Clearwater vs Siesta Key Beach: Sea Temperature, Rain Days, Parking and Lodging Tax

FLORIDA · TWO GULF BEACHES · CLEARWATER VS SIESTA KEY

Two Gulf beaches, one week of vacation, and a traveler with both tabs open. Siesta Key Beach took the U.S. News title of best beach in the country for 2026. Clearwater sits inside a cluster of three state-park islands that Florida measures down to the foot of boardwalk, one of which holds 2,021 parking spaces.

What sorts them is short: how warm the water is in the month you fly, how many wet days the summer carries, and whether your car has anywhere to sit when you arrive. The air temperature, which is what most people compare first, is the closest thing on the whole page to a tie.

The full detail of each beach lives on its own pages: Siesta Key Beach in one place, and Clearwater month by month, starting with January. One thing they share outright, whichever way you lean: the Atlantic hurricane season runs June 1 to November 30 for both, and the statewide view of that calendar is in the best time to visit Florida.

Clearwater or Siesta Key Beach

If the trip is the beach day itself, book Siesta Key Beach. The sand is quartz crystal, the water off it averages 65.2°F in January against 61.7°F off Clearwater, and the July wet-day count runs 10.7 against 12.6 at the same 0.10-inch threshold. U.S. News ranked Siesta Beach the best in the United States for 2026, and nothing in the Clearwater file competes with that particular claim.

Clearwater is the better base for anyone driving to the sand on a peak-season Saturday, and for anyone who wants three beaches rather than one. Honeymoon Island State Park holds 2,021 parking spaces, the largest count of any state park in Florida’s 2024 inventory, against 976 at Siesta Key Public Beach and Pavilion. The airport helps too: PIE boarded 1,228,048 passengers in calendar 2024, an FAA small hub, with its terminal between St. Petersburg and Clearwater.

The air barely separates them, whatever the brochures imply. Overnight lows sit within 1.6°F of each other in every month of the year, and Clearwater carries the warmer figure all twelve times. From April through September the afternoon highs differ by 1.3°F or less. Daylight on January 15 runs 10 hours 36 minutes at one and 10 hours 39 minutes at the other. Storm dates match exactly, June 1 to November 30.

Check one thing before you decide: what time you expect to reach the sand. Visit Sarasota County says the Siesta lots fill fast at peak times and through the January-to-April peak season, and the free 77 Islander trolley runs daily, roughly every 30 minutes from 8 to 10 a.m. Around Clearwater the constraint is shaped differently. The state counts no parking at all at Caladesi Island or Anclote Key, both reached by ferry or by your own boat.

Clearwater vs Siesta Key Beach weather: temperature, rain and sea

Air figures are 1991-2020 NOAA normals, one station per beach, and sea figures are a 2015-2024 marine average of daily maxima, which runs a shade warmer than a 24-hour mean on both sides.

Siesta Key posts the higher afternoon average in all twelve months, but the size of that lead swings hard: 0.4°F in May and June, 2.1°F in October, 2.8°F in November, 2.4°F in December. It widens in late fall, which is also when the bay-side gauge at PIE loses the sea breeze that works on Clearwater Beach. Look at the overnight column and the ranking reverses: Clearwater’s low is the warmer figure every month, from 0.2°F apart in January to 1.6°F apart in May.

January is where the water parts company, 65.2°F off Siesta Key against 61.7°F off Clearwater, with December at 68.1°F against 65.5°F. Neither is a warm bath, but 3.5°F decides whether a winter swimmer stays in past five minutes. By June the two readings are identical at 86.3°F, and in July Clearwater is warmer by 0.1°F, which is noise. Anyone booking a summer swim gains nothing by choosing on sea temperature.

Clearwater and Siesta Key Beach weather averages

Clearwater’s normals come from NOAA station USW00012873, listed as ST PETERSBURG INTL AP. The gauge sits at PIE, between St. Petersburg and Clearwater, on the bay side rather than the Gulf. Siesta Key’s come from USW00012871 at Sarasota-Bradenton, the same station that serves the key itself, same place and same air. That siting is why the afternoon maximum carries nearly all of the difference between the two columns and the overnight low carries almost none.

Both rain-day counts use the identical NOAA cutoff, 0.10 inch in 24 hours, and both series also carry a count of days at an inch or more. Those columns compare directly, with no station caveat attached: 12.6 wet days against 10.7 in July, 2.8 heavy days against 2.3, and 4.5 against 3.6 in January.

