April Weather in South Brevard, Florida

Normal April afternoons in South Brevard reach 80.9°F at Melbourne International Airport and 82.8°F at the Palm Bay cooperative station, with nights at 62.8°F and 60.0°F, under NOAA's 1991 to 2020 normals.

The airport record, station USW00012838, is the one NWS Melbourne uses in its monthly climate reports for Melbourne. Its April mean is 71.8°F, and the normal gap between afternoon and early morning is 18.0 degrees (NCEI monthly normals, Melbourne airport).

The Palm Bay cooperative station, USC00086761, has almost the same April mean, 71.4°F, but a much wider daily swing of 22.8 degrees. Its afternoons run 1.9 degrees warmer than the airport's and its mornings 2.8 degrees cooler (NCEI monthly normals, Palm Bay), on the same 1991 to 2020 basis.

Ninety degree afternoons are uncommon in April but not rare in Palm Bay. The cooperative station averages 4.4 April days at 90°F or hotter, against 1.5 at Melbourne International Airport, and neither record has a normal April night below 40°F. Nights under 50°F average 1.6 a month at the airport and 1.3 at the Palm Bay station (NCEI, Palm Bay; NCEI, Melbourne airport).

For Micco and Barefoot Bay, at the Indian River County line, a NOAA normals station to the south is the Vero Beach airport, station USW00012843. Its April normals are 81.9°F by day, 62.4°F by night and 3.06 inches of rain (NCEI monthly normals, Vero Beach), close to the Melbourne figures but slightly wetter.

South Brevard gains about four degrees of afternoon warmth through April, as the Melbourne airport normal high climbs from 78.8°F on April 1 to 83.0°F on April 30 and the normal low from 60.0°F to 65.6°F.

Those are NOAA daily normals for Melbourne International Airport (NCEI daily normals, Melbourne airport). The midpoint of the month, April 15, carries a normal of 80.8°F and 62.7°F at the Melbourne airport, the observation station on the NWS forecast page for Malabar.

The Palm Bay cooperative station climbs on a similar slope from a cooler start. Its daily normal high is 80.5°F on April 1 and 84.9°F on April 30, and its normal low rises from 56.6°F to 63.1°F, a gain of 6.5 degrees in the morning readings (NCEI daily normals, Palm Bay).

Mornings warm faster than afternoons at both South Brevard stations. At the Melbourne airport the normal low gains 5.6 degrees between April 1 and April 30 while the normal high gains 4.2, so the daily range narrows as the month goes on in Palm Bay, Malabar and Grant-Valkaria.

Air conditioning season is already under way by April along the Indian River Lagoon. NWS Melbourne lists a normal of 218 cooling degree days for April at the Melbourne airport against 12 heating degree days (NWS Melbourne April 2026 climate report), and April 2026 ran to 284 cooling degree days.

April rain in South Brevard normally totals 2.29 inches at Melbourne International Airport and 2.81 inches at the Palm Bay cooperative station, but single Aprils at Melbourne have ranged from 0.01 inches to 8.15 inches.

The extremes come from the NWS Melbourne record that starts in 1939: the wettest April measured 8.15 inches in 1951 and the driest 0.01 inches in 1987 (NWS Melbourne April 2026 climate report). The largest single April day listed in the April 2023 report for Melbourne is 4.46 inches, on April 1, 2022 (NWS Melbourne April 2023 climate report).

NOAA's percentiles show how uneven the month is at the Melbourne airport. One April in four ends below 1.37 inches and one in four above 2.96 inches, and a normal April brings 3.8 days with a tenth of an inch or more but only 0.4 days with a full inch (NCEI monthly normals).

April closes Central Florida's dry season, which NWS Melbourne defines as November through April. The current outlook covers November 1, 2026 to April 30, 2027, was issued September 30, 2026, and carries the office headline Increased Potential for Well Above Normal Rainfall and Severe Weather (NWS Melbourne dry season forecast).

