Marine Weather and Tide Forecast for Biscayne Park, FL

LONG TERM
(Sunday night through Friday)
Issued at 1253 AM EDT Sat May 17 2025

Deep-layer ridging and and dry weather will prevail across South Florida through the end of the weekend and into much of the upcoming work-week. The atmospheric column will remain quite dry during this period as dry air rotates anticyclonically around the surface ridge axis situated across the western Atlantic waters. NASA's/GMAO Dust Aerosol Optical Thickness model even hints at the periphery of a saharan dust plume arriving across South Florida during the early to middle portion of next week. However, the main implication of stout ridging directly overhead will be very light mid to upper level flow aloft and above average temperatures. Given the lack of cloud cover and subsidence aloft, temperatures will be on the toasty side with values several degrees above average across the area. Across inland areas, afternoon temperatures will peak into the mid to upper 90s each with temperatures in the upper 80s to low 90s across coastal locations. The foci of hottest afternoon temperatures may pivot by the middle of the work week, switching from southwest florida to southeastern florida as surface flow veers ahead of a weak boundary during the mid to late week period. There won't be much respite overnight as temperatures along the coast will still remain on the warmer side with lows in the middle to upper 70s along the east coast of South Florida.

With a lack of cloud cover and surface humidity, apparent temperatures (feels-like temperatures) will reach 100-105 degrees each afternoon. While just below lower bounds of heat advisory thresholds, prolonged exposure outdoors could impact vulnerable individuals. Sheltered areas exposed to these temperatures without climate control (parked cars) could become deadly for children and pets. Always look before you lock!

By mid week, a mid-level trough propagating across the Ohio River Valley and Great Lakes region will drag an attendant surface low and boundary eastward across the Mid-Atlantic and northeastern United States. This boundary is then forecast to arrive across our region mid-to-late week, bringing a deeper pool of low-level boundary moisture. This extra moisture could provide enough instability to spark up higher rain chances on Thursday and Friday. However, uncertainty remains regarding the evolution of this boundary as well as if any upper level synoptic support will arrive in tandem with this feature as the upper level low appears to be displaced well to the north at this time.

AVIATION
(06Z TAFS)
Issued at 125 AM EDT Sat May 17 2025

VFR conditions will prevail throughout the forecast period. Light and variable winds through the overnight hours will increase out of the SSE after 15z to around 10 kts. At KAPF, winds will increase out of the SW after 17z and become more westerly as the afternoon progresses due to the Gulf breeze pushing inland.

MARINE
Issued at 1253 AM EDT Sat May 17 2025

A gentle to occasionally moderate south southeasterly wind flow will remain in place through the upcoming weekend and into early next week across most of the local waters. The exception to this will be over the Gulf waters where winds will shift and become west southwest each afternoon as a Gulf breeze develops. Seas across the Atlantic and Gulf waters will remain at 2 feet or less through the weekend and into the early portion of the week.
