Skegs launched in 2014 with the aim of bringing useful water sports information together in one place. Our founder, Steve Midgley, had become weary of manually stitching different sources together to build up a picture of the local sailing conditions. Being a keen sailor and windsurfer in the South of England, he found that it was imperative to know not just the wind and weather forecasts but also what the tide would be doing.
At Skegs we understand that sailors, surfers and other water sports enthusiasts need to know about water conditions as much as the weather. The tide depth, direction of flow and surf conditions can be just as important as the wind, temperature and rain. So we draw on the best information sources available to present a comprehensive and easy-to-use forecast for users across the globe.
We've found a growing interest in our products from inland sailors and have expanded our coverage beyond the coasts. We can provide weather-only forecasts for any location on the globe, so if you can't find your favourite inland spot please tell us which location you'd like to see and we'll add it for you as soon as we're able.
How to Read Our Forecasts
We provide a 7-day forecast for each of the locations that we cover. The times shown are local to that location.
Tide is an indication of the height of the tide at a point measured by the hydrographic services. It should be read in conjunction with your experience of the local area to determine how it reflects the minimium tide depth needed for your equipment.
The direction of the tide is indicated by a graphic as follows:
|Tide depth is increasing (flood / tide coming in).|
|Tide depth is decreasing (ebb / tide going out).|
|The tide will reach a low ebb and start to come in (change from ebb to flood).|
|The tide will peak and start to go out (change from flood to ebb).|
Tide depth can be shown either in meters or in feet and inches.
Occasionally, a change in tide direction can be followed by a depth that appears to go the wrong way. For example, you may see a symbol at 8am that says the tide will begin to come in, yet the depth at 9am is still lower. This occurs when the actual tide change happens late in the window, such as at 8:50. The symbol aligns with 8am for ease of reading, but the depth is lower at 9am as it is closer to the low water mark.
No tidal information is shown for inland locations.
The moon phase shows each day's stage of the 28-day lunar cycle. Full moon and new moon produce spring tides, which are stronger than the neap tides found during the first and last quarters. Spring tides bring higher highs, lower lows and a more pronounced flow. You can find a good explanation of the relationship between the moon and tides in Deborah Byrd's blog post on EarthSky from June 2015. We indicate the moon phases as follows:
|New moon||First quarter||Full moon||Last quarter|
Wind and Gust indicate the speed and steadiness of the wind. Wind speeds can be shown in miles per hour (mph), kilometers per hour (kph), knots (kts) or the Beaufort scale (Bf).
Wind Direction indicates the bearing that the wind is blowing on. The arrow points in the direction that the wind is heading, while the text indicates the compass point that it is blowing from. Wikipedia has a good page that explains wind direction conventions in more detail.
Temperature reflects the air temperature and can be shown using either the celsius or Farenheit scales.
Cloud cover indicates the percentage of the sky obscured by cloud. The lower the number, the sunnier it should be.
Rain indicates the volume of precipitation expected in a one-hour period. Although we have opted to use the generic term of "rain", precipitation could also take the form of hail, sleet or snow. Please consider other factors such as temperature or whether your area is prone to thunder showers when planning your session. Rainfall can be shown using millimeters or inches.
Current shows the strength and prevailing direction of marine surface currents. The speed is shown using the same unit as the wind - kph, knots or mph (default). A good description of the relationship between currents and tides is available on Wikipedia.
Swell forecasts are available for many of our coastal locations and show the height of marine waves along with the mean direction of travel and the time in seconds between swells. The background colour's intensity indicates the swell height relative to the location's normal range. Deeper colours mean bigger waves, while lighter colours predict flatter water.
Barometric Pressure (shown as BP on the forecast) gives the level of atmospheric pressure, or the gravitational force of the air. Air pressure is a crude indicator of whether conditions are stable or likely to change. The value itself is fairly insignificant, what matters is the rate and direction of change. Generally, stormy conditions are associated with rapidly falling air pressure, while high steady values indicate clear skies with light winds.
The Overnight Summary is intended to give a sense of how the weather may affect conditions between the daily forecasts. For example, stormy winds overnight can whip up swell and chop, but would not otherwise be evident if the storm passes before daybreak. The wind factors shown are the minimum wind and maximum gusts. Temperature is the overnight low. Rainfall is the total forecast for the period.
Water temperature is a measure of the water surface temperature. We use the most recent 24-hours buoy and ship data combined with satellite geothermal imaging to provide the current average temperature value for each location.
A Note About Forecast Accuracy
Weather forecasters use a variety of instrumentation and data as a basis for constructing their forecasts. They then apply models to this data to provide a picture of what the weather is likely to do over a period of time. In most cases, short-term forecasts (up to two days) tend to be more accurate than longer-term ones. Of course, our forecasters don't control the weather, they simply try to read it. Sometimes they get it wrong due to other factors coming in to play that were not, or could not, be considered.
Tide predictions tend to be more reliable than weather forecasts as they are based primarily on the position of the moon, sun and Earth in relation to one another. These are stable factors that combine with the shape of the ocean basins and the swirl caused by Earth's rotation. This means that, for any coastal location on the planet, it is possible to predict with some degree of certainty when the tide will change direction and what the mean water depth will be at that point. However, there is still a degree of modelling needed to provide predictions between the high- and low-water marks, and geographical factors such as narrow channels may also influence the depth and strength of flow.
While we endeavour to provide you with the most accurate forecasts available, they are intended for recreational use only. Please take sensible precautions before going afloat and consider how you may respond should conditions not turn out as expected.

What Are Skegs Anyway?
Wikipedia defines a skeg, (skegg or skag) as a sternward extension of the keel of boats and ships which have a rudder mounted on the centre line. In more recent years, the name has been used for a fin on a surfboard that improves directional stability and to a moveable fin on a kayak which adjusts the boat's centre of lateral resistance (it moves the center of resistance relative to the center of effort). The term is also often used for the fin on water skis in the U.S. and for the tail bumpers of aircraft in the US Navy.
The word originates in the Scandinavian word for beard ("skegg" in Old Norse). In Icelandic the word remains skegg; in modern Norwegian Bokmål and Nynorsk it appears as skjegg; in Swedish it is skägg and in Danish, skæg. The Norwegian pronunciation of the letter combination "skj" is as in the English "sh".
The word is related to the English "shaggy". It also appears in the English place name Skegness - "beard point" - from the way in which a series of tombolos forms towards the nearby Gibraltar Point. Here the English pronunciation reflects a probable Danish origin, which pronounces the "sk" letter combination as an English speaker would expect.
