Truthfully it can be a little hit and miss. Most marina's in the Pacific Northwest are well equipped. Cellphone data tends to be pretty useful for coastal cruising with Canada - but watch out for roaming rates in international waters! On blue water sailings you can receive weather forecasts through airmail (provided by SailMail). Airmail uses HAM radio technology to receive weather data, i've seen it used but have yet to understand the nuts and bolts of it myself. I will say the times where I do not have an internet connection are a time of solace and simplicity.
