Your kayaking outfit is likely to change depending on whether you are planning on going kayaking in the winter or summer months. In the summer months, the clothes you wear don't have to be anything special. The main thing to remember to keep with you would be rain-proof clothing such as a raincoat or other waterproof clothing, just in case the weather takes an unlikely turn for the worst. Similarly, although during the warmer seasons it is unlikely you will need a change of clothing, accidents can always happen, so if you want to be prepared, do carry an extra change if clothes with you. Clothes are more likely to dry off quickly in the heat, however, so getting wet may not be that big of a problem, especially if it's a fairly short kayaking trip. In contrast, dressing up for winter kayaking is a whole different ballgame due to the cold weather, and it is advisable to wear materials like fleece which will keep you warm, even when wet, and which remain light even if you get water on them.
