10/6/2018 Colors of tide XTide graphs changed to emphasize that they were upgraded. See next note. Comments welcome. 10/4/2018 I have fixed XTide and updated the harmonic files. There were some name changes so you might have to click EDIT to find the new station name. |

Sea breeze over SE florida metro terminals as of 18z, and should move through inland sites by 20z, whereas gulf seabreeze should be well inland of kapf this afternoon. Patchy fog from about 09z-13z mainly over interior peninsula but could affect ktmb and kapf with brief MVFR conditions.VFR and SW wind 8-10 knots expected for Saturday. Prev discussion issued 943 am est Fri feb 15 2019 update... a few showers have been affecting parts of metro broward and palm beach counties as well as the gulf stream waters this morning caused by convergence of overnight land breeze and light ne-e wind over the atlantic. For this reason, added in a slight chance of showers for coastal SE florida and the atlantic marine zones. These showers should dissipate this afternoon as the sea breeze circulation diminishes the convergence over the water. Inland- penetrating sea breezes along both coasts this afternoon will stay generally 10 mph or less, and with low level moisture remaining very shallow, any showers that manage to develop along the sea breezes will be meager and insignificant. Temperatures should reach 80 degrees over most areas away from the coasts this afternoon, with lower 80s over the southern everglades. Prev discussion... Issued 642 am est Fri feb 15 2019 aviation... vfr will prevail under high pressure. A few mostly light showers and associated bkn ceilings around 2,500 ft over the near-shore atlantic waters this morning should have little to no impact on terminals. Patchy light fog over the interior peninsula will burn off by 14z. Light wind will turn to seabreezes 8-10 knots along the atlantic and gulf coasts from about 16z-00z, then back to light and variable after 00z. Prev discussion... Issued 232 am est Fri feb 15 2019 discussion... high pressure governing across the sunshine state, in conjunction with primarily zonal flow in the mid-levels, will keep conditions |
mostly dry for Friday and throughout the weekend. The 15 00z sounding shows a pwat value of 0.76 inches which falls a hair below average for this time of year, further supporting a dry and pleasant day across south florida; however, a shower or two can't be ruled out completely in the atlantic as Wednesday's cold front has stalled over the bahamas. Additionally, models are hinting at a gulf breeze setting up this afternoon, but showers are not anticipated. For this morning, high clouds will continue to stream in before sunrise, limiting radiational cooling. So despite light to calm winds, the lack of radiational cooling and inadequate low level moisture will ultimately suppress widespread fog development. Any fog that does somehow manage to make an appearance (which would be near the gulf coast and western interior) will stay quite shallow patchy and short lived. Temperatures today will climb into the upper 70s to lower 80s, just hovering near seasonal average for this time of year. For the remainder of the forecast period, a series of systems will approach southeastern CONUS but will be unable to conquer us here in south florida thanks to that fairly persistent high pressure holding strong over the region. Eventually, rain chances will return early next week as winds shift from the S SE and low- level moisture returns. Warming temps and light flow may also allow the return of sea breeze activity. Marine... as high pressure builds back in for the weekend, conditions should remain below advisory thresholds with weakening winds and diminishing seas. High pressure will remain around the region through a good portion of the next week, allowing for pleasant boating conditions. Beach forecast... The rip current risk will diminish as the wind lightens over the next couple of days.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program. |
