Swansea high water this coming Sunday is 0939hrs, low 1545hrs; 9.7m and 0.9m respectively. Near as dammit springs, so Tawe Lock (essentially the Marina's front door) will close for three hours from 1415hrs, and won't therefore open again until just after dark.
Forecast is currently F4, just a shade south of westerly. Not sure what the rest of the weather is doing, though note it's just tried to snow outside so doubt it's going to be exactly balmy. You never can tell however.
If we can arrange to get Calstar back in the water this week, it might be we'll finally get the chance to take her out to play Sunday morning.
