In Tampa the wet and storm season runs from June to November, and most of the storm-driven water calls cluster in that window. Repeated afternoon rain, the possibility of tropical systems, bay-side surge risk and the heavy use of cooling systems all shape the calls. This guide sets out the calendar, what each stretch brings and what a homeowner can do before the season begins. Calls are answered 24/7 on (833) 490-5225.
Key takeaways
- The wet and storm season in the region runs from June to November, and rain and storm surge are the main water calls in that window
- Repeated rain is the wet-season problem, because a house can take water twice before the first loss has dried
- Outside the wet season the calls shift toward plumbing, appliances and cooling-system lines
- Bay-side homes take wind and surge risk, and the risk is judged on site when water reaches a building
- The best preparation is done before June: gutters, seals, thresholds and knowing where the main shut-off is
- A second storm through the same opening is a new entry and should be recorded as one
What is the wet and storm season here?
The wet and storm season runs from June to November. Rain and storm surge are the water calls it brings, and the season is the reason repeated losses are common in Tampa.
The season has a regular rhythm of afternoon storms through the summer, and the tropical systems that can reach the region run through the autumn. Rain in the wet season is heavy and repeated, so the ground is saturated for much of the time and drains fill quickly. The result is a pattern in which a house is wet, dries a little and is wet again before the drying has finished.
Outside the wet season, from December to May, the water calls are more often from plumbing, appliances and cooling-system lines, because the storm pattern is quieter. That does not mean no storm water arrives in those months, only that the storm calls are concentrated in the wet season.
What does each stretch of the year bring?
The calendar below sets out what each part of the year tends to bring. It describes the pattern, not a forecast, and it is based on the regional season described above.
The early part of the season brings the first heavy rains, which find the weak points in roofs, gutters and door seals that have not been used since the year before. The middle of the season brings the repeated storms and the highest chance of water through doors and windows. The late part of the season can still bring tropical rain, and the first cold snaps of the year are not a feature of this climate in the way they are farther north. The table shows the stretch and what it tends to bring.
A homeowner who keeps a note of the storms each year can see the local pattern on their own street, which is more useful than any general calendar.
| Stretch | What tends to happen |
|---|---|
| December to May | Outside the wet season: plumbing, appliance and cooling-line losses, and occasional storm rain |
| June to July | The wet season begins; afternoon storm rain and the first repeated rain |
| August to September | Repeated storms, door and window entry, and the bay-side wind and surge risk |
| October | The storm season is still running; Hurricane Milton brought heavy rain and tornadoes to the region in October 2024 |
| November | The season ends, though a late storm can still reach a house; drying runs in the same humid air |
Why does repeated rain cause the worst losses?
A house that is rewetted before it has dried loses the progress of the drying, and the materials that were nearly dry become wet again. Each storm adds water to the same framing and floors.
A single storm is usually cleared in one visit. The problem comes when a second storm arrives while the drying is still running. The materials that had reached their normal level are wet again, and the drying has to restart from the new readings. Over a season this pattern can add a great deal of damage to a building that was never flooded in a single event.
The remedy is to keep the readings going through the season and to record any rise between visits as a new entry. The record also shows the homeowner where the water is entering, so the entry can be sealed before the next storm.
What does the bay side add to the wet season?
Bay-side homes take wind and rain directly, and storm surge is a risk on the low ground. Surge water is judged on site when it reaches a building, and the cleanup follows that judgement.
The bay side of the county, and the Pinellas areas across the water, face the wind and the rain from the bay first. Storm surge is a risk on the low ground near the water, and it was feared for Tampa in Hurricane Milton, although the surge did not arrive. A homeowner on the bay side should plan for the surge case even in years when it does not come.
Surge water that has crossed land is more serious than clean rain, and it is handled that way. The preparation for the bay side is the same as for the rest of the wet season, with the addition of knowing the lowest floor and the lowest door of the house.