NWS Melbourne's lightning climatology describes April flash densities as rising over the peninsula, with sea breeze forcing beginning along coastal sections, and notes that April is the driest month of the year for Florida as a whole (NWS Melbourne lightning climatology). That coastal strip includes Palm Bay, Malabar and Barefoot Bay.

The last four Aprils at Melbourne International Airport ran from a 0.34 inch dry month in 2025 to a 4.72 inch wet month in 2023, and every one except 2024 averaged warmer nights than normal.

April 2023 was the wet and stormy one. The Melbourne airport recorded rain on 18 days, 11 thunderstorm days and 1 day with hail, with average highs of 83.5°F and lows of 68.1°F (NWS Melbourne April 2023 report). That report still compared the month with older normals of 82.3°F and 63.9°F; the reports from April 2024 on use 80.9°F and 62.8°F, so departures for Palm Bay readers are not directly comparable across those years.

April 2024 was the only month of the four with nights below normal at Melbourne. Lows averaged 62.2°F, 0.6 degrees under the normal, and the month dipped to 50°F on April 14 after reaching 91°F on April 11 (NWS Melbourne April 2024 report).

April 2025 was the dry outlier for Palm Bay and the Melbourne airport. The station measured 0.34 inches, 1.95 inches below normal, with rain on only 2 days, and the report counted 23 fair days and a single thunderstorm day (NWS Melbourne April 2025 report).

April 2026 reversed that at Melbourne International Airport. It collected 4.14 inches, 1.85 above normal, including 2.41 inches in the 24 hours from April 8 to April 9, and its average low of 67.8°F ran 5.0 degrees above normal (NWS Melbourne April 2026 report).

An EF-0 tornado that NWS Melbourne surveyed in Micco on April 16, 2023 brought peak winds estimated at 65 to 75 mph to South Brevard.

The survey placed the touchdown at 5:36 p.m. in the River Groves mobile home community in Micco, with a path of about 0.5 miles and a maximum width of about 100 yards. Brevard County Emergency Management counted 25 to 30 structures with at least minor damage there, and the storm went on across U.S. 1 into the Indian River Lagoon near the Sebastian River Marina (NWS Melbourne damage survey, April 17, 2023).

Strong gusts recur in April at the Melbourne airport, which sits north of Palm Bay. The peak was 58 mph from 300 degrees on April 27, 2023, 48 mph from 250 degrees on April 11, 2024, and 50 mph from 040 degrees on April 7, 2026 (April 2023 report; April 2024 report; April 2026 report).

April 2026 also brought 5 thunderstorm days and 5 days of heavy rain at Melbourne, along with fog on 7 days (NWS Melbourne April 2026 report). In April 2023 the airport logged fog on 11 days, 2 of them with visibility at a quarter mile or less (NWS Melbourne April 2023 report).

The National Weather Service ties its point forecasts for Barefoot Bay and Grant-Valkaria to Sebastian Municipal Airport (KX26) and its Malabar forecast to Melbourne International Airport (KMLB), so readings for the southern towns come from across the county line.

The forecast page for a point in Barefoot Bay lists current conditions at Sebastian Municipal Airport, at 27.81 N and 80.5 W (NWS point forecast, Barefoot Bay), and a point in Grant-Valkaria returns the same airport (NWS point forecast, Grant-Valkaria). A point in Malabar shows Melbourne International Airport at 28.1 N and 80.64 W (NWS point forecast, Malabar).

No NOAA normals from the Sebastian airport are used on this page. April averages for Micco, Barefoot Bay and Grant-Valkaria are given instead from the Palm Bay cooperative station and the Melbourne airport to the north and the Vero Beach airport to the south, with the station named on every figure.

The April records at Melbourne date to 1939. The record high is 97°F, reached on April 25, 1967 and again on April 15, 1999, and the record low is 35°F on April 8, 1971 (NWS Melbourne April 2026 report). The April 2023 report lists the hottest April on record at Melbourne as 2015, with a 77.1°F mean, and the coldest as 1987, at 65.7°F (NWS Melbourne April 2023 report).
