Weather in February — Sebastian, Florida

A normal February in Sebastian brings afternoon highs of 75.6°F, overnight lows of 54.5°F and 2.20 inches of rain, the smallest monthly rainfall total in the Vero Beach normals.

NOAA's 1991 to 2020 normals for the Vero Beach airport station, the long record for Sebastian and the rest of north Indian River County, put the February mean at 65.0°F, up 2.2 degrees from January (NOAA NCEI monthly normals). February rain is the leanest of the year at Vero Beach: 2.20 inches, against 2.54 inches in December and 3.06 inches in April.

Februaries around Sebastian and the rest of the Treasure Coast are sunny, dry and cool at night. The Vero Beach normals count only 3.6 February days with a tenth of an inch of rain and 0.5 days with an inch, along with 9.4 nights under 50°F and 2.3 nights under 40°F. At 21.1 degrees, the normal spread between the February high and low is the widest of any month at the station.

The February extremes at Vero Beach run from 90°F on February 24, 2019 to 26°F on February 1, 2026, according to the NWS Melbourne climate report (NWS Melbourne February 2026 climate report, IEM archive). The wettest February on the record brought 9.96 inches in 1983, and the driest just 0.04 inches in 2001.

February is the coolest month of the year for offshore water near Sebastian, with the Canaveral buoy averaging 71.8°F, and the Indian River Lagoon reaches its annual low in late February.

In NOAA's monthly averages, the Canaveral buoy east of Cape Canaveral dips to 71.8°F in February, its lowest of the year, while Trident Pier at Port Canaveral has already climbed to 68.9°F from January's 66.8°F (NOAA Coastal Water Temperature Guide). Lake Worth Pier, the nearest station south of Sebastian Inlet and Wabasso Beach, averages 74.8°F.

The gap between beach and offshore readings narrows quickly in February near Sebastian Inlet State Park. Trident Pier sits 2.9 degrees below the Canaveral buoy in February, down from 6.1 degrees in January, and by March the pier average of 74.4°F has passed the buoy's 72.0°F. February is the turning point on both NOAA records.

Lagoon water behind Sebastian follows the same calendar. A Florida Atlantic University study of Indian River Lagoon water temperatures between Sebastian and St. Lucie inlets found that the winter record shows the annual minimum temperatures in late February (FAU Indian River Lagoon water temperature study). That puts the coldest lagoon water off Riverview Park and the Sebastian River in the same weeks as the coldest offshore water.

February 2026 opened with the coldest February morning on the Vero Beach record, 26°F on February 1, and finished the month 4.5 degrees below normal for Sebastian and Indian River County.

The February 1, 2026 low set a new February record at Vero Beach, beating the 28°F of February 24, 1989 that stood in the 2025 report (NWS Melbourne February 2025 climate report, IEM archive). The station logged 4 nights at or below freezing during the month, against a normal of 0.3, and the average low ran 6.8 degrees below normal at 47.7°F (February 2026 report).

February 2026 was not dry in Sebastian's records. Rain totaled 2.88 inches, 0.68 above normal, and 2.40 inches of it fell between February 27 and February 28. The same front brought the month's strongest wind on February 27: 35 mph sustained and a 46 mph gust from the northwest. Thunder was heard on 3 days.

The month still warmed by its end, with the warmest afternoons at 86°F on February 20 and February 27. Fog formed on 15 days, though only 2 had visibility of a quarter mile or less, far fewer than the 10 dense fog days that February 2025 produced at the station serving Sebastian.

Skies over Sebastian were mostly clear in February 2026. The Vero Beach report classed 20 days as fair, 7 as partly cloudy and 1 as cloudy, with an average sky cover of 0.24 and an average relative humidity of 69 percent. The average wind speed for the month was 8.1 mph.

February 2025 was the warm, wet opposite of 2026 in Sebastian's records, with a mean of 69.1°F, 4.1 degrees above normal, and 6.15 inches of rain at Vero Beach.

Most of the Sebastian area's February 2025 rain came in one storm: 4.79 inches fell on February 24 and 25, 2025, and the month had 3 days with an inch or more against a normal of 0.5 (February 2025 report). The warmest day reached 86°F on February 13, and the coolest morning was 45°F on February 21.

Fog was the other February 2025 story at Vero Beach, the station that stands in for Sebastian. It was recorded on 21 days, and on 10 of them visibility dropped to a quarter mile or less. The top gust of the month, 38 mph, came from the east on February 25, during the same rain event.

Read together, the two reports show how far a single February can stray from the Sebastian normals. Average highs at Vero Beach ran 78.9°F in February 2025 and 73.3°F in February 2026, a difference of 5.6 degrees, and average lows ran 59.4°F and 47.7°F, a difference of 11.7 degrees. The 1991 to 2020 normals sit between them at 75.6°F and 54.5°F.

February severe weather near Sebastian comes with strong winter fronts, and NWS Melbourne's storm survey list includes several February tornado and hail events in east central Florida.

The best known is the Central Florida tornado outbreak of February 22 and 23, 1998. NWS Melbourne also lists the Groundhog Day tornado outbreak of February 2, 2007, an F1 tornado in Palm Bay on February 27, 2005, an EF0 tornado near the Brevard County coast on February 12, 2008, and large hail in Martin and southeast St. Lucie counties on February 24, 2010 (NWS Melbourne storm surveys). Sebastian sits between those counties.

Lightning stays sparse in February around Sebastian. NWS Melbourne estimates about 81 cloud to ground strikes in a typical February in Brevard County, and its climatology says February changes little from January because activity is still driven by mid latitude disturbances (NWS Melbourne lightning statistics; NWS Melbourne lightning climatology).

The NWS Melbourne dry season outlook issued September 30, 2026 groups February with March and April as its second forecast period, and its headline points to increased potential for well above normal rainfall and severe weather through April 2027 across central Florida, Sebastian included (NWS Melbourne dry season outlook).
