“Five Things You Need to Know Today” is a Patch column that provides readers with essential, daily information at a glance.

1. Cooler weather: After a few days of hot and humid weather, things will cool down a little today, with a high near 76 degrees and a low around 54, according to the National Weather Service. The day will be partly cloudy, and the evening will be mostly cloudy.

2. Pool party: Come celebrate Rosemary Pool’s 40th birthday with a party tonight from 6-7:30 p.m. Enjoy games, crafts, music, a memory mural and birthday cake. Cost is $3 after 6 p.m., or come early and swim. Rosemary Pool opens at 12:30 p.m. daily.

3. Another chance to watch: If you missed the premiere of the Needham documentary, “Big Little Town,” on WGBH yesterday, there are more opportunities to watch it. The film will air today at 2:30 p.m. on WGBX (Channel 44) and through the weekend. See the full schedule here.

4. Friday Flick: Drop by the Stephen Palmer Senior Center at 1 p.m. today for a free showing of the 2011 film “The Artist.” For a look at other programs and classes offered by the Council on Aging, check out our weekly roundup, which runs every Saturday afternoon on Needham Patch.
