Tel Aviv has a Mediterranean climate: long hot summers, mild wet winters, and almost three hundred sunny days a year. Spring (March to May) and autumn (October to November) are the most comfortable times to visit.
Spring brings mild dry weather with wildflowers across the surrounding countryside. Daytime temperatures range from about 18 to 25°C, evenings cool enough for a jacket. Easter and Passover fall in March or April; the city stays busy, particularly with religious pilgrims to Jerusalem.
Summer is hot, dry, and humid — June through September daytime highs of 28 to 32°C, with high coastal humidity. There is essentially no rain, the beach is busy from morning to night, and the bars and clubs run later than at any other time of year. The White Night Festival (Layla Lavan), in late June, is one of the highlights.
Autumn is the second mild season — warm sea, calmer crowds, occasional rain by November. The Jewish High Holidays (Rosh Hashanah, Yom Kippur, Sukkot) fall in September or October and shut down most of the city for at least a day each.
Winter is cool and wet — temperatures 10 to 18°C, with significant rain from December through February. Bring an umbrella and warm layers; some bars and cafés use outdoor heaters but most are indoor-only. Hanukkah lights illuminate the city in December.
