Warm Weather Propagation at 915MHz
Can heat and humidity affect propagation? Apparently, yes.
Courtesy of Grok, the heat spreads out the molecules in the air and changes the reflectivity of the atmosphere. This might result in your rf signal getting more scattered than at lower temperatures.
Higher humidity means more water molecules in the air to absorb your signal, attenuating it further.
I happened to be up at 5:30 am this morning, and tried to traceroute to some adjacent nodes that I have been able to reach up until recently. I was able to reach 5 out of 6. But by noon, only 1 of the 6 was still reachable. Try it yourself and post your results here.
