Conditions on this page are recalculated from the latest forecast every time it is opened, for the current date in the location's own time zone.
For seated outdoor events like weddings, temperatures between 20-26°C (68-79°F) keep guests comfortable in formal attire. Below 18°C consider heaters; above 30°C requires significant cooling measures. 1-3 day forecasts have 85-95% accuracy—use this window for final decisions. 4-7 days have 70-80% accuracy—prepare backup options. Beyond 8 days, use historical averages for initial planning. Winds under 15 km/h are manageable. Above 25 km/h, decorations can topple, table settings blow away, and conversation becomes difficult. Secure all items or consider backup plans. A comprehensive guide to planning weather-dependent outdoor events. Learn how to read forecasts, set up backup plans, and choose the best dates for weddings, parties, and celebrations. Rain hit exactly during the 45-minute ceremony window. Guests rushed inside, floral arrangements toppled in wind, timeline collapsed. A 30% rain chance during a 2-hour ceremony window is not low risk. Always check hourly precipitation timing, not just the daily percentage. One wrong weather call can ruin months of planning. A perfect 24°C forecast means nothing if wind hits 30 km/h, rain arrives during your ceremony, or humidity makes guests uncomfortable within minutes. This guide shows you exactly how to avoid that — using a simple decision framework. Weather forecasts become progressively less accurate further into the future. This fundamental truth should guide your planning timeline. Modern forecasting provides excellent accuracy within 3 days, reasonable confidence up to 7 days, and general trends beyond that. For major events like weddings, select your date based on historical weather patterns for your region, then monitor forecasts as the date approaches. Make final venue and setup decisions 48-72 hours beforehand when forecasts are most reliable. Guest comfort depends on more than just temperature. Wind chill, humidity, and sun exposure all combine to determine whether your event feels magical or miserable. Candles blow out, table settings topple, conversation becomes strained, and hair styling gets ruined. At 30+ km/h, lightweight decorations become projectiles. Weddings demand special care because of formal attire, photography needs, and emotional stakes. A forecasted "nice day" can still fail if wind, humidity, or sun angle are wrong. Pro tip: Schedule your ceremony to conclude 30-60 minutes before sunset for optimal golden hour photography, then transition to reception as temperatures become comfortable for evening dining. Every outdoor event needs a backup plan that feels like a planned choice, not a last-minute scramble. The key is making the switch seamless for guests and vendors. Ambiguity causes chaos. Your caterer, florist, and DJ all need lead time to adjust. Moderate temperatures but higher precipitation risk. Weather changes rapidly — backup plans are non-negotiable. Wind is often stronger, affecting decorations and setup. Best statistical chance of dry weather, but heat management is critical. Schedule around peak heat (avoid 12-3pm for outdoor ceremonies). Provide shade, water stations, and fans. Often ideal temperatures with beautiful natural colors. But days shorten fast — start events earlier to maximize daylight. Temperature drops quickly after sunset. Magical with proper infrastructure, but demands significant heating and weather protection. Indoor backup is essential, not optional. Don't rely on a single forecast source. Check multiple services for consensus, and focus on.
