Tree safety during storm season in Pretoria
Pretoria's storm season runs roughly from October to March, and it is when most tree damage in the city happens. A little preparation in calm weather does more good than a scramble afterwards. This guide covers what to check and what to do when the weather turns.
What the season brings
Highveld storms are short and violent. Hail, lightning and sudden strong winds arrive together, often after a long dry spell when the ground is hard, and then again when the ground is saturated and soft. Trees face both: wind that loads the crown, and soil that no longer holds the root plate.
Those two things together explain most of the damage. A tree can stand for decades and then fail in a single storm, not because it was weak in general but because the wind was strong enough and the ground was wet enough at the same moment.
What to check before the storms
The time to look at your trees is before the season, in calm weather. Check the base of any large tree for a lifted root plate, cracks in the ground or a hollow trunk. Check the trunk for splits, especially at a fork. Check the crown for dead wood, broken limbs caught in the branches, and branches that have grown over a roof, a driveway or a power line.
Then look at what is underneath. A tree over open lawn is a smaller concern than the same tree over a bedroom, a carport or a boundary wall. The tree that matters most is the one whose failure would hit something you cannot replace.
Work worth doing in advance
- Remove dead wood from mature trees so the wind has less to break off.
- Thin a crown that has grown dense, so wind passes through rather than pushing on it.
- Lift or clear branches that overhang a roof, a driveway or a walkway.
- Have a large or leaning tree assessed before the season starts.
- Keep gutters and drainage clear so water does not pool around root plates.
During a storm
Stay inside and away from windows, and keep clear of large trees until the weather has passed. Do not go out to move a fallen branch while the wind is still up, and do not park under a mature tree. If a power line comes down, stay well away and treat it as live.
It is worth knowing where your electricity and water shut-offs are, in case a falling tree damages a service. Keep a torch and a charged phone handy, because storms often take power with them.
When a tree comes down
Wait until it is safe, then assess from a distance. Keep everyone away from a fallen or leaning tree, because it can still move and a limb resting on a structure may be under tension. Do not cut anything yourself, and do not let anyone else start cutting a jammed or leaning tree.
If a tree or branch is on a power line, phone the utility and keep clear. A contractor cannot work near a live line; the utility has to make it safe first. Photograph the situation so you can describe it accurately and get a quote.
Why an emergency removal is different
A tree that has come down in a storm is not a normal removal. It may be resting on something fragile, the ground may be soft, and there is often no room to work. The contractor has to release the load gradually, taking the tree apart in sections rather than pulling or dropping it. That is slower and more careful than a routine felling.
It is also why storm demand is heavy. After a big storm, every contractor in the city is busy at once, and no honest website will promise you a response time. What you can do is send a clear, photographed enquiry and mark it urgent.
Reducing the risk next year
The most economical storm work is the work done before the storm. A tree that is pruned on a sensible cycle, with dead wood removed and heavy growth thinned, gives the wind far less to break off. A tree that has been inspected and found sound is one less thing to worry about when the next storm comes.
If a tree has survived a storm but shifted, cracked or shed large limbs, do not assume it is fine. Have it looked at, because a tree that has been disturbed can fail weeks later, in calm weather, with no warning at all.
Frequently asked questions
When is Pretoria's storm season?
Roughly October to March. That is when most wind, hail and lightning damage to trees happens in the city.
What should I do if a tree falls on my roof?
Keep everyone clear, do not cut anything, and photograph it from a safe distance. Send the photo with your suburb and mark the enquiry urgent.
Should I prune before the season?
Yes. Removing dead wood and thinning a dense crown before the storms starts is the most useful thing you can do in advance.
A branch is resting on a power line. What now?
Stay away and treat the line as live. Phone the utility first. A contractor can only work once it is safe.
Do you promise a fast response after a storm?
No. Demand is heavy and short after a storm, and we do not promise times we cannot control. Urgent enquiries go straight to a local contractor.
