Tampa is under the strictest watering rules the region has seen in years. The Southwest Florida Water Management District declared a Modified Phase III Extreme Water Shortage and has extended it through October 1, 2026, after a rainy season that never delivered; the district’s rainfall deficit hit 11.4 inches in May. Whether you are in Hyde Park, Seminole Heights, Westchase, Carrollwood, or New Tampa, one-day-a-week watering is the law right now. Here is the schedule, the fine print, and a month-by-month plan for keeping a Tampa lawn alive on it.
Your Tampa watering day
Your day is set by the last digit of your street address:
- Ends in 0 or 1: Monday
- Ends in 2 or 3: Tuesday
- Ends in 4 or 5: Wednesday
- Ends in 6 or 7: Thursday
- Ends in 8 or 9: Friday
Inside the City of Tampa, watering is prohibited between 4 a.m. and 8 p.m. every day. That leaves midnight to 4 a.m. or 8 p.m. to midnight on your one day, and properties under an acre should plan on using a single window, not both. Hand watering the lawn counts too, and it belongs on your designated day. Every automatic system is also required to have a working rain sensor, so a July thunderstorm does not trigger a violation-by-timer the next morning.
What still runs on other days
Low-volume methods are treated more gently. Drip and micro-irrigation for beds, shrubs, and trees, and hand watering of anything that is not lawn, are allowed any day, just not between the daytime cutoff hours. Reclaimed water is generally exempt from the schedule. If your landscape leans on established beds and trees rather than wall-to-wall turf, Phase III barely touches most of it.
New sod and plantings
New landscapes need establishment water that a one-day schedule cannot provide, and the district’s order includes tighter allowances for new plantings on a declining schedule. If you are planning sod or a renovation this year, time it around the rules and check the current establishment allowance before installation day, not after.
2026 Tampa lawn care calendar
Tampa lawns are St. Augustine and Bahia country, and the calendar follows the rain.
- Spring (Mar to May): the dry season’s tail end and the hardest stretch of Phase III. Mow St. Augustine high, 3.5 to 4 inches, water deep on your one day, and hold off on heavy fertilizing until the lawn can drink.
- Summer (Jun to Sep): daily storms carry most of the load once the rainy season arrives. Let the rain sensor do its job, watch for chinch bugs in the hot weeks between storms, and keep mower blades sharp because wet-season growth is fast.
- Fall (Oct to Nov): the district decides in October whether restrictions ease. Recovery work happens here: patch thin areas, top-dress, and fertilize while soil is still warm.
- Winter (Dec to Feb): growth slows and water needs drop. One deep watering on your day is usually plenty, and it is the season for design, hardscape, and tree work.
A lawn built for one-day watering
Cycle-and-soak matters in our sandy soils: split the single watering into two shorter runs an hour apart so it soaks in instead of draining straight through. High-efficiency nozzles and a tuned system stretch the one window further. And shifting the hardest corners of the yard from turf to Florida-friendly beds on drip removes them from the schedule entirely.
The bottom line for 2026
Know your digit, water only in the legal windows, keep the rain sensor working, lean on drip for everything that is not grass, and mow tall through the stress months. Phase III runs at least into October, so the lawns that look good this year are the ones managed for it, not against it.
If you would like help tuning irrigation to the one-day schedule, repairing a system, or converting thirsty corners to Florida-friendly planting, the Tampa Pro Landscape Team works with these exact rules every day.
