Look into groupsummary. You'll probably want something like this. I'm assuming your data is in a table.
groupsummary(tblName,Date.time,'hour','mean',spread)
I wouldn't call this a weighted average, though. You'll need to provide more details about how you want to time-weight the average.

Or put the data in a timetable and use retime(tt,'hourly','mean'). If you need weights, you can write your own aggregation function for hourly aggregation.
