For all locations watch out for heavy rain and/or strong/gusty winds. Make sure your crew understand clothing requirements. Bring some refreshment and something to eat.
If a coastal location, beware of wind direction (onshore can be dangerous as it may ‘break’), a big swell (> 0.5m) may remain for 2 days after a ‘blow’ and can capsize a skiff, especially when launching and recovering. The link below will give you all this information.
