Summer Weather in Osaka (June/July/August)

Osaka sits in a basin, surrounded by tall buildings that hinder natural airflow, leading to the city's infamous urban heat island effect. As a result, summers here can be intensely hot, with temperatures often climbing above 30℃ (86℉).

The rainy season, or "tsuyu" as it's called in Japanese, arrives in June, bringing with it a significant amount of rainfall. A lightweight, compact umbrella that's suitable for both rain and sunshine is a wise addition to your packing list.

Additionally, the season can bring typhoons. If you're planning a visit, staying updated on weather forecasts and typhoon tracking is crucial to avoid any unforeseen issues.

To help you navigate the summer heat in style, Nemi, a Taiwanese editor at LIVE JAPAN who has called Osaka home for five years, offers her top tips for enjoying the city.

In June, despite the rain, the beauty of hydrangeas captivates visitors. These flowers, particularly charming after showers, can be found even in Osaka's bustling areas like Namba and Shinsaibashi.

July is the peak of summer in Osaka, with temperatures often below 30°C (86°F) but daily highs frequently surpassing 30°C (86°F), especially around noon, making it the hottest month.

In July 2023, Osaka experienced temperatures over 30°C (86°F) daily. Beyond sunscreen, staying hydrated is key, with salt-containing drinks being particularly effective for both hydration and salt replenishment. This approach has been crucial for avoiding heatstroke during Osaka's summers.

Mosquito activity increases with the heat, so using repellent sprays or patches is important, especially for protecting young children who may be more vulnerable. Consider buying mosquito repellent products like stroller strips in Japan; they're airplane-friendly, allowing worry-free shopping.

Visiting Osaka in July also offers the chance to experience traditional festivals and bon dances, akin to those seen in Japanese dramas and anime, making for unforgettable memories.

In July, Osaka hosts numerous traditional events including festivals, bon dances, and fireworks displays throughout the city. I particularly recommend the Tenjin Matsuri held at the end of July!

This festival has been celebrated in Osaka for over 1,000 years and is one of Japan's three major festivals. It's definitely worth experiencing, especially the grand finale featuring the Tenjin Fireworks Display, which is truly magnificent. I suggest purchasing tickets for designated seating areas to enjoy the fireworks comfortably. However, since it's an outdoor event, remember to stay hydrated to avoid heatstroke!
