The right forecast age in Track Designer Settings

Postby Asmith » Sat Feb 07, 2015 11:18 am

Hi, I am trying to prepare for the VORG start tomorrow. It starts at 0700 my local time (Amsterdam, 1 hour ahead of UTC). Its noon (1200) the day before the race. Thus the start is in 19 hours. If use ' a given date/time' option, set 0700 in the ' From date/time ' field, it gives a forecast ate of 1d 01h (25 hours), which is not correct. I see this also when I generate a route, it give a wind time 25 hours in the future where I am starting from, and not 19 hours. The only way I can get the right wind prediction time at my start location (1900) is to subtract 6 hours from the actual start time (which would then be 01:00 on 8 Feb.

I would like to be sure that the routing planning I am doing reflects the correct time and predicted best route. Can someone explain what I might be doing wrong?

Thanks.
Asmith

Sorry your post was not approved in time for the start... :mrgreen:

For that (planning before the start) you should set
time to Start Time less current wind forecast Timestamp
+ one hour. This hour is because regatta winds right now
are shifting at 13h age. On daylight saving time
that changes, I suppose (not sure).
