Weather in July in South Brevard, Florida

July has the warmest normal afternoon of the three summer months at Melbourne International Airport, 89.7 degrees, against 88.1 in June and 89.3 in August, under the 1991 to 2020 normals.

Palm Bay readers see airport data on their forecast: the Palm Bay point forecast from the National Weather Service lists current conditions at Melbourne International Airport (KMLB) (NWS Palm Bay forecast). The forecast point for Micco reads instead from Sebastian Municipal Airport (KX26) (NWS Micco forecast). The KMLB normals below are printed in the NWS Melbourne report for July 2026 (NWS Melbourne climate report, July 2026), and the June and August normal highs in the reports for those months (June 2026 report) (August 2026 report).

A normal July at KMLB brings 16.7 afternoons of 90 degrees or more, more than half the month, while the August normal high slips to 89.3 even as August keeps the warmer nights, with a normal low of 74.7 against 73.7 in July (NWS Melbourne climate report, August 2026).

The NWS Melbourne office on Croton Road notes in its station digest that summer temperatures often climb into the 90s, on 63 days a year (NWS Melbourne station digest). The hottest reading in the Melbourne record also came in July: 102 degrees on July 14, 1980, which stands as the July record at Melbourne International Airport and the all-time high in the digest.

The coolest July morning in the KMLB record was 60 degrees, on July 2, 1977, according to the NWS Melbourne monthly report, whose climate record period begins in 1939 (NWS Melbourne climate report, July 2026).

NWS Melbourne calls July the month for lightning over the state of Florida, when sea breezes from both coasts become well developed over the peninsula, and Brevard County, home to Palm Bay and Malabar, averages about 5,707 lightning strikes in the month.

The NWS Melbourne lightning climatology explains that warm coastal waters and near maximum sunshine let both sea breezes develop, and that the subtropical ridge axis puts the lightning maximum over the central peninsula (NWS Melbourne Florida lightning climatology). Along the southern part of the east coast the east coast sea breeze tends to move inland quickly, and as the day goes on the two sea breezes can collide over the central peninsula, the same page says. Those warm coastal waters are measurable: the NOAA NCEI coastal water temperature guide puts the July average at 83.2 degrees for Trident Pier, Port Canaveral, and 82.9 degrees offshore at the Canaveral buoy, 20 nautical miles out (NCEI coastal water temperature guide).

The Brevard County monthly lightning estimate climbs from about 4,398 strikes in June to about 5,707 in July (NWS Melbourne lightning facts and figures). The same page gives the Melbourne and Vero Beach coast 70 to 80 thunderstorm days, fewer than the 80 to 90 of interior Orlando.

Melbourne International Airport recorded thunderstorms on 17 days in July 2026, more than half the month, according to the NWS Melbourne report for KMLB. The month's strongest gust there, 47 mph from 160 degrees, came on July 28, and the highest sustained wind, 38 mph from 300 degrees, on July 13 (NWS Melbourne climate report, July 2026).

Melbourne International Airport averages 6.50 inches of rain in July under the 1991 to 2020 normal, with measurable rain on 14.4 days of the month.

No summer month at KMLB is a sure thing for rain. The KMLB record runs from 0.81 inches in July 1955 to 13.40 inches in July 1944, a spread of 12.59 inches (13.40 minus 0.81), according to the NWS Melbourne report for July 2026 (NWS Melbourne climate report, July 2026).

Wet days are frequent, but heavy ones are few. Melbourne International Airport averages 10.0 July days with 0.10 inch or more, 4.4 with 0.50 inch and 2.5 with an inch or more, by the 1991 to 2020 normals in the same KMLB report (NWS Melbourne July normals, KMLB).

Over a whole year, NWS Melbourne found that Melbourne receives measurable rainfall on 100 to 105 days, and that a north Melbourne gauge averaged 14 days a year with an inch or more for 1992 to 2013: 10 days with 1 to 2 inches and 4 days above 2 inches (NWS Melbourne wet season statistics).

The tropics are usually quiet in July. In an average Atlantic season the first hurricane tends to form in early to mid August, according to the National Hurricane Center climatology (National Hurricane Center climatology). The record of storms that reached Palm Bay, Micco or Barefoot Bay sits on the Digital Towns page /florida/south-brevard/disasters/hurricane-history/, not here.

July 2026 was hotter than normal at Melbourne International Airport: it averaged 83.4 degrees, 1.7 above normal, tied 2024 as the 10th warmest July there and brought 28 days of 90 degrees or more against a normal of 16.7.

The NWS Melbourne summary for July 2026 ranks Melbourne 10th warmest, tied with 2024, and Vero Beach also 10th warmest at 82.9 degrees (NWS Melbourne July 2026 temperature rankings). Departures from normal and the July 2025 values come from the KMLB monthly report (NWS Melbourne climate report, July 2026).

The steering pattern explains the rain map. NWS Melbourne wrote that the ridge axis of high pressure over the Atlantic often stayed south of the area, steering showers and storms across east central Florida, with amounts up to 9 to 13 inches along the Treasure Coast (NWS Melbourne July 2026 rainfall summary). Fort Pierce had 12.93 inches, its second wettest July on record, and Vero Beach 9.68 inches, its 10th wettest.

Melbourne itself landed almost exactly on normal, with 6.57 inches against 6.50, while Vero Beach ran 4.00 inches above its July normal and Titusville collected 9.62 inches against 6.77 (NWS Melbourne July 2026 rainfall table). At KMLB the wettest day was July 30, with 1.87 inches, the hottest reading was 95 degrees on July 28, and the coolest was 70 on July 14. All 31 days counted as fair under the report's sky cover tally.
