All months ranked — Beach weather
Best match
Miyajima Fire Festival in October and early autumn colour makes this a genuinely great month without April's price spike.
#1 for beach weather
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
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
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
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
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
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
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
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
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
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
Worth considering
Post-rainy season humidity and heat — the A-Bomb Dome at dawn before the 33C midday heat is still moving but sweaty.
