Autumn Paddling – Changing Weather, Changing Waters

As the summer draws to a close and autumn edges in, our rivers and lakes begin to shift character. Cooler air, shorter days, and more unsettled weather can make for fantastic paddling conditions – but they also bring new challenges to be aware of.

Rivers – More Than Just Rising Levels

Rainfall is the biggest factor on rivers at this time of year. After long dry spells, the ground can’t absorb much water, so sudden downpours can cause river levels to rise quickly and dramatically. What was a gentle float one weekend might be fast-flowing white water the next.

It’s not just water levels to think about:

• Trees and debris – Autumn storms often bring branches or even whole trees into the water, creating blockages (strainers), or obstacles in channels. These can appear suddenly after heavy rain.

• Flowing water, currents and rapids – Increased flow can turn easy sections of river into technical rapids, demanding quicker decision-making and stronger paddling skills.

• Weirs – With more water, weirs become particularly hazardous. Recirculating hydraulics at their base can become much stronger and extremely dangerous. Even small weirs that look harmless in summer can turn into serious hazards. If doubt always get off the river in plenty of time and walk around.

• Changing channels – On braided or shallow rivers, rising water may open new routes or block existing ones. Familiar sections may look very different.

Open Water – Wind Rules the Day

On lakes, reservoirs, and estuaries, wind is often the most important factor in autumn. While water levels may remain stable, the conditions can shift rapidly depending on the weather system overhead.

Things to keep in mind:

• Wind direction – A tailwind might make the outward journey feel effortless, but that same wind will be against you on the way back, potentially doubling the effort and time required.

• Wave conditions – Even moderate winds can whip up choppy water, making balance and progress more challenging, especially on SUPs or open canoes.

• Landing points – Always identify possible landing or escape points around the lake or shoreline. Strong winds can make it difficult (or impossible) to return to your intended launch spot, so know where else you could safely get off the water.

• Exposure – Open water often has little shelter from the wind. Once you’re committed to a crossing, turning back may not be an easy option.

Key Considerations for Autumn Adventures

✅ - Never paddle alone – always head out with at least one other person.

✅ - Plan your route and share it with someone on land, including your expected return time.

✅ - Check the forecast for both wind and rainfall – and be prepared to adapt your plans.

✅ - Carry a fully charged mobile phone in a waterproof case.

✅ - Prepare your equipment for colder water and shorter days: extra layers, a head torch, and spare kit make all the difference.

✅ - Know the river levels before you go – particularly after rain.

✅- Be wind-aware on open water – plan for both the outward and return journey.

✅ - Always have a “Plan B” – know where you can get off the water safely if conditions change.

Autumn is a season of contrasts. The colours and crisp air can make for some of the best days on the water, but the risks can also increase quickly. With the right preparation and a healthy respect for the conditions, you can enjoy safe, rewarding paddling all season long.

Exploring our rivers, lakes, and coastlines outside of summer can make for some great adventures. If you’re unsure about conditions or simply want to build your confidence, seeking the guidance of a qualified coach or joining a guided trip is a brilliant way to get the most out of the experience.

For inspiration and practical advice, Paddle UK provides excellent online resources, from information on where to paddle to safety tips and preparation guides. With the right mindset and support, the off-season can open up a whole new side to paddling, one that’s every bit as enjoyable, and perhaps even more memorable, than the summer months.
