While trail conditions will remain wet, this window looks promising for sunrise visibility at the summit. Climbers should bring full waterproof layers, warm clothing, gloves, reliable lighting, and traction for slippery sections. With adequate preparation, this is a good opportunity for a safe overnight climb and scenic sunrise.

Daily forecast for July 22

Climbers setting out from Mt. Fuji’s 5th station on July 22 and planning to summit for sunrise on July 23 can expect mild but damp conditions with a promising outlook for sunrise visibility. Afternoon rain is expected on July 22, especially above 3,000 m, with summit temperatures around 7–8 °C and light winds (5–10 km/h) continuing overnight. At the 7th station (~3,000 m), conditions will be similarly mild but humid, with wet trail surfaces. Cloud models show gradual clearing through the early morning, with a good chance of reduced cloud cover and improved visibility by sunrise. Japanese meteorological commentary notes lingering low-level moisture into the night but forecasts clearer conditions around dawn. While the route may be slick and cold, conditions are relatively stable. Climbers should bring waterproof layers, warm insulation, gloves, lighting, and waterproof hiking boots.

Daily forecast for July 21

Climbers departing from Mt. Fuji’s 5th station on July 21 and aiming to summit for sunrise on July 22 can expect relatively calm and mild conditions. Light rain (~4 mm) may fall in the morning, but summit temperatures will hold around 6-8 °C with light winds easing overnight. At the 8th station (~3,400 m), trails will be damp but manageable, with mild temperatures near 8 °C. Cloud cover is expected to thin gradually through the night, becoming partly clear by dawn and offering a strong chance of sunrise visibility from the summit. Japanese meteorological commentary notes residual low clouds with visibility expected to improve around sunrise as moisture decreases. While trail surfaces may still be slick, conditions overall are stable and favorable. Climbers should carry a waterproof shell (top and bottom) with mid layer insulation, gloves, headlamp, and proper water proof hiking boots. For those properly equipped, this appears to be one of the best summit and sunrise windows in recent days.

Daily forecast for July 20

Climbers departing from Mt. Fuji’s 5th station on July 20 aiming for a sunrise summit on July 21 can expect a favorable weather window. At the summit (3,776 m), light rain (~4 mm) is expected mainly during the morning, with mild temperatures around 7–8 °C and light winds easing overnight. At the 8th station (3,400 m), conditions will remain mild (8 °C) with damp trails and calm air, while cloud cover thins through the early morning, leading to partly clear skies at sunrise—offering a strong chance of good visibility. Japanese meteorological commentary notes lingering low clouds but forecasts clarity emerging by dawn as moisture decreases and winds shift. Though trails may still be slippery and cold, climbers should be equipped with a waterproof shell, warm layers, gloves, headlamp, and traction gear.

Daily forecast for July 19

Climbers departing the 5th station on July 19 to summit for sunrise on July 20 can expect a favorable weather window. Summit-level rain will be light (cumulative ~2 mm), mostly during the morning, with temperatures hovering around 4 °C and light winds (~15 km/h) that ease further into the night. At the 8th station (~3,400 m), conditions will be mild (6 °C) with damp trails but calm air. Cloud cover is expected to thin by early morning, transitioning to partly clear skies—a good prospect for summit visibility at dawn. Japanese meteorological commentary highlights residual low clouds but notes improving clarity by sunrise as moisture diminishes and winds shift. Climbers should still carry waterproof shell, warm mid-layers, gloves, headlamp, and traction aids. With proper gear and caution, this looks like a favorable overnight climb and sunrise opportunity.

Daily forecast for July 18

Climbers starting from Mt. Fuji’s 5th station on July 18 and aiming for a sunrise summit on July 19 can expect improving conditions after afternoon showers. Rain is likely earlier in the day but should taper off by evening, with winds easing from around 45 km/h to 20 km/h overnight. Temperatures at the 8th station (~3,400 m) will be around 8–9 °C, with summit wind chills near 0 °C. Trails will be damp but cloud cover is forecast to gradually clear through the night. Sunrise visibility at the summit is looking favorable, with a good chance of partial to mostly clear skies. While not severe, conditions will still be cold and wet at higher elevations. Climbers should bring full waterproof layers, warm insulation, gloves, lights, and traction for the trail. With proper preparation, this window offers one of the better sunrise opportunities in recent days.

Daily forecast for July 17

Climbers planning to depart Mt. Fuji’s 5th station on July 17 and summit for sunrise on July 18 can expect improving weather conditions after a wet and windy start. Moderate to heavy rain is expected to begin in the afternoon on July 17, with winds near the summit reaching 45–55 km/h from the southwest. Temperatures at the 8th station (~3,400 m) will be around 7–9 °C, dropping to 5 °C with wind chill, while summit wind chill will approach 0 °C. Rain will likely continue into the night, but precipitation is forecast to taper off before dawn, and cloud cover is expected to begin lifting. By sunrise on July 18, skies are forecast to partially clear, offering a real chance of visibility at the summit—an improvement from the whiteout conditions of recent days. Japanese meteorological commentary notes that while rain and low clouds will persist through the night, visibility is expected to recover around sunrise as moisture decreases and winds shift. While the approach will still be wet and cold, sunrise visibility looks promising. Climbers should be well-prepared for exposure: waterproof layers, warm insulating clothing, gloves, and reliable lighting are essential. The outlook is improving, but only those equipped and experienced for wet, high-altitude travel should proceed.

Daily forecast for July 16

Climbers planning to ascend Mt. Fuji from the 5th station on July 16 and summit for sunrise on July 17 should be prepared for challenging conditions. Rain is expected to begin around midday on the 16th and continue through the night, with wind speeds increasing to 45–50 km/h by evening at the 8th station (~3,400 m). Overnight temperatures will be around 6–9 °C, with wind chill making it feel closer to 5 °C, and near 0 °C at the summit. Morning summit conditions will remain wet and windy, with dense cloud cover expected to limit visibility and obscure views. Trail surfaces will likely be slick and unstable, especially in the dark. While conditions are not extreme, they present real risks for those without proper waterproof gear, cold-weather layers, and experience in poor visibility. Climbers should monitor updates carefully, pace themselves conservatively, and consider postponing if not fully equipped or confident in high-altitude, wet-weather travel.

Daily forecast for July 15

Climbers planning to ascend Mt. Fuji from the 5th station on July 15 and summit for sunrise on July 16 face serious and potentially dangerous conditions. Forecasts predict intense overnight rain, winds up to 70 km/h, and dense cloud cover, with summit temperatures near freezing once wind chill is factored in. Visibility will be poor, trails slick and unstable, and the chance of sunrise views is low. Rapid weather changes are likely, creating life-threatening exposure risks, especially for those unfamiliar with high-altitude navigation in zero-visibility conditions. Without a professional guide, navigating the trail safely in the dark, cold, and wind is highly inadvisable. Climbers lacking proper gear, experience, or weather readiness should postpone or go with an expert—this is not a safe night for casual or unaccompanied attempts.
