go on days with smaller swell size (smaller than 2 or 3 ft is usually good on magicseaweed), look for longer periods days (ideally 10+ seconds), look for calm wind (usually up to 2mph in the mornings, around 5,6 mph by 11pm and 10mph-ish by 3pm would not be a bad day).

Honest opinion, this weekend may not be GREAT weather. It might be OK. It looks windy out right now, BUT could change... who knows.
