SpringMarch - May
Punting restarts, the Botanic Garden wakes up, and on 1 May the whole city gets up before dawn for May Morning under Magdalen Tower.
Spring is when Oxford's rivers come back into play. Magdalen Bridge Boathouse opens its punting season in February but it is April and May before an hour on the Cherwell is reliably pleasant, and the Botanic Garden's walled borders start moving well before the trees on the High Street do. The city's one unmissable spring date is May Morning: at 6am on 1 May, Magdalen College Choir sings from the top of the Great Tower to a packed Magdalen Bridge below, a tradition the city council closes roads for, and the pubs open early afterwards. Trinity term fills the colleges from late April, so check opening pages before planning a college visit; exam season tightens access as the term goes on. Bring layers, because the river meadows hold a cold edge well into May.
SummerJune - August
Peak season. Punt early or late, walk Port Meadow in the evening, and book the riverside pubs rather than hoping.
June to September is peak Oxford, and the centre genuinely fills: coach parties around Radcliffe Square by mid-morning, queues at Christ Church, and every punt at Magdalen Bridge out on a warm Saturday. The moves that work are timing moves. Punt before noon or after five. Do the big library and college visits early, then spend the afternoon where the crowds are not: the Botanic Garden, the Thames Path across Port Meadow, or a river cruise from Folly Bridge. Swimmers and picnickers colonise Port Meadow on hot evenings, and the walk out to The Perch at Binsey or The Trout at Wolvercote is the classic summer evening plan, with a booking at the end of it rather than a wait. The colleges are out of term from late June, which usually means longer visiting hours, but ceremonies and conferences still close them at short notice, so check the day before.
AutumnSeptember - November
St Giles' Fair takes over the city's grandest street in early September, then Michaelmas term brings the students back in October.
Autumn opens with St Giles' Fair, two days in early September when funfair rides fill the length of St Giles from the war memorial to the city centre, a tradition dating to a 1625 parish festival and still one of the biggest street fairs in Europe. Michaelmas term starts in October and the city changes register: gowns at matriculation, bikes everywhere, and the colleges busier and sometimes less open to visitors, so check opening pages before queueing. This is the best season for the indoor Oxford, the Ashmolean, the Divinity School and the two university museums, all free or cheap, and for the Covered Market as the food stalls turn toward winter. The light on the stone in late October, when the tourists have thinned and the sun stays low, is the version of Oxford photographers wait for.
WinterDecember - February
The Christmas Market runs on Broad Street from late November, the museums are free and quiet, and the old pubs earn their keep.
Winter Oxford is the indoor city, and it is a strong one. The Christmas Market sets up on pedestrianised Broad Street from late November through December, with Blackwell's and the Sheldonian as its backdrop. The Ashmolean, the Museum of Natural History and the Pitt Rivers are all free, warm and genuinely world class, which makes a wet January day here easier to fill than in almost any city this size. The medieval pubs do their best work now: the Turf Tavern's braziers in the yard, the Bear's tiny rooms, real fires out at The Perch and The Trout if you fancy a cold walk with a warm end. Port Meadow floods in most winters and the flooded meadow full of wildfowl is a sight in itself, but keep to the Thames Path with proper footwear and expect sections to be impassable after heavy rain. Hilary term runs from mid January, so weekday college access stays limited.
