Paddleboarding Weather Guide: Wind, Tides & Forecasts for a Safe Trip

Paddleboarding is an incredible way to explore the water, but safety and enjoyment heavily depend on understanding wind conditions, tide charts, and weather forecasts. Checking these elements before heading out can prevent dangerous situations and help you make the most of your session.

In this guide, we’ll break down how to read wind patterns, tidal movements, and weather forecasts to ensure your paddleboarding adventure is safe and enjoyable.

Why Checking the Weather Before Paddleboarding is Essential and How to check it

Trip planning is key to safety and enjoyment. Use apps and online resources for information on tides, weather, and waterflows for your intended journey. Conditions can change quickly so always check the evening before, and again a few hours in advance of starting a paddle.

Take a copy of the map of your route and mark your journey on it, plus wind direction and strength during the trip. If paddling along the coast or on an estuary, ensure you know the size and direction of the swell and the times of high and low tides.

On river paddles, always check water levels. And if you get caught in thunder and lightning, exit the water as soon as possible and seek shelter at least 100m from the shoreline/water.

Here’s how to check the weather and water conditions before you paddle EVERY TIME.

Wind Conditions Can Make or Break Your Paddleboarding Experience

Wind is generally the top issue for paddlers and it’s vital to understand its direction and strength when planning a trip. Here are some basic facts:

• High winds can make paddling difficult or even push you offshore.
• Offshore winds (blowing away from shore) can be dangerous.
• Ideal wind speeds for paddleboarding are below 10 mph (16 km/h).

How to Check Wind Conditions for Paddleboarding

The best way to check the wind conditions is via an apps or website

Best Wind Apps & Websites for Paddleboarders

• Windy.com – gives a visualisation of the wind and colour-codes its strength. Paddlers need to choose days and times when the wind is coloured blue
• Other useful apps include Met Office, and Surfline.

Understanding Wind Speeds for Paddleboarding

Wind speeds of < 10mph (8.7 knots), or Beaufort scale 3, are best for paddleboarding. Above this winds can make paddling challenging.

Key Wind Directions to Know

In forecasts, wind direction is the direction the wind is coming from (not the direction it is heading). Paddling into a headwind (wind into your face) will significantly slow your progress, while a crosswind will affect your ability to paddle in a straight line and challenge your balance.

One way to overcome such winds is to kneel down and paddle with hands closer together towards the blade of the paddle. In more extreme circumstances, lie on the board, use the arms to paddle – much like surfers do to reach a break – and return to shelter and safety if the wind has picked up while on the water.

The best wind for paddlers is a tailwind (wind on your back), which will blow you in your desired direction of travel.

On rivers, be aware, too, that valleys and estuaries often funnel wind up or down them. Even if the wind is forecast for one direction, you may find that this changes according to locality. Always check conditions on the day with local paddle schools or RNLI lifeguard stations.

If paddleboarding on the coast, other important winds are Offshore winds (blows away from land), are the most serious for safety as they can propel you further out to sea. They blow off the land to the sea and are the cause of most paddleboard RNLI rescues. Tall buildings and cliffs can offer shelter from offshore winds, but the winds can strengthen as you paddle further from the shoreline.

Onshore winds (blow toward land), are generally safer for paddleboarders, but they can be choppy.

Clues for wind conditions can be gleaned from watching the surface of the water before you set out. If it’s calm in the bay but there are ripples 100m beyond and the water is even choppier further out, this indicates that there might be an offshore wind that’s hitting the water further out.

Wind over tide means the direction of the wind is opposite to the flow direction of the water. This creates wind chop, when cresting waves are created by local wind conditions, which is bad news for the paddler. In this instance, if you are paddling with a tailwind the water often looks flat in your direction of travel as you are surfing over the wave crests. However, when you turn around and paddle into the wind, you hit the wave crests and your journey will be wetter and choppier.

Wind with tide means wind and tide flow in the same direction. This can dampen down waves so is desirable when planning any estuary or coastal trip. Wind chop can also happen on any large expanse of water such as lakes and across estuaries, when waves suddenly pick up or drop as the wind changes strength. Early mornings and evenings are often the best time to paddle as the wind tends to drop naturally at these times.

Why Swell Forecasts Matter: Essential Tips for Safe Coastal Paddleboarding

After wind, swell is the next big issue for the coastal paddler. When wind from a low- pressure system in the Atlantic transfers its energy to the ocean, ripples of water are created (known as swell). These move towards the UK, growing in size over days and breaking as waves on our shore.

Swell height, the height from the wave’s crest to the trough, greater than 0.3–0.6m (1–2 ft) will be challenging for most paddlers. Swell direction is the direction of travel. So, if a SW swell hits a SW-facing beach, the waves will break directly on the beach and may make launching/landing tricky. If a SW swell passes an E-facing beach, the waves are less likely to have an impact – making it potentially a safer or more comfortable spot to launch/land from.

Swell interval can offer a good indication of conditions. An interval greater than 10 seconds between swells indicates that the swell is consistent and coming from the Atlantic. Intervals less than this – say of 5 seconds – indicate that local wind conditions are influencing the swell and may change over the day. The paddler, therefore, needs to track wind conditions to anticipate changes in swell and direction, especially when launching and landing.

Clapotis is the name given to waves that rebound from vertical faces, such as cliffs and breakwaters, back into the incoming wave. This produces a jumbled, spikey effect on the water’s surface, which can make balancing more difficult for the paddler. Paddling a distance away from these vertical features will help avoid the chaotic water.

Why Checking Tides is Essential for Safe Paddleboarding in Coastal & Estuary Waters

Tides impact your route & water depth. Low tides may expose sandbars and rocks. Strong tidal currents can make paddling challenging (or easy depending on your direction of travel). Understanding slack tide (the period between high and low tide) is ideal for calmer paddling.

