What is wind wave period?

What is wind wave period?

Wind-Wave Period (WWP) This is the peak period in seconds of the wind-waves.

What does a long period swell mean?

Swell period is a measure of that acquired momentum and it determines how far a swell will be able to travel in the open ocean. Short-period swell, (11 seconds or less) will usually decay within a few hundred miles, while long-period swell, (above 14 seconds), is capable of far greater journeys.

What does period mean in marine forecast?

In simpler terms, it’s how often the waves go up and down. The longer the period, the more time there is between the crests of the swells.

What is peak wave period?

The peak wave period (in seconds) is defined as the wave period associated with the most energetic waves in the total wave spectrum at a specific point. Peak wave periods are contoured by isolating different swell events with a single line—not contouring at a specific interval as in other forecast graphics.

Are 2 ft seas rough?

2 foot seas are great for fishing but can be rough for snorkeling. Its a little difficult to keep your head in the water when you are being bounced about by waves smacking you. You can check the weather report before setting out for the day, there’s usually a NOAA weather station on TV in the keys.

What is a bad wave period?

1-5 seconds: Local wind swells with bumpy and disordered waves. Poor surfing conditions; 6-8 seconds: Regional and local wind swells with average surfing conditions. Offshore winds might get it better; 8-10 seconds: Medium-distance swells improve the local surfing conditions.

What do wave seconds mean?

swell period
Page 1. Dominant Wave Period. The dominant wave period (in seconds) is a wave period associated with highest energetic waves at a specific point or area in the total wave spectrum and is always either the swell period or the wind- wave period. Dominant wave period is also known as the “peak” period.

What is zero up crossing period?

… are several simpler measures of wave period that are commonly used: the peak period, T p , which is measured as the average time between wave crests; the zero-crossing period, T Z, which is the inverse of the average number of times that the ocean level moves up across the mean water level per second; and the power …

What size waves can a boat handle?

A rule of thumb is 1/3 of your boat length is what your boat can reasonably handle. Obviously, with seamanship, you can take more but the math is against you. Think a boat a boat balanced on a wave 50% of the length. The boat can go down at a 45% angle.

What size boat do I need to go offshore?

How big of a boat do I need to fish offshore? You can fish offshore in a boat as small as 10 feet, although it’s best to have a boat at least 15 feet long for safety and efficiency when fishing offshore. Boats up to 30 or 40 feet may be appropriate for some kinds of offshore fishing.
