Marine Weather
In Miami we are graced with fantastic sub-tropical weather and diving conditions! This is due in part to the Gulf Stream current that runs northward along the east coast of Florida, bringing warm water and shaping Miami's climate to mirror the rest of the Caribbean. Certain places in the Caribbean have notoriously strong and unabating winds, causing notoriously rough diving conditions. The tradewinds that blow during winter months in Miami and the ocean swells that they typically bring are baffled by the nearby islands of the Bahamas, making our waters relatively calm. However, local gusts and squalls can make boat travel hazardous. Refer to the wind forecast below for a better idea of what the conditions will be like over the next few days.
Understanding a marine forecast is critical to safe boating.
Typical marine forecasts predict wind speed and direction, wave heights and periods, roughness of near shore waters, and significant weather. Marine forecasts cover large areas and the forecast elements are often given in ranges. The significant weather may not occur over the entire area or during the entire forecast period. The ranges represent average conditions over a period of time (usually 12 hours) and the actual conditions may be lower or higher than the forecast range. Boaters should plan for conditions above and below the predicted ranges.
Take particular note of any current advisories and warnings, including Small Craft Advisories, Gale or Storm Warnings which alert mariners to either high winds or waves occurring now or forecast to occur up to 24 hours from now. Special Marine Warnings are issued for sudden increase in winds to over 35 knots (40 mph), waterspouts (tornadoes over water), and hail of 3/4 inches or greater and indicate a more immediate threat. Marine weather statements bring attention to significant rapidly changing conditions on the water including increase in winds, thunderstorms, development of dense fog and even snow squalls or strong and gusty rain showers.
