The instrument that registered the speed was, ironically, destroyed by violent localised gusts soon afterwards. Shetland, which consists of more than 100 islands, with 15 of those inhabited, generally enjoys a pretty mild climate. Winter sees the strongest winds, sometimes reaching up to hurricane force (above 73mph or 117km/h), while it’s far calmer in spring and summer. And thankfully the landscape is pretty hilly, with sheltered valleys offering respite on the most blustery days.