How does the heat of the season affect the water calls?
Cooling systems run for long stretches in the warm months, and their condensate lines work hardest then. A blocked line is one of the quieter water losses of the season.
A condensate line that is blocked with algae or dust overflows into the drain pan and then into a ceiling or a closet. The overflow can run for weeks before it is found, because it is small and steady. The warm months are when the lines work hardest, so a homeowner should look at the outdoor end of the line and the pan in the spring.
The humid air of the season also slows the drying of every other loss, and that is why the readings are important in the summer months.
What should a homeowner do before June?
Clear the gutters and downspouts, check the door seals and thresholds, look at the roof edges and flashings, and know where the main water shut-off is. Those steps cost little and shorten the first hour of any loss.
Gutters that are full of leaves overflow in the first storm, and a downspout that discharges against the foundation adds to the water at the wall base. A door seal that has cracked or a threshold that has lifted lets storm water in at the lowest point of the house. The roof edges and the flashings around vents and penetrations are where a leak starts, and they are easy to inspect from the ground with binoculars.
The homeowner should also know where the main shut-off is, and should show it to anyone who may need to close it. Keeping the line's number, (833) 490-5225, in the phone and on the fridge means it is at hand when the storm arrives.
What does the record of a season show?
A simple log of storms, stains and readings shows the pattern on a street and a house. It helps the homeowner decide where to seal and where to watch, and it supports any claim for a loss.
A homeowner can note the date of each storm, the place where water was seen and the wind direction if it is known. Photographs taken from the same spot each time make a change easy to see. Over several seasons the log shows which openings take water and which are sound, and that information is more useful than any general advice.
The crew's readings and photographs add to the log when a loss occurs. Together they give a clear account of the season for the homeowner, the insurer and any repair trade that is asked to look at the house.
How do the calls differ between a house and a business?
A house is judged by its rooms and its household belongings, while a business is judged by its downtime, its stock and its records. The wet season touches both, but the response and the record are planned differently for each.
In a house the calls are mostly about the ground floor, the roof edge and the garage door, and the record is kept for the homeowner and the insurer. In a business the storm call often arrives during trading hours or just before a shift, and the loss is measured by the days the space cannot be used. A shop or an office in the wet season needs a plan for the stock, the access and the working hours, and the response is planned with the owner or manager.
Both kinds of property benefit from the same preparation before June. Clearing the gutters, checking the door seals and knowing the shut-off help a house and a business alike, and a business should also check where its stock sits relative to the lowest door.
What does a homeowner's seasonal check look like?
A short check each spring covers the roof edge, the gutters, the door and window seals, the thresholds and the outdoor drain, and it takes less than an afternoon.
From the ground a homeowner can see the gutters, the downspouts and the roof edges, and can look for dark or lifted shingles and for flashing that is loose at a vent. At the doors and windows, the seals and the thresholds should be firm and free of gaps, and the lowest door should close fully. The outdoor drain and the downspout should carry water away from the wall.
A homeowner who finds a fault in the check should note it and arrange the repair with the trade that does that work. The water work is not the trade that repairs the roof, the door or the drain, and the record of the check is useful if a loss happens later.
Frequently asked questions
Is every storm in the wet season a water call?
No. Many storms pass without entering a house. The calls come when rain or surge finds an opening, a weak point or a full drain.
Do I need to act differently before June?
Yes, the preparation is best done before the season starts: clear the gutters, check the seals and the thresholds, and know the shut-off.
Are the months outside the season safe from water?
They are safer from storm water, but plumbing, appliance and cooling-line losses can happen in any month, and the line is answered 24/7.
What is the single best step a homeowner can take?
Call as soon as water is seen, and shut off the source if that is safe. Early calls shorten the drying and reduce the number of materials lost.
Does this calendar predict a storm?
No. It describes the usual pattern of the season, and it does not forecast any particular storm. For forecasts, use the National Weather Service.
