Night fishing in the summer is my preferred time to be on the water. I night fished for year growing up in ponds that maybe I wouldn't fish during the day, but that's another story and many years in the past. Now, I'll take the kayak and either show up an hour before sunset or more likely I'll be launching 2-3 hours before sunrise. First a first timer, a couple things:
1- start with a body of water that you already know. Night time isn't the time to be exploring a new lake. I'm talking about a lake that you can just go fish without thinking, without looking at a fish finder, and one that you already know which rocks, logs, and spots you're going to cast at before you hit the water.
2- going a couple hours before sunset will help. You can get on the water, get situated, get your casting rhythm and distance sorted before it gets dark. It will let your eyes acclimate to the lowered light gradually.
3- put a red cap or plastic over your light. From #2, your eyes take a half hour to fully dilate to true dark conditions. The tiniest bit of white light sets them back. Red light helps a ton to keep your night vision. I only use a light to tie knots and instead navigate by starlight/moonlight. I have a light with me in case of emergency, but I don't use it. I also turn off the navigation lights on the boat (I'm always the only one on the water).
4- long sleeves, pants, and a hat are a must. Bugs are always bad and DEET can only do so much. Also, any lures you snag and pull loose coom back faster than you think. At least if you have skin covered you're not getting a hook in the arm.
I love night fishing. Throwing frogs on grass mats at night is a special thing if they are eating them. The sound of a bass sucking down a frog in the middle of the night will shoot your heart rate through the roof. Big single colorado spinnerbaits with the thump will teach you all about feeling for a bite or a blade of grass when all you can do in pay attention to every whirl of the blade.
