Northern Ireland’s 2026 Bathing-Water Ratings: Read the Period Behind the Grade

A beach can have an annual water-quality classification and still need a separate check before a visit. Northern Ireland’s October release is a useful example of why swimmers should read the time period behind a rating rather than treating an attractive grade as a live status light.

What the October results measure

DAERA published the 2026 classifications on October 8. Of 33 identified bathing waters, 25 were rated Excellent, four Good, three Sufficient and one Poor. The department explains that classifications use bacteriological results over four years. Rea’s Wood was the sole Poor site, for a second consecutive year; the announcement records advice against bathing throughout the 2026 season. These are Northern Ireland results, not a classification of all UK waters. Read DAERA’s dated announcement.

The department’s monitoring guide distinguishes sampling for faecal indicator bacteria from visual assessment for possible pollution incidents. Its dashboard provides site information and sampling results, but the guide explicitly says results are not real-time. See how Northern Ireland’s monitoring works and access the official dashboard.

Keep three questions separate

For trip planning, we recommend writing down three different questions. What does the annual classification say? What current advice applies at this named location? What access and operating information applies to the activity you have planned? A result answering the first question should not be silently used as an answer to the other two.

This distinction is especially useful when comparing destination guides. One article may quote an annual rating while another describes a temporary notice. They can concern the same beach and still describe different evidence. Check the dates and scope before deciding that one contradicts the other.

Make a more useful destination note

• Save the exact name. Avoid substituting a broad town or coast name for the identified bathing site.
• Save the evidence period. Record the year of a classification and the date of any individual sampling result.
• Save the current source. Bookmark the official site-information page rather than relying on a screenshot that cannot update.
• Read local instructions. Check the operator’s current advice and on-site notices. A historic classification cannot establish the conditions of your visit.

Find the site and the result behind it

Start with DAERA’s monitoring guide, which lists the 33 identified sites and the 2026 classification table. Use its direct dashboard link to locate the same named place through the map, search or filters. Look for the sampling date and the linked Bathing Water Profile, rather than reading the colour alone. The guide also links to out-of-season monitoring data, which is collected to inform future policy.

If two similarly named beaches appear in your research, resolve that difference before saving the result. Portrush Curran and Portrush Mill, for example, are separate entries in the department’s list. A town-level search is not enough to know which result you have found.

For an actual visit, read the authority and operator’s latest advice and the signs at the location. We checked the published classification and monitoring explanation, not the conditions at each site today. Keep those destination notes with your packing list; product questions about swimming equipment listed by TRIMIX can be checked separately here.
