July in Philadelphia is the hottest month of the year, and that 89°F average high has a direct, measurable effect on how you play. Heat above 85°F accelerates fatigue, and when the low only drops to 71°F overnight, the turf never fully recovers — expect firmer fairways early but muggy, heavy air that actually costs you a touch of carry distance on longer clubs. The 18-day precipitation count, the wettest figure of the year, means roughly one in every two rounds has some chance of a shower interruption.
The calm side of July is worth noting. Peak winds sit at 10.3 mph, the lowest of any month, so approach shots hold their line and putts aren't pushed off target by gusts. That trade-off — oppressive heat and frequent afternoon storms against genuinely calm air — is what earns July its Variable badge. Scoring well here means starting early, playing fast, and knowing when to walk in.
Book the earliest available tee time — 6 or 7 AM slots put you on the course before the heat index climbs toward the mid-90s and well ahead of the afternoon convective storms that drive most of those 18 precipitation days. Mid-afternoon reservations in July carry a genuine risk of a lightning delay, not just a sprinkle. See how conditions rate hour by hour on our playability scale.
June is a noticeably more comfortable starting point: its 84°F average high and 13 precipitation days make tee times far less stressful than July's 89°F and 18 rain days, though June's peak wind of 11.5 mph runs 1.2 mph higher. Moving from July into August, the temperature eases 3°F to an 86°F average high, but precipitation days stay identical at 18, so the rain exposure doesn't relent at all heading into the next month.

At an average high of 89°F, July is the hottest month of the year in Philadelphia and genuinely uncomfortable after mid-morning. Heat illness is a real concern for walking rounds, especially since overnight lows only reach 71°F, meaning you start the day in warm, humid air. Early tee times before 8 AM make the round manageable; midday rounds in full sun are not recommended.
July ties August as the wettest month of the year at 18 precipitation days, and in summer the bulk of those come as fast-developing afternoon convective storms rather than steady morning rain. Most Philadelphia courses will suspend play and clear the course when lightning is detected within a few miles, so a midday or afternoon tee time carries a meaningful chance of a delay. Morning rounds avoid the worst of this pattern.