Permits and rules in Clearwater and Siesta Key Beach

Florida’s Department of Environmental Protection counted every facility in its 2024 Recreational Facilities Inventory, and around Clearwater the counts are lopsided by design. Honeymoon Island State Park: 2,021 parking spaces, 4 miles of beach, one designated swimming area, 3.4 miles of hiking trail, 1,671 feet of boardwalk. Caladesi Island: 3 miles of beach, 2.5 miles of trail, one canoe, kayak and tube launch, and not one parking space. Anclote Key Preserve: 6.7 miles of beach, 1,408 feet of boardwalk, no parking counted either.

Siesta Key’s counts come from a different publisher, Visit Sarasota County rather than the state: 976 spaces at the public beach and pavilion, and numbered accesses 2, 3, 10 and 13 that are pedestrian, with no parking or a single accessible space. We have not found an equivalent state facility count for the key. On the Clearwater side we could not read a park entrance fee or an opening hour at all, because the operator pages we tried on September 11, 2026 returned errors or rendered only in a browser. That is a gap in our reading, not evidence that no fee exists.

Two practical consequences for a single day. A Caladesi day gets built around a boat or a ferry departure, since the car has nowhere to stop at the other end. A Siesta day between January and April gets built around the clock, because the 976 spaces fill fast and the free trolley covering for them runs every 30 minutes or so between 8 and 10 a.m. Call or check each park for gate fees and hours before you drive, since we could not read them.

Tourist tax and ticket prices in Clearwater and Siesta Key Beach

Pinellas County levies a 6.0% transient rental tax on every night booked, collected alongside the 6% state sales tax, per Florida Department of Revenue form DR-15TDT, revision 03/25. The ceiling that decides your bill is the total: 12% on the nightly rate you were quoted, applied before any resort fee, which the property sets itself and which is not a tax at all. For Sarasota County we did not find an equivalent published rate in our sources, so the two totals cannot be set side by side here.

The named tickets on the Siesta Key side both cost nothing. The 77 Islander trolley is free and runs daily, roughly every 30 minutes from 8 to 10 a.m. The BayRunner is free as well and covers Lido Key every 20 to 30 minutes from 8 a.m. to noon. Our Clearwater sources carry no fare of any kind: no bus fare, no park entrance fee, no opening hour survived the read of September 11, 2026.

Neither side of this comparison carries a room rate. No nightly hotel series, no vacation-rental average, no restaurant check, which means nobody here can call one beach cheaper than the other, and we are not going to imply it. The same applies to crowd counts. The parking totals, 2,021 against 976, are the closest thing to a crowd signal either county publishes.

Things to do in Clearwater vs Siesta Key Beach

Clearwater’s side of the ledger is islands. Three carry state-counted beach: 4 miles at Honeymoon Island, 3 at Caladesi, 6.7 at Anclote Key, and two of the three cannot be driven to. Honeymoon adds 3.4 miles of hiking trail and 1,671 feet of boardwalk, Anclote another 1,408 feet, Caladesi 2.5 miles of trail and a launch for a canoe, kayak or tube. A ferry ticket or your own boat opens 9.7 miles of beach that no car reaches.

Siesta Key answers with sand and a shorter walk. The quartz-crystal grains and the soft turquoise water are why U.S. News ranked Siesta Beach first in the country for 2026, and the key carries two more beaches that get mistaken for it: Turtle Beach and Crescent Beach are separate places, not alternative names for the same strand. The free 77 Islander trolley runs the key daily, and the BayRunner puts Lido Key on a 20-to-30-minute headway when one beach is not enough.

Clearwater or Siesta Key Beach by month

January splits the two wider than any other month of the year. The water off Siesta Key averages 65.2°F against 61.7°F off Clearwater, a 3.5°F gap that no other month comes near, while wet days run 3.6 against 4.5 at the same 0.10-inch threshold and afternoon highs sit at 72.5°F and 70.6°F. If that is your month, read Clearwater in January next to the Siesta Key Beach guide, and keep February in view: the Clearwater sea jumps 3.5°F between the two.

The last word

Decide on two questions and stop comparing: the month you fly, and the hour you expect to reach the sand. January favors Siesta Key by 3.5°F of water. A car-borne Saturday favors Honeymoon Island by more than a thousand parking spaces. One last figure from the two thermometers, since averages hide it: Sarasota-Bradenton records 0.8 January nights at or below 32°F, PIE just 0.3. Neither will touch your beach day, and both are a reminder that the gauges sit inland while you will be standing on the Gulf.
