Narrative: On the flight from to ZZZ. We were on descent to 11;000 feet when ZZZ Center said they had a relay from company for a flight from ZZZ1 to ZZZ2. I asked Center to stand by while I try to get weather. I was able to check weather and determine that the weather looked good; briefed my crew; also briefed that once we got on the ground that I would do an updated weather check since conditions over the [area] were changing fast. Center cleared us to ZZZ1 they then handed us off to Approach; they cleared us to 6;000 feet then to 4;000 feet. I got the ZZZ1 airport in sight. Approach cleared us for the visual approach. I listened to the automated weather in ZZZ1 again and the winds had changed and this was confirmed when I checked in with ZZZ1 Tower. They were 140 degrees at 25kts gusting 37kts. The active runway was Runway 20. I advised Tower that was past our crosswind allowed. I cancelled IFR and requested to hold in visual conditions at 4;000 feet while I call Dispatch. I tried 3 times to call Dispatch on the VHF radio but didn't get a reply. We decided to abort ZZZ1 and head for ZZZ. I notified ZZZ1 Tower of our intentions. They told us to contact Approach. I contacted Approach and advised them of our intentions and climbed to 4;500 feet and reprogrammed the FMS and checked weather at ZZZ. I saw traffic on the TCAS at our 8 to 9 o'clock position and at that time; Dispatch contacted me on the VHF radio. They wanted to confirm that we were aborting. I confirmed that we were aborting and heading to ZZZ. At that time; the call from Dispatch stepped on radio transmissions from Approach concerning the traffic. I verified with the crew if I missed a radio call or not. No calls were missed. Approach gave me updated weather for ZZZ and asked if I intended to use Runway 26. I said I did plan to use Runway 26 if it didn't conflict with any traffic. Approach said it didn't and that to please stay on the current heading since there was a Citation to my south and maneuvering for Runway 30. I continued at 4;500 feet until I had the ZZZ airport in sight. FMS showed I was 14 miles from ZZZ and I had it insight. I told Approach I was maneuvering for runway 26 and asked to change to the local traffic frequency. Approach approved me through the Class D airspace and to switch frequency. I switched frequency and made the appropriate radio calls. I configured the airplane for landing. I started to notice that the winds were different than advertised but chalked it up to changing conditions. The winds were within limitations. I performed a normal flaps 30 landing. On roll out; I noticed things were not as expected. I realized I landed at ZZZ3. I got off the runway as soon as I could. I came to a stop after clearing the runway. Did the After Landing Checklist. Pulled up the chart for ZZZ3 on the FMS. Called Ground Control. They said to state intentions. I said if it was possible; I would like to continue to ZZZ. They asked what runway I would like. I requested Runway 30. They cleared me to taxi to Runway 30. I got the ATIS and reprogrammed to FMS. I briefed my crew. We decided I was still safe to fly us over to ZZZ. I switched to Tower frequency and told Tower I was ready to take off. They cleared me to take off runway 30 and did my Line Up Checklist. I then took off and headed straight to ZZZ. I switched to the local traffic frequency when advised by Tower. I got updated weather. Made the appropriate radio calls. I landed on Runway 26 in ZZZ. I taxied clear of the runway and did the After Landing Checklist. Taxied to the ramp and shut down the airplane did the Shutdown Checklist.  Human Performance Considerations: Night time with light to moderate turbulence. Changing destinations in a short period of time; multiple communications happening at once or in a close time frame [from] ATC; crew; and Company. I should have requested a IFR clearance back to ZZZ; instead of remaining VFR. I started the flight IFR and should've ended it IFR. When I was getting task saturated; I should have requested a hold until I had everything sorted and not task saturated. I could've then accomplished the RNAV approach and circled to runway 1 or 26 at ZZZ. I could've asked my crew to handle the communication with company and turn that audio off. Once the problem was discovered and I landed at ZZZ3; I should have requested to taxi to the FBO instead of requesting to continue to ZZZ.
