Miyajima Fire Festival in October and early autumn colour makes this a genuinely great month without April's price spike.

#1 for beach weather

April

Best match

Cherry blossom peak plus Golden Week builds a crowd double-whammy — the Peace Park rows are stunning but photographed around tripods.

#2 for beach weather

March

Best match

Cherry blossom builds through late March — Peace Park sakura rows are exceptional when they peak before Golden Week crowds arrive.

#3 for beach weather

November

Best match

Autumn foliage peak on Miyajima and Shukkeien — the maple canopy around the garden pond is genuinely special mid-month.

#4 for beach weather

May

Strong option

Golden Week (May 3–5) is the busiest few days of the year — book or avoid entirely; rest of May is fine.

#5 for beach weather

December

Strong option

Quiet and cold — the Peace Museum at Christmas week is sobering but uncrowded, and Miyajima's oyster season is at its peak.

#6 for beach weather

September

Strong option

Typhoon season peaks — check forecasts daily, but clear days between storms offer some of the year's best light on the torii.

#7 for beach weather

August

Strong option

Peace Memorial Ceremony on Aug 6 draws the world — the candlelit lantern release on the Motoyasu River that evening is unmissable.

#8 for beach weather

January

Worth considering

Cheapest month of the year — cold and grey, but the Peace Park is almost entirely yours and hotels are at bottom price.

#9 for beach weather

February

Worth considering

Still the off-season — plum blossoms at Shukkeien Garden arrive late Feb, an early sign of spring before the sakura rush.

#10 for beach weather

June

Strong option

Rainy season (tsuyu) dumps 210mm in the month — indoor museum time, but the Itsukushima shrine in light rain is actually atmospheric.

#11 for beach weather

July

Worth considering

Post-rainy season humidity and heat — the A-Bomb Dome at dawn before the 33C midday heat is still moving but sweaty.

#12 for beach weather
