Today on the water at Little Card Sound bridge
Today at Little Card Sound bridge: high tide at 4:11 AM (1.1 ft) and 5:11 PM (1.0 ft), low tide at 10:55 AM (0.5 ft) and 11:23 PM (0.6 ft). The National Weather Service forecast for today is slight chance showers and thunderstorms then chance showers and thunderstorms with E winds 13 to 17 mph, 84°F. Wind that strong can hold water in or push it out, so the real tide may run above or below these predictions. Sunrise is at 7:28 AM and sunset at 6:42 PM.

Where Little Card Sound bridge is
Little Card Sound bridge sits at 25.2883° N, 80.3700° W on the Florida Keys, where the Atlantic meets Florida Bay and the Gulf of Mexico, at North Key Largo, FL. The station here is a historical NOAA reference station: a gauge measured the tide at this spot from 1970 until 1975, and NOAA still publishes harmonic predictions from that record. There is no live reading here today. The closest gauge measuring live water level is Virginia Key, Biscayne Bay (NOAA 8723214), 33.3 mi away, and high and low water here run on average about 198 min later than there. The nearest weather station is Middle Key, FL, a shore station reporting wind and, at most sites, water temperature, 1.6 mi away.
The tide at Little Card Sound bridge
Little Card Sound bridge has a semidiurnal tide: two highs and two lows a day of about the same size, roughly 12 hours 25 minutes apart. This month's predictions average 1.9 high tides a day here. The mean range from lower low to higher high is 0.6 ft, and 0.5 ft between the average high and the average low, a small tide. For the water around it: The Keys sit on a tidal seam: the ocean side has two semidiurnal highs a day near 2 ft, while the bay side is smaller and more diurnal, so tides on opposite sides of one key can differ by hours.
About this station
- High tide reaches Little Card Sound bridge about 4.7 hours after the moon passes overhead. That lag is local, which is why high water does not line up with the moon.
- Highest water on record: 1.7 ft on Oct 18, 1970.
- Lowest on record: -0.8 ft on Feb 8, 1971.
Datum and source
Heights on this page are feet above mean lower low water (MLLW), the zero NOAA's nautical charts use for soundings. A predicted 0.0 ft low is the average of the lower low each day; a minus tide is water below chart datum, and a 2 ft high means 2 ft more water than the chart shows. NOAA fixes MLLW at Little Card Sound bridge from the 1983-2001 National Tidal Datum Epoch; mean higher high water is 0.6 ft above it and mean sea level 0.3 ft. The land survey datum NAVD88, the zero on topographic maps and flood maps, is 1.1 ft above MLLW here, so a water level on this page converts to NAVD88 by subtracting that amount. These datums are controlled from NOAA's Miami Beach, FL gauge. Source: NOAA CO-OPS station 8723534, established 1970, gauge removed 1975. The tide times and heights are NOAA's official harmonic predictions for this station; TidalMap republishes them daily and does not alter them.
