Weather in November — Sebastian, Florida

November brings Sebastian its first cool nights, with the Vero Beach normal low sliding from 64.7 degrees on November 1 to 58.8 on November 30 while afternoons stay near 79.

Across the month the NOAA NCEI normals for the Vero Beach airport, the climate station south of Sebastian, average 79.3 over 61.4, a mean of 70.4. The November daily normals put the high at 81.8 on the first of the month and 77.2 on the last. Afternoon heat is mostly gone: NOAA's threshold counts average only 0.2 November days at 90 degrees, while 3.5 nights drop to 50 or below.

NWS Melbourne's season onset study tracks the first reading below 50 degrees, which it calls the start of the colder season, to around November 13 at Vero Beach and November 10 at Melbourne. The Melbourne normals, from the Brevard County airport north of Micco, run about two degrees cooler than Vero Beach in November, at 77.3 over 60.8.

Not much: November rain at the Vero Beach station near Sebastian normally totals 2.91 inches on about 5 days with a tenth of an inch or more, less than half of September's total.

The NOAA rainfall quartiles show a dry month with occasional exceptions. One November in four at Vero Beach brings less than 1.18 inches, and one in four brings more than 4.28. Only 0.7 November days a year produce an inch or more. The Melbourne station north of the Sebastian River averages 2.55 inches.

November 2025 was the extreme case. The NWS Melbourne summary for November 2025 recorded 0.03 inches of rain at Vero Beach, flagged as a new record, below the previous driest November of 0.11 inches in 1970. Measurable rain fell on just 2 days, no thunderstorm was logged all month, and the station counted 18 days with fog instead.

From November through April, Sebastian normally gets about 16.9 inches of rain at the Vero Beach station, less than a third of the 53.25 inch yearly total, so the six months starting in November are the city's dry half of the year.

Adding the monthly values in the Vero Beach normals gives 2.91 inches for November, 2.54 for December, 2.74 for January, 2.20 for February, 3.44 for March and 3.06 for April. February is the driest single month.

Fog replaces thunderstorms as the common weather entry. In November 2025, the Vero Beach report logged fog on 18 days, 6 of them with visibility of a quarter mile or less, and no thunderstorms at the station that stands in for Sebastian.

The 2026 to 2027 season may not be typical. In October 2026, the NWS Melbourne season pages carried an outlook headline, Increased Potential for Well Above Normal Rainfall and Severe Weather This Upcoming Dry Season, covering November 2026 through April 2027 for east central Florida, a forecast area that includes Sebastian, Fellsmere, Roseland and the rest of Indian River County.

November 2025 was cool and record dry at Vero Beach, with an average low of 56.8 degrees, 4.6 below normal, and only 0.03 inches of rain.

The coldest morning, 40 degrees on November 11, 2025, came with the month's strongest wind, a 38 mph gust from the north on the same day. The warmest afternoon was 86 on November 8. The month's 4.6 degree deficit in the average low at the station south of Sebastian was far larger than the 1.0 degree deficit in the average high.

November records at Vero Beach run from 92 degrees, set on November 6, 2002 and November 5, 1992, down to 31 on November 25, 1970.

Yes: Hurricane Nicole came ashore on North Hutchinson Island just south of Vero Beach on November 10, 2022, and Sebastian recorded a 79 mph peak wind.

The National Hurricane Center ends the Atlantic season on November 30 but notes that tropical cyclone activity sometimes occurs after that date. Nicole proved that a late storm can reach the Sebastian coast. The National Hurricane Center update issued at 3 a.m. EST on November 10, 2022 placed the center on North Hutchinson Island just south of Vero Beach, with maximum sustained winds estimated at 75 mph and a minimum pressure of 981 mb.

Sebastian Daily reported that morning that the highest wind clocked in Sebastian was 79 mph around 2:30 a.m., that docks were severely damaged at several waterfront businesses, and that 26,000 homes in Indian River County lost power. Storm surge left debris on Indian River Drive, which city crews were already clearing, and the paper concluded that Sebastian had minimal damage overall despite winds near 80 mph.

The same report traced the eye of the storm over Sebastian, Fellsmere, Micco and Vero Beach overnight, and found sailboats beached near the dock at Barefoot Bay and at Fisherman's Landing on the riverfront. By morning, Florida Power and Light had restored power to 9,600 Indian River County homes. Nicole was a Category 1 storm crossing a coast where November water still averages about 79 degrees offshore.

November water off Sebastian Inlet falls into the high 70s, pelicans return to Pelican Island, and the Sebastian Clambake fills Riverview Park on the first full weekend of the month in 2026.

The NOAA NCEI Coastal Water Temperature Guide lists November averages of 78.7 degrees at the Canaveral offshore buoy, 79.1 at Lake Worth Pier and 74.5 at the shallow Trident Pier, which drops 6.5 degrees from October. With the Vero Beach air mean at 70.4, the ocean beside Sebastian Inlet State Park now runs about eight degrees warmer than the air.

On the lagoon, the U.S. Fish and Wildlife Service treats the months from fall to spring as prime viewing at Pelican Island National Wildlife Refuge, the island in the Indian River Lagoon near Sebastian, when migratory white pelicans arrive and brown pelicans nest. The refuge was created in 1903 to safeguard the last remaining nesting habitat for brown pelicans and other wading birds on the East Coast, so November marks the start of the season it was built for.

The Sebastian Clambake Foundation has scheduled the 23rd Annual Sebastian Clambake for November 7 and 8, 2026 at Riverview Park. Gates run from 11 in the morning until 9 at night on the Saturday and until 5 on the Sunday, and entry costs nothing, with food and festival shirts sold on site. The City of Sebastian lists the Clam Bake Festival among the major annual events at the park on the Indian River.
