* Good sturdy chair. A crappy chair will make you want to leave in the middle of something interesting. A large lounger is my chair of choice as I can set peripherals/laptop beside me without putting them on wet grass.

* Shaded spot under a tree.

* Extra router or Wi-Fi extender so you aren’t limited to right beside your house/cottage. Hotspot might work as well depending on where you are.

* Plastic bag to toss your computer in if it suddenly starts raining.

* Umbrella or towel covering. I like to build myself a cave of sorts to keep the light away from the screen. If you really want to invest, get an umbrella with a steel base and steel rods.

* Your phone so you can still do your meetings even if the extender is spotty.

When I get a chance to do this I am doing it lakeside in Northern Ontario at my grandparents place, so your mileage may vary.
