A gloriously sunny weekend is perfect for outings.
Tips
usage
The go-to set phrase for 'sunny and pleasant'. 明媚 ('bright and lovely') is key — it adds warmth and charm beyond plain '阳光'. Very common in weather reports, travel writing, and openings of compositions (作文).
memory
媚 ('charming / alluring') takes a bright sunny day and makes it flirty — the sun is flattering you. This is why 阳光明媚 sounds nicer than the flatter 天气晴朗.
