<p>Average</a> Weather for Princeton, NJ - Temperature and Precipitation</p>
<p>We will be at school from September through the middle of May. Would it be wise to pack mostly warm clothes?</p>
<p>no, it gets pretty cold in the winter</p>
<p>^I think that’s what he means by warm clothes.</p>
<p>It gets chilly in November, extremely cold in Dec-March, and it’s chilly till mid April. Basically, it’s cold from a month after you get to Princeton to the month before you leave.</p>
<p>Actually, this year we had some bizarrely warm weather in early April (up to 90 as far as I recall). I remember it was quite warm on April 2 (the day after decisions) when I walked around campus for several hours with a silly smile on my face =) I would say it averages mid 50’s in March, mid 60’s in April, and low 70’s in May. But NJ weather is really inconsistent, so be ready for all eventualities!</p>
