    “When do coastal floods happen? ⏱️🌊
    A new study [link above] shows that, in many tide-dominated coastal regions, flooding tends to occur at specific and recurring times of day. Rather than being completely random, flood events often cluster around predictable hours driven by local tidal patterns.
    By analysing coastal flood observations from the UK and the US, [the authors] show[ed] that the timing of flood events can be highly structured, with some locations experiencing floods disproportionately during certain parts of the day.
    This adds a temporal dimension to coastal flood risk. We often focus on how frequently floods occur, how severe they are, and where they happen. This study highlights that when they occur may also matter, particularly as rising sea levels increase the frequency of coastal flooding.
    The findings provide a useful perspective for coastal adaptation, risk communication, and emergency planning…”

    “Flooding is typically perceived as a sudden and unpredictable hazard. Here, [they] show that recurrent flooding can occur at highly predictable times in tidally dominated coastal systems. This predictability stems from phase-locking of tidal constituents and constituent pairs with the solar day, causing peak tides to recur at consistent local times set by regional tidal propagation. Using tide-gauge records from the United States and the United Kingdom, [they] quantif[ied] the intraday timing of coastal flood events and show strong clustering at specific hours, particularly where semidiurnal or mixed tides dominate. For example, floods in Boston cluster around noon and midnight, whereas in southern California they occur in the morning. Sites with stronger non-tidal variability show weaker clustering. This temporal predictability extends beyond nuisance flooding to larger consequential events involving inundation, road closures and infrastructural damage, highlighting opportunities for anticipatory risk communication, emergency planning and time-sensitive coastal adaptation…”

  2. The Tide Coming In at Youghal

    A line of old groyne posts runs out into the sea at Youghal, the nearest ones capped in green weed, the far ones worn down to stubs. I used a long exposure to smooth the incoming water into streaks across the brown sand. The evening was flat and quiet, the sky a soft blu...

  3. The Tide Coming In at Youghal

    A line of old groyne posts runs out into the sea at Youghal, the nearest ones capped in green weed, the far ones worn down to stubs. I used a long exposure to smooth the incoming water into streaks across the brown sand. The evening was flat and quiet, the sky a soft blue turning to yellow as the sun set. The posts have been here long enough that the sea has taken most of them.

  6. Tides are important for a bunch of oceanographic and geodetic stuff, also for just meretime operation (and coastal living) in general. So we spend a lot of time and resources monitoring it. With so much data, we can see some patterns.

  7. Youghal’s Wooden Sentinels

    Groynes in the sand as the water rushes away to do battle with another wave coming in. The ever-present push and pull of the tide, defeated for some time at least by these wooden posts....

  9. Nature/G-d is cruel, even to herbivores. For example, I've seen sea turtles, who feed on shoreline plants at dawn and dusk, be unable to reach their food, due to the changing timing of the tides. Some days, I guess they just go hungry.
