Hello and welcome to the R.T.A forums.

It is impossible to make predictions this far ahead and as we know this time of year is unpredictable, you are open to the possibilities of rain, snow, ice, fog and clear,sunny days. The best you can do is to monitor the weather nearer the time by using such links as The weather channel or Weather underground.

As for the roads, they are well maintained and the Interstates are the main priority to keep open and are rarely subject to any major delays due to weather. The 101 is also a much used route and shouldn't cause to many, if any problems. However if the weather is kind and you have the time you may want to head for coastal route 1, it's a fantastic scenic drive.

If you need any other info don't hesitate to ask.

Have a safe trip.
