When using a canopy in summer, there are several precautions to consider:

1. 防止日曬：夏季陽光強烈，使用雨棚時應盡量選擇遮陽性能好的材料，如遮陽布或遮陽網，以防止陽光直射。此外，可以考慮增加雨棚的高度或傾斜度，以獲得更好的遮陽效果。

1. Prevent exposure to sunlight: In summer, when using a canopy, it is recommended to choose materials with good shading performance, such as sunshade cloth or shading net, to prevent direct sunlight. In addition, increasing the height or inclination of the canopy can be considered to achieve better shading effects.

2. 通風透氣：夏季氣溫高，雨棚內部很容易變得悶熱，影響舒適度。因此，在設計和選擇雨棚材料時，應考慮通風透氣性能。可以選擇有通風口或花紋的材料，以增加空氣流通。

2. Ventilation and breathability: In summer, when the temperature is high, the interior of the canopy can easily become stuffy, affecting comfort. Therefore, when designing and selecting canopy materials, ventilation and breathability should be considered. You can choose materials with vents or patterns to increase air circulation.

3. 防水防潮：盡管夏季降雨較少，但仍需要考慮雨棚的防水性能，以應對可能的陣雨或暴雨。建議選擇防水性能好的材料，并確保雨棚的連接處緊密，避免雨水滲漏。

3. Waterproof and moisture-proof: Although there is less rainfall in summer, it is still necessary to consider the waterproof performance of the canopy to cope with possible showers or rainstorm. It is recommended to choose materials with good waterproof performance and ensure that the connection of the canopy is tight to avoid rainwater leakage.

4. 檢查固定結構：由于夏季風力較大，特別是在沿海地區或高樓林立的城市，雨棚的固定結構非常重要。在使用雨棚前，應檢查固定點、連接處和支撐架的穩固性，確保能夠經受住大風的考驗。

4. Check the fixed structure: Due to strong summer winds, especially in coastal areas or cities with towering buildings, the fixed structure of rain sheds is very important. Before using the canopy, the stability of the fixing points, connections, and support brackets should be checked to ensure they can withstand the test of strong winds.

5. 定期清潔維護：夏季容易積累灰塵、樹葉等雜物，影響雨棚的美觀和使用壽命。因此，定期清潔雨棚是必要的。可使用軟刷灰塵，并定期清洗材料表面，避免雜物堆積。

5. Regular cleaning and maintenance: In summer, it is easy to accumulate dust, leaves, and other debris, which affects the appearance and service life of the canopy. Therefore, regular cleaning of the canopy is necessary. Soft brushes can be used to remove dust and regularly clean the material surface to avoid debris accumulation.