How to Read Tide Charts for Paddleboarding

There are plenty of tide apps and websites available. We always use the BBC tide tables.

A tide chart shows:

• High tide (HT) – Water at its highest level.
• Low tide (LT) – Water at its lowest level.
• Tidal range – The difference in height between high and low tide.

The Best Tide Conditions for Paddleboarding

• Slack tide (just after high or low tide) is the time the tide is changing and is the most ideal tide state for paddleboarders.
• Avoid strong tidal currents in areas with big tidal swings.
• Be cautious of shallow waters at low tide, which may expose hazards.

When planning a trip, always check tide tables for tide times and height, and whether it’s a spring or neap in specific locations for any day of the year. Paper copies of local tide tables are often on sale in coastal villages and towns, and the BBC provides free online 5-day tide tables.

Most places on the UK coast experience two flood tides resulting in high tide/water on a beach and two ebb tides resulting in low tide/water every day (or every 24hr 50min period, to be precise), and these times are shown in the tables. The period between high and low tide is around six hours. In some locations, access to the water is only possible around high tide (due to crossing muds etc at low tide).

Tide tables also include symbols to represent moon phases, which affect tides. A full or new moon has the largest impact and generates a spring tide, resulting in water rising higher up the beach at high tide and ebbing further away at low tide. Paddling to the head of tidal creeks and estuaries is often only possible on spring tides.

On neap tides, which occur at the first and third quarter of the monthly lunar cycle (represented by a crescent symbol on tide tables), the tide doesn’t reach as high up the beach or ebb out as far. Considerably higher volumes of water move between high and low tides on spring tides compared to neaps. For this reason, neap tides are preferable for paddles along the coast or at the mouth of estuaries.

Neap and spring tides also affect the height of high and low water (given in metres next to tide times in tables). For some paddles, a trip may only be feasible when the tide is deep enough at high water.

Technically speaking, a spring tide occurs on the day of the month when the tide is at its highest, which is often 1-2 days after a full and new moon. However, in this book “springs or neaps” refers to the period 2 days before and after a spring or neap tide when the paddler can maximise their benefits.

Understanding the direction of water flow along coastlines and estuaries is important for planning trips. For example, for most paddles along the coastline of South East England, the water flows laterally west to east on the flood tide and reverses on the ebb. However, the tidal flows of the Thames estuary go from east to west; and on the Essex coastline they go from south to north. Understanding this direction of flow will assist you when choosing direction and timing so that you can choose tidal assistance (paddling with the tide, not against it).

Also, be aware that some rivers can be tidal for up to 20-30 miles inland, so always seek local advice from a local SUP school or the RNLI.

The speed of tidal flow depends on the stage of the tidal cycle. At high tide and low tide, flows tend to be at their lowest – this period is often referred to as slack water and it’s generally a good time to paddle.

As the tide cycle shifts from high to low tide, the ebbing tide initially flows slowly and then builds up speed as it approaches the mid-ebb tide, which has the fastest flow. After this, the flow slows again towards low tide. The same is true for flood tides.

For the beginner, the mid-ebb or mid-flood is one to avoid, especially around headlands or over reefs and ledges where turbulence and challenging conditions can occur. Mid-ebb and mid-flood tides on spring tides will be even more turbulent and challenging, compared to the same on neaps when less water is moving around. For a competent paddler, these mid-tides offer a key time to make good progress on the longer trips detailed in this book.

Rip currents

As waves break on a beach a rip current can form where water returns through a narrow stream. Rip currents are always very localised and mostly occur near river mouths, sandbars, and jetties that help funnel the returning water back out to sea. Generally, the bigger the waves, the stronger the rip current. From the shore, if you see a gap in the line of waves where the waves do not seem to break, it’s most likely a rip current.

For the experienced paddler, a rip current can be used to navigate through the breaking waves at the beginning/end of a paddle. Obviously, for a beach swimmer a rip current should always be avoided.

Tides and flows are complex. For in-depth information, refer www.marine-education.co.uk/free-tutorials/tide-tutorials/ and check with a local paddle instructor.

Understanding river conditions for planning a safe paddleboarding trip

Be mindful of water flow on rivers and canals, as currents and fast-moving water may present significant hazards. Recent heavy rain as well as sluices, weirs, bridges, and locks en route can all increase water flow speed. Plan ahead, and once you get to the river, check for turbulence on the surface – a strong clue that the flow is quick. Anything over 4 knots (nearly 5mph/very brisk walking speed) is inadvisable to enter.

A typical river will have large variations in flow depending on the shape of the riverbed (including obstacles), whether the river is getting deeper or shallower, and whether it is straight or meandering.

Generally, the sections that move slower are near the bank, especially along the inside edge of a curve. When heading upstream, paddling will be easier closer to the bank. At the bank you are also likely to encounter eddy currents where the flow is generally upstream; this counter-flow can help the paddler.

The fastest flow is generally on the surface in the middle of a river. Near the riverbed, water flow will be slowed by drag on sand and rocks, just as it is in the shallow water near the bank. This book is not intended to cover white-water sections of rivers; however, in certain low-water conditions, riffles – small rapids that often form across shallows – may be encountered.

Floodwater increases the speed of the flow and adds unexpected currents. Also, a multitude of dangers – from rocks and tree stumps to shopping trollies – can hide just under the surface, waiting to snag your fin.

Always check online for water-depth information at riverlevels.uk or  check-for-flooding.service.gov.uk/river-and-sea-levels and avoid the waterway if above normal levels. If water levels fall below 3ft (1m), always drop to your knees on the board to avoid falling into shallow water if you run aground. Increasingly, water boards discharge raw sewage into water courses during flood conditions, so check theriverstrust.org/sewage-map
