Sudden summer has struck a fever in the Toronto cycling community
Exclusive look at your cycling commute forecast this week across the Greater Toronto Area.
This forecast is as perfect as you can expect for commuters, as you’ll be able to ditch the typical layers by late-week for those morning commutes or rides. Pick sunglasses with a low visible light transmission (<18%), but be prepared for more clouds at times later in the week.
Monday: A light southeast lake breeze develops across the Greater Toronto Area (GTA) at 10-25 km/h with full sun all day down by the lake - little more clouds across the southwestern GTA, with highs in the low 20's away from Lake Ontario.
Tuesday: We're adding 2-3°C to the inland temperatures compared to Monday, 24-25°C for the northwestern GTA away from the lake influence, 18-20°C beside the lake. No significant humidex values. Lighter winds than Monday: 10-20 km/h peak lake breeze out of the southeast. Fair weather clouds speckled across the north GTA along a boundary. Last morning with lows in the 10°C range, they'll creep towards the mid-teens by late-week.
Wednesday: Likely no arm-warmers needed in the morning here on out. A weak upper-level wave swoops in around the high, adding a little moisture plus increasing the humidex just a tick. There's an increasing threat of cloud cover in the afternoon, accompanied by a southeast lake breeze of 10-20 km/h. Little to no threat of rain.
Thursday: Warmest day of the week (so far), but comes with more variable cloud cover. Temperatures ticking towards the upper 20's across the northwestern GTA, downtown Toronto low-to-mid 20°S with a very light lake-breeze of 5-15 km/h. Perhaps a shower or two for the north GTA, but the signal remains weak. The first day that truly feels a tad muggy - take an extra bidon.
Friday: Some confidence is there for a wind shift to the southwest at 15-30 km/h, limiting the natural air-conditioning/cooling of the lake - upper 20's to near 30°C for most of the GTA, with shoreline sections bumping well into the mid-20s in pockets. Partly cloudy conditions, but it will feel like the mid-30s away from the lake and muggy. Bring at least two water bottles on any rides over 40 km.
