Accuweather.com lists the average high for the first week of April as 81 or 82 degrees, with an average low near 60.
Records highs for the first week of April are in the low 90s. Record lows are near 40. So I'd just check the long range forecasts near the end of March to see what it will be like this year. As you can see, there is a pretty wide range.
We'll also be there the first week of April!! We're packing lots of shorts, but a few warmer pieces too...just in case. We are SOOOOOO done with winter!
Look for our lime green...we'll be looking for yours!
