Water crosses the sands faster than people expect on a big tide, and the causeway can submerge entirely on the rare island days. Check the live tide before you plan a crossing.

The first two days are the most reliable. Yr.no publishes hourly resolution for roughly the first three days, then six-hour blocks out to nine days, and confidence falls the further out you read. Treat the last few days as a trend, not a plan. How often does it update? We fetch a fresh forecast from Yr.no every six hours and only rewrite our copy when the numbers actually change. The timestamp at the top of the page tells you when the current forecast was pulled. What does the fog figure mean? It is the share of the area the model expects to be fogged in, from 0 to 100 percent. Anything above zero on a day you plan to walk on the sand is worth taking seriously: the bay fogs quickly and landmarks disappear. Is the wind speed an average or a gust? It is the sustained wind speed, not the gust. Gusts on an exposed causeway routinely run well above it, so treat the number as the floor rather than the ceiling. Why are some cells empty? Not every field is published for every hour. The final timestep carries no precipitation total or symbol, and the six-hour blocks omit some instant readings. Empty means not published, not zero. These are model predictions, not observations. Wind and pressure can push real conditions either side of the published figure.
