Rothesay enjoys a maritime climate with mild winters and modest sunshine; the most settled weather runs from May to early September. For today’s conditions, check the live forecast above, then plan your layers and a waterproof jacket.
When is the best time to visit Rothesay?
Late spring through early autumn offers the driest, sunniest spells. June and July see average highs around 17 °C and the longest daylight hours. School holidays bring more visitors, so book ahead if travelling in August. If you prefer quieter streets, May and September are excellent value – the weather remains fair but crowds thin.
What should I pack?
Even in summer a light fleece and a windproof raincoat are essential. In winter add a warm coat, hat and gloves. Sturdy, waterproof footwear is wise year-round, as Rothesay’s hilly streets can stay damp after showers.
Does it rain a lot in Rothesay?
Rain falls on about 160 days a year, but showers tend to be showery rather than continuous. The driest months are May and June, making them a good choice for a trip.
Is Rothesay very windy?
The island can be breezy, especially from October to March. Sheltered bays and the promenade offer calmer spots, but a windproof layer is always advisable.
Can I swim in the sea at Rothesay?
Yes, but water temperatures peak at around 13–14 °C in August. A wetsuit is recommended for extended swims; the bay is safe with gentle slopes.
