Marine Weather and Tide Forecast for North Miami Beach, FL

LONG TERM
(Friday night through next Wednesday)
Issued at 245 PM EDT Thu May 22 2025

The aforementioned frontal boundary will be rapidly weakening over the Florida Keys late on Friday as its parent trough moves into the western Atlantic waters. However the residual moisture associated with the decaying front will remain in place across the region. This will allow for both the Atlantic and Gulf sea-breezes to propagate inland with the greatest chance for afternoon showers and storms across inland locales each afternoon through the weekend. 500mb temperatures will remain on the cooler side between -8 and -10 C at times which will keep lapse rates on the steeper side and could support a few storms on the stronger side. Heavy rainfall, locally gusty winds and frequent lightning is all on the table within storms that do develop. Sharp fluctuations and gradients in afternoon temperatures are indeed possible as shower and thunderstorm activity will act to knock down temperatures from their diurnal peaks.

The next mid-level impulse will be pushing eastward across the Central United states early next week and its associated frontal boundary will be approaching the Florida peninsula be the middle of next week. Similar pattern is expected through early next week as southeasterly wind flow is maintained. This will lead to a continuation of seabreeze thunderstorms across inland and southwest portions of the area each afternoon. 500mb temperatures will warm, which should keep the threat of stronger activity on the lower side. As the next front approaches from the north, surface flow will begin to slowly veer towards the south towards the end of the period and end of the week.



AVIATION
(18Z TAFS)
Issued at 1239 PM EDT Thu May 22 2025

Periods of MVFR/IFR conditions could be possible late this afternoon as a front approaches and SCT SHRA/TSRA impact the terminals. Although TEMPOs were included in this cycle, short- fuse amendments could be needed as conditions evolve.
Northwesterly winds prevail, but the East Coast sea breeze will develop and move inland early this afternoon. Dry weather overnight with light and variable winds, but chances for SHRA/TSRA return early on Friday, with vis/cig reductions once again possible.

MARINE
Issued at 1239 PM EDT Thu May 22 2025

Mostly benign marine conditions will persist through the remainder of the work week with light winds and seas 2 ft or less. Showers and storms will be possible across the Lake Okeechobee and nearshore Atlantic waters today and once again on Friday afternoon with the potential of locally higher winds and waves occurring.
