Spring periods are centred on the highest predicted high water in each lunar cycle; the shaded window varies with spring size (1–3 days either side). Size (small / moderate / large) and rank are relative to all springs in the peak's own calendar year, so dates outside 2026 show their year: a spring's rank isn't comparable across the year boundary.

Ranked against all springs peaking in 2026, highest first.
Ranked by height within the 1 Sep 2026–28 Feb 2027 window, the UK's storm-surge season, when large autumn/winter springs are most likely to coincide with Atlantic low-pressure systems and elevated coastal flood risk. Automatically moves on to next year's window once the current one has passed. This "season rank" is independent of the calendar-year rank shown on the other tab, since the season spans two calendar years, so dates here always show the year.
Tides: Liverpool (Gladstone Dock) tide predictions from the National Tidal & Sea Level Facility (NTSLF), National Oceanography Centre. A single well-correlated standard port is used as a national proxy, because the spring/neap rhythm and its annual peaks are driven by the lunar cycle and fall on essentially the same dates around the coast. At Liverpool high waters reach ~9–10m during large springs and ~7.5m at neaps; only the relative strength of each spring tide (size and rank) is shown, not absolute levels for other places.
The address of the Model Viewer and Model Multi now follows what is on screen: the layer, Areas, isobars, temperature values, split screen and the rest. Bookmark it, or save it as a shortcut, and it opens the same view at the latest run. For a quick link to one parameter, add ?param=rain (or temp, cloud, wind) to the address.
The Cloud layer now shows white cloud over a darker map, so it stands out clearly, and you can switch between Total, High, Mid and Low cloud to see which layer of the atmosphere the cloud is in. It works on every model on the Model Viewer and Model Multi.
Temperature on the Model Viewer is now drawn in 3 degree colour bands, and a new Anomaly layer shows how far each model's 2 m temperature is above or below the normal for that date and hour, against 1990 to 2019 (set to the Met Office's 1991 to 2020 averages over the UK), in blue to red bands. Turn on Show temperature values in the settings menu to print the numbers on the map. Tap Space to flip between temperature and anomaly, or hold it to peek. The Split screen switch on the bar shows temperature on the left and its anomaly on the right.
