We compare the 7-day forecast to the last 5 years of marine data for the same week at Portrush. The delta tells you whether conditions are shaping up better, worse, or about the same as a typical early July.
We score each day of the 7-day forecast using the same algorithm as the leaderboard, and highlight the highest scorer.
Open-Meteo's Marine API (swell height, period, water temperature) and Weather API (wind and conditions).
Honestly, no. Every break has tide windows, swell directions and reef contours that a global model cannot see. Treat the score as a starting point, then check a local cam.
The best week for surf at Portrush is the week of 23 November (score 3/5) with low crowds.
Small waves but still worth a paddle for keen surfers. Full onshore mess. Not worth the paddle unless you are desperate. Conditions improving through the afternoon.
Heads up: jellyfish: high.

The air here is 66% cleaner than the average comparison city right now.
Noticeably cleaner air than a typical city. Good conditions for prolonged outdoor activity.
Not a pollutant. Ozone is naturally higher at altitude and near the coast, and lower in cities where traffic exhaust breaks it down. High readings here typically indicate clean air. Can cause short-term airway irritation during intense exercise but is not linked to the long-term health risks of particulate pollution.
Additive health score: each pollutant contributes points relative to its WHO 2021 guideline and long-term health impact (PM2.5 9, NO₂ 5, O₃ 3, PM10 2, SO₂ 1 at WHO limits). Data via Open-Meteo. City markers show live readings. Red line marks the WHO guideline. Updated 03:00

Local knowledge and community tips for Portrush
Portrush sits on the north coast of Northern Ireland, offering highly consistent beach breaks across East Strand and West Strand. The beaches face north and pick up Atlantic groundswell that wraps around the headland. East Strand is the more popular, a wide sweep of sand with multiple peaks and a reef section at the eastern end. West Strand is smaller and more sheltered. The Giant's Causeway is just down the road.
Picks up north-westerly Atlantic groundswell year-round. Works on all tides with mid-tide generally best for shape. A southerly offshore wind creates clean conditions. Consistent from September through May with the biggest swells in winter. The 3-6ft range is most user-friendly. Portrush rarely goes flat in winter.
East Strand has multiple peaks across the wide beach. The eastern reef section produces more defined waves but is for more experienced surfers. The sandy middle section is more forgiving. West Strand is gentler and works well for beginners. Pick your section based on your ability and the day's conditions.
Rip currents on bigger days, particularly near the reef section. Cold water (5-12 degrees year-round). The reef at the eastern end of East Strand is shallow and sharp. West Strand has rocks at either end. Strong currents can develop on a dropping tide. Lifeguards patrol in summer only.
Free parking at both beaches with direct access to the sand. East Strand has a large car park behind the dunes. West Strand parking is along the seafront. Full town facilities including surf shops, cafes, and changing rooms. Extremely accessible.
The main Northern Irish surf community is based here. Good days at East Strand can see 20-30 people in the water. West Strand is quieter. The community is welcoming and the lineups are generally friendly. Weekends are busiest. Visiting surfers are common given the town's reputation.
Portrush is the hub of Northern Irish surfing and for good reason: it is consistent, accessible, and varied. The reef at the east end of East Strand is the premium wave but needs a bigger swell and more experience. If Portrush is too small, Bundoran (an hour west over the border) handles more swell. The Harbour Bar is the traditional surfer pub. Do not miss the Giant's Causeway on a flat day.

View Best Time to Go →Combining historical conditions with school holiday crowd pressure to find the sweet spot.
The timing score combines two signals: historical conditions quality (how good the skiing or surfing typically is in a given week, based on 5 years of weather data) and crowd pressure (how many of this destination's feeder markets have school holidays that week).
Crowd pressure is weighted by each feeder country's share of visitors. If 40% of a resort's visitors come from France and France is on holiday, that contributes 0.40 to the crowd pressure score. Crowds can reduce the timing score by up to 35%, ensuring conditions still matter most.
Scores: 5 = great conditions with low crowds (the sweet spot). 4 = great conditions with moderate crowds, or good conditions with low crowds. 3 = average. 2 = below average conditions or very crowded. 1 = poor conditions or peak holiday chaos.
