Hour by hour Met Office forecast for Royal Welsh Show 2026

The Met Office is forecasting a largely fine, warm spell for this year’s Royal Welsh Show, with dry conditions and sunshine on all four days at Llanelwedd, which hosts the annual Welsh farming jamboree.

Temperatures are expected to climb into the low‑to‑mid 20s Celsius each afternoon, with cooler mornings and evenings in the low teens, according to Met Office data.

Light winds, generally under 10mph, should keep it feeling comfortable around the showground, although it will still be hot in full sun.

Rain chances remain very low, at or below 10 per cent throughout the daytime periods, so only brief, isolated showers are possible.

Organisers say the settled outlook will be a boost for Europe’s biggest agricultural show, which runs from Monday 20 to Thursday 23 July.
