How hot is June in Palm Bay and Melbourne?
A typical June afternoon reaches 88.1 degrees at Melbourne International Airport (KMLB), the 1991 to 2020 normal in the NWS Melbourne monthly climate report.
The National Weather Service forecast page for Palm Bay shows current conditions from Melbourne International Airport (KMLB) (NWS Palm Bay forecast), so the June figures here come from that airport station. Its normals appear in the NWS Melbourne report for June 2026, which states a climate normal period of 1991 to 2020 (NWS Melbourne climate report, June 2026).
| Measure | June normal at KMLB |
|---|---|
| Average high | 88.1 |
| Average low | 73.1 |
| Mean | 80.6 |
| Rain | 7.10 |
| Days at 90 F or above | 11.5 |
| Days with 0.01 inch or more | 13.9 |
| Days with 0.10 inch or more | 9.6 |
| Days with 0.50 inch or more | 4.8 |
| Days with 1.00 inch or more | 2.6 |
June is the warm up for the hottest stretch of the year at the airport. Its 11.5 normal days of 90 degrees or more climb to 16.7 in July and 18.2 in August, by the NWS Melbourne reports for those months (NWS Melbourne climate report, July 2026) (NWS Melbourne climate report, August 2026).
No June at the airport has been hotter than 1998, which hit 101 degrees twice, on June 6 and June 14; the June low mark is 55 degrees, from June 2, 1984, in the NWS Melbourne climate record that runs from 1939 (NWS Melbourne climate report, June 2026).
When does the rainy season start in South Brevard?
NWS Melbourne puts the median start of the wet season at Melbourne on May 28, so in a median year the summer rainy pattern there is only a few days old when June begins.
The onset study by the NWS Melbourne office lists May 26 for Vero Beach and May 25 for Fort Pierce (NWS Melbourne wet and dry season onset). Each date is a median for 1950 to the present, so half of the years at Melbourne start earlier than May 28 and half start later.
Once it starts, the wet season dominates the year. A 22 year study of one north Melbourne rainfall station by NWS Melbourne measured a wet season of 138 days, about four and a half months, holding 64 percent of the yearly rain in 38 percent of the calendar (NWS Melbourne wet season statistics).
June outrains July and August at KMLB but trails September. Its 7.10 inch normal compares with 6.50 inches for July, 6.67 for August and 7.63 for September in the NWS Melbourne monthly reports (July report) (August report) (September report). An average June at the airport brings 9.6 days with a tenth of an inch or more, 4.8 days with half an inch and 2.6 days with an inch or more (NWS Melbourne climate report, June 2026).
June rain at KMLB swings widely from one year to the next. The record June total there is 15.98 inches, from 1966, and the driest June brought 0.16 inches, in 1998, the same June that set the 101 degree mark; June 2025 collected 3.53 inches, under half the normal (NWS Melbourne climate report, June 2026).
How much lightning strikes in June around Palm Bay?
Lightning in the county that holds Palm Bay, Malabar, Micco and Barefoot Bay jumps from about 838 strikes in May to about 4,398 in June, by the NWS Melbourne monthly estimate for Brevard County.
That is a rise of a little more than five times (4,398 divided by 838 is about 5.2), and the June figure for Brevard County is topped only by July and August, at about 5,707 and 6,676 strikes (NWS Melbourne lightning facts and figures).
The NWS Melbourne lightning climatology gives the reason. During the month of June the flash rates over the peninsula begin to dominate, because sea breezes form along both the east and west coasts and then collide over the interior (NWS Melbourne Florida lightning climatology). Melbourne International Airport logged thunderstorms on 18 days in June 2026 (NWS Melbourne climate report, June 2026).
Lightning tops the NWS Melbourne tally of Florida weather deaths for 1959 to 1993, at 53.1 percent, and the toll is heavy in the county that includes Palm Bay and Grant-Valkaria. The office counts 25 lightning deaths and 80 injuries in Brevard County from 1959 to 2007, the highest totals of the ten east central Florida counties in its table, ahead of Orange County with 16 deaths and 76 injuries (NWS Melbourne lightning casualty table).
One June case in the NWS Melbourne record sits on a road South Brevard drivers use daily. On June 9, 1978, lightning killed a 21 year old man and injured his brother while they worked on their car on I-95 south of the Valkaria exit (NWS Melbourne June hazardous weather history).
How did June 2026 compare with normal at Melbourne?
June 2026 was warm and wet at Melbourne International Airport, averaging 81.8 degrees, 1.2 above normal, which NWS Melbourne ranked the 8th warmest June there, tied with 2016.
The ranking comes from the NWS Melbourne summary for the month (NWS Melbourne June 2026 temperature rankings). The office also noted that a rare late season cold front moved through early in the month before much of June turned hot and humid (NWS Melbourne June 2026 temperature summary). The lowest reading at KMLB was 68 degrees, on June 8 (NWS Melbourne climate report, June 2026).
| Measure | June 2026 | Normal | June 2025 |
|---|---|---|---|
| Average high (F) | 88.9 | 88.1 | 88.5 |
| Average low (F) | 74.6 | 73.1 | 74.5 |
| Mean (F) | 81.8 | 80.6 | 81.5 |
| Days at 90 F or above | 14 | 11.5 | 9 |
| Days with 0.10 inch or more | 14 | 9.6 | 7 |
| Days with 0.50 inch or more | 8 | 4.8 | 3 |
Rain favored the immediate coast. NWS Melbourne reported June totals of 6 to 11 inches there, near to slightly above normal, while totals of around 2 to 6 inches left much of the region below normal (NWS Melbourne June 2026 rainfall summary). Melbourne collected 8.44 inches, 1.34 above its 7.10 inch normal, Titusville 10.73 inches and Vero Beach 6.79 inches (NWS Melbourne June 2026 rainfall table).
June 14 stood out at Melbourne International Airport, with both the greatest 24 hour rain total of the month, 1.52 inches, and the strongest gust, 54 mph from 170 degrees, in the KMLB report for June 2026 (NWS Melbourne climate report, June 2026). The hottest reading was 95 degrees on June 17, and fog was reported on 13 days.

Is June an active hurricane month for Palm Bay and Micco?
The Atlantic hurricane season opens on June 1, but the National Hurricane Center places the first named storm of an average season in mid to late June and the season peak on September 10, well after June for Palm Bay and Micco.
The National Hurricane Center climatology adds that tropical cyclone activity sometimes occurs before and after the official dates, and that the first hurricane of an average season tends to form in early to mid August (National Hurricane Center climatology). The same page puts most activity between mid August and mid October, so June opens the season for Malabar, Grant-Valkaria and Barefoot Bay rather than marking its busiest stretch.
Storms that have struck Palm Bay, Micco and Barefoot Bay in past years are covered on the Digital Towns South Brevard hurricane history page, at /florida/south-brevard/disasters/hurricane-history/, so this page keeps to June climate.
