Day 1: 2026-04-18

CATEGORY 2

WHAT
Saturday will see routine conditions with no significant flooding risk. Tides are expected to be the primary driver, but overall levels remain below flood thresholds.

WHEN
Peak high tides occur around mid-morning (about 04:24) and late afternoon (about 18:12).

IMPACTS
• No impact anticipated.

REASONING
Tide contributed the most (+0.332) while pressure had a minor effect (+0.019). One of the closest analogs was 2025-01-06 (Cat 3), which was slightly higher in category.


Day 2: 2026-04-19

CATEGORY 3

WHAT
Sunday is close to flood conditions, so keep an eye on shoreline areas. Elevated tides and somewhat lower pressure raise the risk, but only minor impacts are likely.

WHEN
Highest water levels occur early morning (about 05:00) and early evening (about 19:06).

IMPACTS
• Minor inundation possible at the immediate shoreline.

REASONING
Tide (+0.367) and pressure (+0.061) combined to produce this Category 3 rating. This is similar to the 2023-12-27 Cat 3 event.


Day 3: 2026-04-20

CATEGORY 3

WHAT
Conditions Monday remain on the edge of flood thresholds, again driven by moderate tides and modestly low pressure. While not severe, these factors bear monitoring near the waterfront.

WHEN
Peak high tides occur around early morning (about 05:36) and again in the evening (about 20:06).

IMPACTS
• Minor inundation possible at the immediate shoreline.

REASONING
Tide was again the main contributor (+0.367), with a small boost from pressure (+0.056). Another day resembling 2023-12-27 (Cat 3).


CATEGORY KEY
• 1–2: No flooding risk (“no risk,” “routine”)
• 3: Worth monitoring (“close to flood conditions”)
• 4: Flooding likely, moderate property impact possible
• 5: Flooding likely with significant property damage
• 6–7: Extreme flooding risk
