Planting zones in Tampa-St. Petersburg-Clearwater, FL
This metro spans USDA zones 9a to 10b, so there is no single zone for Tampa-St. Petersburg-Clearwater, FL and anyone who gives you one is rounding. 42% of its ZIP codes are zone 10a; the rest are not.

What you can sow in Tampa-St. Petersburg-Clearwater, FL now
5 of 32 crops that every one of the 12 NOAA stations serving this metro area agrees still has time to mature — with a week in hand, so this holds until the page is next rebuilt.
- 🧅 Green Onions 55d
- 🥬 Swiss Chard 55d
- 🥬 Kale 60d
- 🥬 Collards 60d
- 🥕 Carrots 70d
The freeze dates here cross the new year, so no single range describes them and none is quoted. Each ZIP code's own station is cited in the lookup above.
A further 21 crops depend on where in Tampa-St. Petersburg-Clearwater, FL you are — its stations disagree about them. The ZIP lookup above settles it for one address.
The growing season at one or more of this metro area's stations crosses 1 January, so a one-year bar would have to start the season after it ended. No chart is drawn rather than a misleading one.
Which zone you are in depends where you are
Tampa-St. Petersburg-Clearwater, FL covers 4 hardiness zones. A guide that gives the metro one zone has picked whichever is largest and rounded everyone else into it — which is fine for the 42% in zone 10a and wrong for the other 58%. Here is the actual split.
| Zone | ZIP codes | Share | |
|---|---|---|---|
| 10a | 58 | 42% | |
| 9b | 57 | 42% | |
| 10b | 21 | 15% | |
| 9a | 1 | 1% |
Zones are published per ZIP code, so yours is exact even though the metro's is not. The hardiness tool will tell you which one you are in.
Your freeze dates
No freeze range is shown for Tampa-St. Petersburg-Clearwater, FL, because the freeze window here crosses New Year, so an earliest-to-latest range would be arithmetic on dates that do not sit in order. The tools below still answer for individual ZIP codes here, and will say what applies.
Your growing season
NOAA publishes a growing-season length for each station, and across the 12 stations serving Tampa-St. Petersburg-Clearwater, FL it runs 281–365 days . That figure is published, not computed from the two freeze dates — subtracting one from the other gives the wrong answer wherever a season crosses New Year. Mean summer high (June–August) runs 90–93 °F , at or above the 90 °F point where cool-season crops bolt and tomato and pepper pollen fails — so midsummer sowings of lettuce and its relatives are worth holding here. Summer rain over the same months runs 24.1–27.4" across those 10 stations, against the rough inch a week — about 13 inches over the same 92 days — that a vegetable garden is usually reckoned to want. At the middle station that is covered, so watering in Tampa-St. Petersburg-Clearwater, FL is for the gaps between storms rather than the whole season. The inches are NOAA's published normals; the inch a week is a rule of thumb, and it takes no account of a 91 °F summer afternoon drying the soil faster than a cool one.
What survives the winter changes across Tampa-St. Petersburg-Clearwater, FL
Of 74 perennial fruits, nuts, berries, vegetables and herbs, 46 come through the winter in zone 9a and only 24 in zone 10b. That is a different garden at each end of the same metro.
| Zone | ZIPs | Survive | Fail for being too warm |
|---|---|---|---|
| 9a | 1 | 46 of 74 | 25 |
| 9b | 57 | 40 of 74 | 32 |
| 10a | 58 | 25 of 74 | 49 |
| 10b | 21 | 24 of 74 | 50 |
The last column is the counterintuitive one, and it is why the totals do not simply rise as the winters get milder. Most temperate fruit needs a documented number of hours below about 45 °F to break dormancy and set a crop, so an apple fails in a winter that is too warm; currants and rhubarb cook in the summer heat that comes with it. See the full list with reasons.
At least one station here freezes across the new year, which puts the two ends of a spread on opposite sides of the calendar. Drawing it would produce a bar spanning almost the whole year and meaning nothing, so none is drawn.
The 12 stations behind these numbers
All 12 NOAA stations whose normals this page quotes, spanning about 116 km north to south. Every one is named with its identifier in the station list below — this page does not single one out, because no one station speaks for a whole metro area.
A relative sketch, not a map with a projection: longitude is adjusted for latitude so the shape is not stretched, and there is no basemap. For the one station nearest a specific address, with its real distance, use the ZIP lookup above.
Every figure above comes from these, and each is named so you can check it. Which station serves a given ZIP code, and how far away it is, varies across the metro — the table below gives it per ZIP code rather than this page averaging it.
| Station | NOAA ID | Last spring freeze | First fall freeze | Season |
|---|---|---|---|---|
| Brooksville Chin Hill, FL | USC00081046 | February 3 | January 3 | 329 days |
| Brooksville Hernando Co AP, FL | USW00012818 | March 1 | December 5 | 281 days |

| Weeki Wachee, FL | USC00089430 | February 5 | January 1 | 322 days |
These are medians, not averages — NOAA publishes freeze dates as a probability distribution, and half of years freeze later than the date shown.
Every ZIP code in Tampa-St. Petersburg-Clearwater, FL
Zones are published per ZIP code, not per metro area, so this is the exact answer rather than the metro area's average. The station column is the nearest one to that ZIP code's centroid and how far away it is — the same figure the tools use, shown here so you can see which ZIP codes are well covered and which are reaching.

ZIP-code positions are area centroids, so a large rural ZIP code's listed distance is measured from the middle of its area rather than from any particular address in it.

Work out your own dates
Each of these takes a ZIP code and answers for that ZIP alone, citing the station it used and how far away it is. There is a ZIP box in the header of every page.
-
What survives my winter?
Runs on the hardiness zone, so it answers for all of Tampa-St. Petersburg-Clearwater, FL at once — zone across 74 perennial fruits, berries, vegetables and herbs.
- When do I start my seeds?
Dates every spring job from your own last freeze — sow indoors, set out, direct sow.
- When do I sow the next round?
How often each crop is worth re-sowing, and when the next sowing is due.
- What can I still plant?
Counts the growing days left before your first fall freeze, crop by crop.

These metros span exactly the same zones — 9a–10b — so the same plants are in and out of range across them. The freeze dates and the spring calendar are their own.
Gardening in Florida — zones 8b– 11b covers the whole state: how its 1,008 ZIP codes divide between 7 hardiness zones, and the freeze dates across every NOAA station in it.

Where these numbers come from
The hardiness zone is the USDA 2023 Plant Hardiness Zone Map, published per ZIP code by PRISM at Oregon State. The freeze dates are NOAA's 1991–2020 Climate Normals, read from every station whose normals cover a ZIP code in this metro. Nothing here is estimated, and no station stands in for another.
This page names no single station on purpose. Picking one to represent a metro sounds reasonable and is not: the station serving the most ZIP codes is an artifact of where ZIP centroids happen to fall, and it selects a lock on the Monongahela for Pittsburgh and a far southern suburb for Chicago. A range across every station is true; a single cited date for a whole metro is not.
