The crucial thing to understand is how the three weather states control everything in the environment. During fallow periods monsters get way more aggressive since food's scarce, while plenty makes herbivores graze openly which creates perfect ambush opportunities. You'll notice apex predators like rey dau only show up during inclemency, and their spawn points are marked by intense lightning strikes in places like windward plains.

Weather shifts happen every 15-20 minutes naturally, but if you're farming specific monsters you can force changes by resting at camp for 300 guild points. Something interesting - visibility drops 30-50% during extreme weather which affects both your tracking and the monsters' detection ranges. Keeping an eye on the environment details panel in the bottom-left is crucial since it shows exactly what phase you're in.

The really technical part is how monsters adapt their pathing to avoid environmental hazards. During sandstorms they'll seek shelter which changes their usual routes, while thunderstorms make them more cautious around open areas. Resource nodes also cycle availability based on weather - about 87% of gathering points shift with the conditions. Maybe worth noting that during inclemency phases, specific areas become near impossible to traverse without the right equipment and buffs active especially in spots like oilwell basin where you'll need cool drinks ready.
