Is there a day of the week that is worse for catching trout?

Updated: 3 days ago

Let me throw you a scenario. It's a sunny summer weekend and you want to go fish a popular stretch of river. Then you think, "Wait, won't everyone else be doing the same thing? Instead, what if I went the Friday before, or the Monday after? Fishing would probably be better, right?"

But, is that really true?

Maybe I'm the only one who would assume so, but I have repeatedly planned weekend fishing trips around what I expect other anglers to be doing. The more popular a stretch of water is, the less likely you'll see me there on a Saturday. But the same stretch of primo river on a Wednesday might have me drooling with excitement.

So, is there any truth to avoiding the weekends to catch more fish? As with anything in fly fishing, there is no absolute truth without a healthy dose of exceptions. However, we can start to call upon our past experiences to untangle this question. As you may or may not know, I'm a big proponent of keeping a fishing log to track information that summarizes each outing. Think of a fishing log as a farmer's almanac, something you can look back on to help predict and prepare for future trips. A fishing log can also help us reflect on past outings.

I can call on my fishing logs to figure out which days of the week caught me the most fish, and see if there is a dip in catch rate during the weekend. Of course, this information is only true for me, but any data is better than none! Let's break down this graph (below) and figure out what we can learn from my almanac.

In the above figure, you'll notice each day of the week has an average catch. This is based on an average of all the fish I've caught on that day of the week. Go ahead and judge me now and get it out of the way! Fair warning, I did exclude the outlier days, including days with 0 fish and days with over 20 fish. Now consider the error bars associated with each day of the week. Think of this as a range, so for any Sunday I'm fishing, I have historically caught anywhere between 3 and 15 fish. Look at how wide the error bars are for every d
