Vero Beach Seasons Month by Month

By the 1991 to 2020 normals for the Vero Beach airport station, January is the coolest month at 73.3 degrees by day and 52.2 at night, and August is the hottest and wettest at 90.6 degrees and 7.35 inches.

The figures come from the NOAA Regional Climate Centers ACIS service for station USW00012843, which ACIS names Vero Beach Intl AP and lists at an elevation of 19 feet (ACIS normal highs). In the ACIS documentation, the option normal=91 returns the NCEI 1991 to 2020 normal, the same 30 years the National Weather Service uses in its Vero Beach reports (ACIS Web Services documentation).

Read as seasons, the Vero Beach table splits cleanly. Winter (December to February) holds highs between 73.3 and 75.6 and lows between 52.2 and 56.1 (ACIS normal lows). Spring warms fast: the normal high climbs from 78.4 in March to 85.7 in May, a gain of 7.3 degrees in two months. Summer (June to September) is a plateau, with every month between 88.4 and 90.6 by day and between 72.2 and 73.6 at night, so the normal Vero Beach summer night never averages below 72 degrees. Fall gives the heat back in steps, from 84.8 in October to 79.3 in November.

The normal year at the airport totals 53.25 inches of rain (ACIS annual normal). February is the driest month at 2.20 inches and August the wettest at 7.35, more than three times as much (ACIS normal rainfall). The September figures in the table match the normals that NWS Melbourne printed in its September 2026 Vero Beach report, 88.4 and 73.4 degrees, which is a useful check that the two products describe the same station and period (NWS Melbourne September 2026 Vero Beach report).

Vero Beach gets about 60 percent of its normal rain from June through October because the Bermuda high steers where the Atlantic and Gulf sea breezes collide each summer day, a pattern NWS Melbourne calls the Florida Rain Machine.

Those five months add up to 32.16 inches of the 53.25-inch Vero Beach normal: 6.76 in June, 5.68 in July, 7.35 in August, 7.04 in September and 5.33 in October (ACIS normal rainfall). The NWS Melbourne explanation is that the position of the Bermuda high pressure ridge sets the low level wind and so decides where the two sea breezes meet each day, and that collision often produces storms with frequent lightning and heavy rain (NWS Melbourne, The Florida Rain Machine).

July is the odd month on the Vero Beach chart. Its 5.68 inches sits below both June and August, a dip that shows up in the 1991 to 2020 normals for the airport station even though the July normal high of 90.5 degrees is only 0.1 below August. The same NWS page notes that the start of the rainy season is fickle: in the changeable year of 1998 the true rainy season did not begin until the first week of July, while the typical start falls in the third or fourth week of May, and the page gives May 26 as the approximate start for Vero Beach (NWS Melbourne).

Thunder is the signature of that season. The NWS Melbourne annual report for Vero Beach counted 87 days with thunderstorms in 2025, and in September 2026 alone the airport logged 17 (NWS Melbourne 2025 Vero Beach summary). That September also had 3 days with an inch or more of rain against a normal of 1.9, and an average relative humidity of 79 percent (NWS Melbourne September 2026 summary).

The dry season at Vero Beach begins with the first cold front that brings drier air, on a median date of October 19, and from then until May most Vero Beach rain comes with passing fronts rather than afternoon storms.

NWS Melbourne dates the Vero Beach dry season to October 19 and the first reading below 50 degrees to November 13, both as median dates from a record that runs from 1950 to the present (NWS Melbourne wet and dry seasons). Its Rain Machine page adds the caution that first cool fronts are often short-lived: moisture can return after several dry days, and tropical systems can still bring significant rain through October and into November (NWS Melbourne). In the Vero Beach normals October still carries 5.33 inches while November drops to 2.91.

The cool half of the Vero Beach year is short on cold. In the 2025 annual summary the normal year has 400 heating degree days against 3,555 cooling degree days, so cooling degree days outnumber heating degree days nearly nine to one, and 2025 ran warmer still with 303 heating and 3,701 cooling degree days (NWS Melbourne 2025 Vero Beach summary). Dry season rain can still arrive in one burst: the wettest 24 hours at the airport in 2025 was 4.79 inches on February 24 and 25, in what is normally the driest month of the Vero Beach year.

Vero Beach ran about half a degree warmer than normal in 2025 and had fewer rainy days than usual, according to the NWS Melbourne annual climate summary for the airport station.

The 2025 summary, issued January 1, 2026, lists an average high of 83.2 against a normal of 82.7, an average low of 64.9 against 64.5 and a mean of 74.0 against 73.6 (NWS Melbourne 2025 Vero Beach climate summary). Days with at least a tenth of an inch of rain numbered 64, well short of the normal 76.1, and days with half an inch or more numbered 26 against 32.2. Days with an inch or more were right at normal, 16 against 15.7, so 2025 at Vero Beach had fewer wet days but kept its share of downpours.

The same report gives the texture of a Vero Beach year that the monthly table cannot. Average relative humidity was 75 percent, fog was reported on 169 days, and 246 days were classed as fair. The highest gust of the year was 54 mph from 280 degrees on July 10 (NWS Melbourne). The warm run has carried into 2026: by the end of September the airport had logged 3,215 cooling degree days since January 1, against a normal of 2,884 (NWS Melbourne September 2026 summary).

NWS Melbourne, the forecast office that reports Vero Beach climate, gives higher odds of a wetter and stormier than normal dry season from November 2026 through April 2027 because El Nino conditions have developed and a very strong event is forecast.

The office issued its Central Florida dry season forecast on September 30, 2026, for the period November 1, 2026 to April 30, 2027, with the next issuance planned for January 2027 (NWS Melbourne Dry Season Forecast). The outlook says El Nino conditions are strengthening, that the event is likely to be record breaking in intensity, and that this raises the probability of wetter than normal conditions across central Florida, with more seasonal storminess and a higher potential for severe weather, especially strong to violent tornadoes (NWS Melbourne 2026 to 2027 dry season outlook). It also says the rain should ease ongoing drought and lower wildfire potential, while raising the threat of heavy rain and river flooding, and that temperatures lean toward normal.

For Vero Beach the practical baseline is the normal that a wet winter would be measured against: 2.91 inches in November, 2.54 in December, 2.74 in January, 2.20 in February, 3.44 in March and 3.06 in April, or 16.89 inches over the six months (ACIS normal rainfall). The outlook gives a 90 percent chance of a very strong El Nino and a 75 percent chance of the strongest on record, with records back to 1950 (NWS Melbourne outlook). The forecast covers Florida climate divisions 3 and 4, so it is a regional signal for the Vero Beach area rather than a town forecast.

The Atlantic hurricane season, June 1 to November 30, lies mostly inside the Vero Beach wet season, and its September 10 peak falls in September, the second wettest month in the Vero Beach normals.

In the National Hurricane Center climatology the Atlantic season peaks on September 10 and is busiest from mid August to mid October (National Hurricane Center climatology). At the Vero Beach airport station, August (7.35 inches) and September (7.04) are the two wettest months of the 1991 to 2020 normals (ACIS normal rainfall). The NWS Melbourne Rain Machine page makes the related point that tropical systems keep rain going into October and November after the summer pattern fades (NWS Melbourne).

Storm preparation, evacuation zones and the record of past landfalls are covered in the Vero Beach hurricane season guide and the Vero Beach historical storm impacts guide; the weather hub for Vero Beach keeps the all-time records.
