While exact weather conditions typically can’t be predicted more than a week in advance, here’s a seasonal outlook to help you prepare for what winter will bring.
Reminder: The first day of winter is on Saturday, Dec. 21.

That December drop
OK, OK, we’ll grab our coat. This month’s temps range from an average low of 43° to an average high of 56.5°. It’s one of SJ’s rainiest times of the year, with an average of 7.6 rainfall days.
January
Temperatures will rise a tad from December. Historically, the average low + high temps are between 43.3° and 58.1°, and with predicted higher temps, you may be still able to enjoy outdoor activities.
February
