What to expect
- Temperature feel - Pleasant warmth with an even, steady feel across the day. Most days feel pretty true to the forecast.
- Showers & dry spells - Showery bursts. You’ll get wet windows, then dry windows. You’ll want a proper rain setup rather than a ‘just in case’.
- Midday sun - Strong sun. Cloud cover doesn't always mean low UV, so still protect your skin. This is a 'don't forget the hat' month.
- Exposure - Refreshing breezes, and expect sharp gusts that can change plans in exposed areas. It’s the kind of wind you plan around for viewpoints and coastal walks.
