Regardless of where you are located, summer is the best time to ship from anywhere to anywhere as weather and road conditions are at its best for the most if not all of the country. Although some locations are still off route and may cost more, planning routes to and from these locations is easier. Driver availability and flexibility is better and planning transportation is easier not only for drivers but for customer as well. Families looking to relocate have it easier as kids are out of school, students coming back from college sessions and so forth. One of the disadvantages for shipping during summer are elevated gas prices, although it is not always the case, summer is the time when gas prices sky rocket and readjust at higher points.
Fall and spring share similar conditions as they are both related to the peak of summer ending to winter and winter ending to summer. These seasons are also great for transportation, especially when heavy snow falls are off the radar. Fall and spring are season that mark the start and end of a very important time mainly for east and west coast routes as hundreds of snowbirds are looking to relocate for the seasons. Fall initiates the snowbirds move to the south and spring initiates their trip back north. East and west coast are at their busiest at this time trying to relocate customers as soon as possible before snow starts to fall.
Winter season, although is also high in demand for transportation, is more hectic and is more probable for delays. Some routes are shut down as they are not very safe, and moving all over the country is harder. Northern states are the most affected as snow fall is the heaviest, even drivers who usually have their routes through the north look to relocate for winter in the south as demand is higher. Fortunately for southern states, weather conditions are great even during winter and demand is not affected. Customers move back and forth from coast to coast with no hassle or delays.
