Visiting Saint John's in May
May weather in Saint John's
May feels warm and sticky, with highs around 28°C and little drop after sunset. Rain falls on many days, though it doesn't mean every day is a washout. Showers can interrupt a walk around the city, so keep indoor stops like the Museum of Antigua and Barbuda in mind.
You'll still have time for St John's Cathedral, the market and a beach trip. But long, exposed walks can feel muggy, and cloud and showers may spoil a clear view from Shirley Heights. April is drier; June is a little warmer and wetter.
Events and crowds
Labour Day is marked in Antigua and Barbuda in May. It's a public holiday, so some services and businesses may close. There isn't a major island-wide festival to draw the crowds that arrive for Antigua Carnival later in summer.
If you hate crowds, May can suit you: it's quieter than the January-to-April high season. Demand eases, too, and stays are often less costly than in peak months, though prices vary. The trade-off is more frequent rain and a less dependable beach day.
Tips for Saint John's in May
Travelling with kids? A shower can make the beach less appealing, but you can switch to a short city visit without losing the day. Redcliffe Quay's cafés and shops are close to the waterfront, while the Antigua and Barbuda Museum offers a rainy-day stop nearby.
A practical tip: check the opening hours of St John's Market before you go. It's best known for its produce and local food, but the stalls are liveliest on market mornings, not on the Labour Day holiday. May's humid afternoons make a shaded café stop around Redcliffe Quay a welcome pause.
