One thing is for certain: they're trying to prepare for the worst.
As I arrived at the rowing course for the first time at 5:30am yesterday, it was clear that every possibility had been considered: the course was lit up from start to finish by spots placed every 15 meters or so.
Not that they would need them at this point. As far as the venue, and especially the water, goes, so far so good. We've seen some wind, and a little chop, but nothing that you would even rig up for. And the wind isn't the steady tailwind that haunts the nightmares of junior rowers; we've seen headwinds, cross-heads, and, sure, the crosstail that makes the Meltima.
The worst may be ahead of us, however; 25 knot winds are predicted for early next week. All the measurements we've seen are in meters per second; here's an easy conversion:
1 meter/second = approx. 1.9 knots. So, if you take the meters per second, double it, and call it knots, you're pretty close. Thus, the 14 m/s wind predicted for Tuesday is a 27 knot wind; that's pretty brisk.
For a look at the venue in the minutes either side of dawn, have a look at the gallery of photos I took early Thursday morning; it's a nice spot.
