https://www.inspectnext.com/I was recently laid off, so tried to merge a few of my hobbies and have made the site above to assist beekeepers in deciding the best times for inspections.
It allows you to choose your own Optimal/Viable inspection conditions (gear in top right, units Imperial or Metric too), as well as trying to tell you the best time slots for both Optimal, Viable and inadvisable condtions.
I hope this could be of some use to you, and if you have any criticisms or comments I would be keen to hear them.
