots multiplies. That is exactly the condition trees are in during the Atlantic hurricane season, which runs through the late summer and fall, and during the convective thunderstorms that roll through the boroughs on hot afternoons.
Add saturated soil from heavy rain, which loosens a tree’s grip on the ground, and you have the recipe for whole trees uprooting and large limbs tearing off. Preparing in the calm early-season months is the only realistic window, because once a storm is in the forecast it is far too late and far too dangerous to start working in the canopy.
Did you know?
A tree in full summer foliage can experience several times the wind load of the same tree bare in winter. That is why a storm that barely fazes a tree in January can bring it down in August, even at similar wind speeds.
Pre-storm inspection: what to look for
Start with a slow walk around each large tree on your property. You are looking for the warning signs that a limb or trunk is likely to fail under load. Check for:
- Dead, broken, or hanging limbs anywhere in the canopy.
- Cracks or splits in major branches or the trunk.
- Tight V-shaped forks with bark pinched inside, a weak union that splits easily.
- A lean that looks new, especially with cracked or heaving soil on one side of the base.
- Mushrooms or shelf-like fungal conks at the root flare or on the trunk, a sign of internal decay.
- Roots that have been cut or paved over recently, or a neighboring tree that came down and left yours suddenly exposed.
Call before the storm, not after
Any crack in a major limb, a fresh lean, fungal conks at the base, or a previously sheltered tree now standing alone all point to elevated failure risk. These are reasons to book a professional risk assessment early in the season rather than hope it holds.
Structural pruning done the right way
Good pruning lowers wind risk in two ways: it removes the dead and weakly attached limbs most likely to break, and careful thinning lets wind filter through the canopy instead of slamming into a solid wall of leaves. But this is one place where doing too much backfires badly.
Topping a tree, or stripping the interior so only foliage tufts remain at the branch tips (often called lion-tailing), actually makes failure more likely. It forces weak, fast regrowth and pushes weight out to the ends of limbs where leverage is highest. Proper structural pruning is measured and selective, and it is best left to a trained arborist who can lighten the canopy without weakening the tree. The goal is a balanced, wind-permeable crown, not a stripped one.
Safety note: The tips here are for general guidance only. Dragonetti Tree Removal is not responsible for any injury, property damage, or cost resulting from action taken based on this content. Tree work is one of the most dangerous jobs there is. Always engage a certified, insured arborist for large-limb removal, climbing, or any cut you are not fully comfortable making from the ground. Never attempt work near power lines. If a branch is touching or close to a utility line, stop and call your power company.
Cabling, bracing, and young-tree support
Pruning is not the only tool. For trees that are structurally valuable but have a known weak point, hardware can help share the load:
- Cabling and bracing: flexible cables or rods installed high in the canopy support weak forks and heavy limbs so they are less likely to split in a gust. This is skilled, specialized work for an arborist, not a DIY project.
- Young and newly planted trees: proper staking can keep a young tree from being whipped over before its roots establish, but stakes must be removed once the tree can stand on its own, or they cause more harm than good.
- Wind-smart planting: when you replace a tree, choosing a sturdier, well-sited species and giving roots room to spread pays off for decades of future storms.
Your pre-storm checklist
| Task | When | Who |
|---|---|---|
| Walk the property and inspect each large tree | Late spring | Homeowner |
| Book a risk assessment for any warning signs | Early summer | Arborist |
| Remove dead, hanging, and weak limbs | Early to midsummer | Arborist |
| Install cabling or bracing where needed | Early to midsummer | Arborist |
| Clear loose debris and secure yard items | Storm in forecast | Homeowner |
Pro tip
Schedule tree work early in the season. As soon as a major storm enters the forecast, every arborist in the region is booked solid, and no one will safely climb a tree in rising wind. The homeowners who fare best are the ones who handled their pruning back in June.
When the storm is coming, and after
Once a storm is imminent, switch from tree care to safety. Bring in or tie down anything the wind could throw, move vehicles away from large trees and overhanging limbs, and stay out of the canopy entirely. Do not attempt last-minute pruning.
After the storm passes, treat every downed line as live and keep your distance, then call your utility. Never approach a limb that is touching a power line. Hanging limbs and partially failed trees hold enormous stored energy and are some of the most dangerous things a homeowner can try to handle, so leave those to a professional crew with the right equipment and training.

Frequently asked questions
When should I prepare my trees for hurricane season in NYC?
Do the work in late spring and early summer, well before the peak Atlantic hurricane and summer thunderstorm window of roughly August through October. Structural pruning, cabling, and risk inspection all need to happen while conditions are calm, because no reputable arborist will climb or do major work as a storm approaches. Aim to have any corrective pruning finished by midsummer. Once a named storm is in the forecast it is too late for anything but clearing obvious loose debris and securing yard items, so think of tree prep as an early-season maintenance task, not a last-minute scramble.
Does pruning really make a tree safer in high wind?
Done correctly, yes. Thoughtful pruning removes dead and weakly attached limbs that are the most likely to break, and selective thinning lets wind pass through the canopy instead of pushing against a solid sail of foliage. The key word is correctly. Topping a tree or stripping its interior so only tufts remain at the branch ends actually makes failure more likely, because it forces weak regrowth and shifts weight to the tips. Proper structural pruning by a trained arborist lowers risk, while aggressive over-pruning raises it, which is why this is not a good place to guess.
Which trees are most likely to fail in a summer storm?
Trees in full leaf carry the highest wind load of the year, so summer and early fall storms are especially dangerous. The highest-risk trees are ones with dead or hanging limbs, included bark in tight V-shaped forks, cracks in major branches, a leaning trunk with heaving or cracked soil at the base, fungal conks at the root flare, or a history of past limb failures. Shallow-rooted species and trees that were recently exposed when a neighboring tree came down are also more prone to blowing over. Any of these signs warrants a professional risk assessment before storm season.
What should I do with my trees right before a storm hits?
By the time a storm is imminent, focus on safety rather than tree work. Walk the property and remove or secure anything the wind could throw, such as furniture, planters, and loose branches already on the ground. Park vehicles away from large trees and overhanging limbs. Do not attempt last-minute pruning or climbing, and never go near a limb that is touching a power line. After the storm, keep clear of downed wires, assume any fallen line is live, and call your utility, then bring in a professional for any hanging limbs or partially failed trees, which are extremely dangerous to handle.
