Sorry I am late to the thread, but I just joined the forum.
I have only been after hogs since 2008 and my place is fairly small, but bordered by other rural property, and I now hunt on multiple properties. On my place which is all of 46 acres, I run anywhere from 7-8 game cameras at any one time. Even with that many, I don't always know when the hogs have been to my place and so they are actually there more often than I realize from the cams based on the damage that I see occurring. I have kept written accounts of every one of my successful hunts and have correlated them with everything from weather to season to moon phases. Here is what I have learned over these last few years.
Pretty much anything that anybody has told me that will work for knowing when hogs will be around or baiting hogs to be in sooner, more regularly, or staying longer is all just wishful thinking and happy correlations. I mean no offense to anybody, but I have tried a myriad of tactics and used other people's scheduling as well as my own and nothing seems to actually work. I blame the fact that my hogs in my area of north Texas are not starving to death and depending on the feeder to make it through the day or night in order to survive. The hogs here are healthy, comfortable, and are free to make numerous consumer decisions about what they want to do at any given time.
I looked into wind speed as an issue and believed for about 3 years that wind was a factor. It wasn't. I just didn't shoot many hogs during the first 3 years and as it turned out, most were not during particularly windy nights. I have not shot many hogs during windy and VERY windy nights. This sort of result is what leads me to believe that a lot of people's claimed correlations for hunting success because of some sort of noted pattern is likely a sampling issue more so than a bona fide pattern.
Storms - supposedly the hogs move just ahead of the storm or just after storms. I am sure they do. I have shot them then. I have also shot them when there were no storms. I am sure they move just about any time. Just because a storm is or is not coming or has or has not passed does not change the fact that the hogs want to eat each and every day. Be it in the wind or storms, hogs may alter their behavior to be places during those conditions that they prefer, such as in the bottoms, in the woods, in clearings, etc., but they are going to be somewhere and doing their thing. The question is whether or not you are where the hogs are, not whether or not they are apt to be moving. When they aren't bedded down, they are generally moving.
Solunar schedules and phone apps - neat stuff. I know folks that swear by them as noted above. The funny thing is that there are a variety of solunar tables out there for which you can identify virtually any day or time of day that is predicted to be good depending on which version you choose to examine. Depending on the solunar tables I have used, I have shot a lot of hogs during periods where I should expect a very low chance of having an encounter.
I have shot no moon to full moon and in looking at the moon pattern, I have more shot hogs during moon phases that are longer, less for those that are shorter. Go figure. That is pretty much random chance patterning. The hogs eat regardless of what the moon is doing.
Temperature changes - same as storms. Hogs are going to be moving regardless of the temps. The question is then one of when they will be moving and whether or not you will be there at the time they choose to move. I have found no correlation that just because the temperatures drop that all of a sudden hogs start showing up on camera at my place, be that crossing through the fences, in the food plot, or at the feeders.
Scheduling - My wife suggested that I give hogs inexpensive digital watches for Christmas last year to help reduce my frustration at the hogs not showing up on time or as expected. Apparently, hogs do not wear watches or use day planners. I have seen hogs come at the same time for several days in a row, every other day, every third day, and then seen them change their time or stop coming all together for no apparent reason. On several occasions, I have shown up several hours early before when the hogs might return based on the documented schedules shown from the game cameras only to find that they hogs were already there when I arrived or arrived within minutes of my arrival. Those have been some of my shortest hunts.
For a while I had exceptionally good luck (for me) hunting based on when my mother-in-law would show up to stay for a night or two, often with no more advanced warning than a couple of hours. She would show up and so I would go hunt about an hour after she arrived regardless of whether or not there was any indication on the property or from game cameras that I had hogs. While I know not of the witchery involved, my MIL could come, I would go hunt, and shoot a hog when none had been there in weeks. I was batting about .250 based on her random visits. Then she moved to town and that scheme fell apart.
Based on MY experience, the only thing consistent about hogs is that they are inconsistent. They continually do things that are not expected.
I will say this about general behavior, however. A sounder of sows, shoats, and piglets, maybe with a boar or two tagging along seems to have a herd mentality in many cases...which means the IQ level of the group is like that of a MOB and reduced to the lowest common denominator. They often make considerable noise, are less afraid, and more apt to return to a location where one of their members have been shot than what you would get when hunting a lone boar or small bachelor group (usually no more than 2-4 individuals). Single boars and bachelor groups tend to be quieter, more skittish, and if you shoot one from the group, the rest of the group is not as likely to return that evening. I have never shot a hog during a significant downpour and I have only had a very limited number of pictures of hogs during rainstorms on my game cameras, though they don't seem to have a problem being out during light rain or heavy fog. When it is really hot, they are less apt to move during the day, but as the summer continues and they get used to the heat, I will probably end up with a couple of hogs making daylight appearances sometime in August or September, probably not the middle of the day, but then again, I virtually never have hogs in the middle of the day anyway. My hogs tend to be crepuscular and/or nocturnal.
Find what you think works for you and maybe it works for you, for a while, in your general area, for your circumstance, with your particular hogs. Hopefully, you will find something that works well for an expended period of time, but don't count on it. However, what works well for you in your situation may not work for me in my situation in any sort of replicable manner and vice versa. That is the nature of hogs as I have discovered and continue to discover.
